TP-Link Omada Fusion 2.5G Gateway Review

ReviewTP-Link Omada Fusion 2.5G GatewayComplete edition: When Gateway,ControllerAnd Cloud Management is included in one device

One question that the SyncTech Solution team often hears when designing the Omada system is, “If there is already a Gateway, why do we still need a separate Controller?” This question is not because users do not understand the role of the Controller, but it increasingly reflects the pain points of modern network systems. Every added device means more power cables, more LAN cables, more firmware, more configuration, and another point that the IT team has to manage throughout the system's lifespan.

TP-Link Omada Fusion 2.5G Gateway is designed to change this picture by combining a Gateway for Routing, NAT, Firewall, Multi-WAN, and VPN with an Omada Controller for managing Switches, Access Points, and Clients, while also enabling system management through Omada Cloud from just a single device.

But the phrase 'all-in-one' only has value if the device still provides sufficient performance, is manageable without complexity, and does not create new limitations that outweigh the problems it is trying to solve. Therefore, this article does not just look at the appearance and specification numbers, but analyzes which types of work the Fusion concept is suitable for, how it can actually reduce the burden on system installers, and what observations should be known before using it in production systems.

The SyncTech Solution team, as a TP-Link Solution X Partner at the Gold level, along with engineers certified with Omada Master Certification, were invited to participate in the launch and experience the use of products in the Omada Fusion group. This article therefore conveys information from the product itself, technical data, and the perspectives of those who need to design, install, and maintain systems for customers to use effectively in the long term.

Scope of the article: The sections related to performance refer to the product's capability under standard testing conditions, not the benchmark results from actual customer systems. The speed achieved in each project may vary depending on the firmware, traffic patterns, number of sessions, packet size, functions enabled simultaneously, and network architecture.

What is Omada Fusion and why are this group of products interesting?

Gateways and Controllers have different roles, but both parts are located at the center of the network system. Gateways manage the traffic routes between LAN, VLAN, WAN, and VPN, while Controllers are responsible for integrating the management of Gateways, Switches, and Access Points into a single Dashboard.

In the traditional Omada system, installers may choose to use a Gateway together with an OC200, OC300, Software Controller, or Cloud-Based Controller, depending on the size and type of the project. This approach is flexible and suitable for systems that require a clear separation of device roles. However, for small offices, shops, clinics, or multi-branch businesses, having a separate Controller may add unnecessary complexity.

Fusion 2.5G therefore sits in the middle between a router for general business use and a full Controller-based Omada system. Users still gain centralized management capabilities but with one less piece of hardware, along with added tools designed to reduce installation and support time, such as Bluetooth onboarding, automatic device discovery, batch adoption, and a touch screen on the device.

Topic	Separate Gateway + Controller	Omada Fusion 2.5G
Gateway	Separate device	Built into the device
Omada Controller	Use Hardware, Software, or additional Cloud Controller	Built-in Controller ready to use
Cloud Management	Depends on the type of Controller	Managed through Cloud, Local, and Omada App
Installation start	Primarily via Ethernet or Web Interface	Supports Bluetooth and Ethernet
Devices that require power	At least Gateway and Controller	One device for two roles
Suitable for	Systems that require a separate Controller or are large-scale	Small to medium businesses and medium-sized multi-branch systems

Perspective from the SyncTech Solution engineering team
The most important selling point of Fusion is not having a screen or a 2.5GbE port, but rather reducing the number of things that need to be managed at each site. When multiplied across ten or twenty branches, the time saved from installation, updates, and support is worth more than the cost of the controller saved.

Unboxing Omada Fusion 2.5G Gateway

The packaging of Fusion 2.5G comes in a simple style. The device is neatly arranged inside shockproof material, while the accessories are clearly separated from the main unit. There are not too many parts, so installers do not need to spend a long time counting them.

Equipment found inside the box

Omada Fusion 2.5G Gateway, 1 unit
Power Adapter with USB Type-C power cable
1 Ethernet cable
Installation guide and accompanying information as per the distribution set

The provided equipment is complete for getting started with a desktop setup. You can connect WAN, connect LAN, and power on to start onboarding immediately. The wall-mount magnetic equipment and the Rack-Mount Kit are optional accessories that need to be acquired separately. If you plan to install in a rack, you should specify the complete installation set from the BOM preparation stage.

This is a detail that seems minor but actually affects real work, because ordering the main equipment without ordering the Mounting Kit might cause the on-site team to temporarily place the machine or have to return to the site again to complete the work properly.

First Impression: Gateway That Looks Like a Smart Network Appliance

When taking the device out of the box, the first impression is that the Fusion 2.5G is smaller than it appears in promotional materials. With dimensions of approximately 160 × 130 × 31.5 millimeters and a weight of around 510 grams, it doesn't take up much space on a desk or in a network cabinet.

The design uses a dark gray tone, contrasted with a black front panel and a central touchscreen. Its shape is unlike the industrial-focused Gateway Rackmounts, but it resembles modern Smart Hubs or Network Appliances. It can be placed in offices, meeting rooms, store counters, or Front Offices without making the space look like a server room.

The body is made of polycarbonate, not a metal chassis, but the assembly is solid, the weight is not so light that it feels like a consumer device, and there are no parts that move abnormally. The cooling is fanless, so there is no fan noise, making it suitable for areas where users sit close to the device.

What the team liked even before turning it on
The design of Fusion doesn’t try to look “Enterprise” with a large body, but chooses to be designed to fit the real locations of the target groups, such as restaurants, clinics, offices, and multiple-branch stores, many of which do not have a dedicated server room.

2.51-inch Touch Screen: Gimmick or Practical Tool?

The 2.51-inch color touchscreen is the most eye-catching part of the product. Placing the screen on the Gateway may make many people question whether it is necessary, because the actual system settings still need to be done through the Controller or Web Interface anyway.

The answer is that the screen is not intended to replace the Dashboard but serves as a "status window" for on-site tasks. Administrators can check Network Health, internet status, WAN, Real-Time Traffic, Alerts, and use preliminary data to help diagnose the cause of problems without having to open a Notebook every time.

Imagine a situation where a customer calls to report that "the internet is slow," but the person on site is not from the IT department. If the device can display WAN status and alerts directly, the support team can have the coordinator check the basic information over the phone more easily than teaching them to log in to the controller.

The screen does not make the system faster, but it helps the support process run faster, which is very valuable at sites that are far away or have high travel costs.

What the screen is good at helping with

Check whether the WAN is still online
View traffic and system status quickly
Observe alerts before entering the dashboard
Use as reference information for phone support
Reduce opening a notebook for basic inspection tasks

Things the screen did not replace

In-depth log inspection
Creating VLANs and ACLs
Packet flow inspection
Analysis of complex routing or VPNs
Modifying large configurations

5 Ports of 2.5GbE and the Flexibility of Multi-WAN

The rear has five 2.5Gbps RJ45 ports, consisting of one fixed WAN port and four LAN/WAN ports with adjustable roles, allowing up to four simultaneous WAN connections.

1 × 2.5G RJ45 WAN
4 × 2.5G RJ45 LAN/WAN
USB Type-C for power supply
Reset button

Providing every port as 2.5GbE means more than just supporting faster than 1Gbps internet, because it helps reduce bottlenecks when connecting to a Multi-Gigabit Switch, Wi-Fi 7 Access Point, or NAS that supports 2.5GbE.

However, Fusion 2.5G does not have SFP or SFP+ ports. If the project requires a direct Fiber Uplink, it must be connected through an ONT, Media Converter, or an appropriate Switch. This point should be carefully considered in multi-story building projects or factories using a Fiber Backbone.

Example of Portfolio Organization in the Office

Port	Example Function
WAN 1	Main Fiber Internet
LAN/WAN 1	Backup Fiber Internet
LAN/WAN 2	5G Router for Emergency Failover
LAN/WAN 3	Private WAN or Intranet
LAN/WAN 4	Uplink to Managed Switch

Precautions
Multi-WAN does not mean combining the speeds of all connections to make a single session faster according to the sum. Load balancing usually occurs at the Session or Policy level, and when a WAN changes its Public IP, some applications may need to reconnect.

What does Capacity 30 devices mean?

The number 30 devices refers to all Omada devices managed by the Controller, not 30 Access Points plus additional Switches. For example, 1 Gateway, 4 Switches, and 20 Access Points would equal a total of 25 devices used.

A good design should not use full capacity from day one. There should be room for adding at least Access Points, Switches, or backup devices in the future. If the site is likely to grow beyond this limit, separating the Controller might be a more suitable approach.

Getting Started with Installation: How Does Bluetooth Onboarding Help?

An interesting step after powering on the device is to start the setup via the Omada App using Bluetooth. Installers do not need to search for the default IP, change the notebook's IP, or plug in a LAN cable to access the first-time setup page.

Bluetooth is not used as the main management channel of the system, but as a shortcut during onboarding, helping to discover devices and guide installers through the steps of setting up the Site, Administrator, WAN, and connecting to Omada Cloud.

For people who install equipment only a few times a year, the time saved may not seem much, but for System Integrators who need to prepare ten or twenty sites, reducing repetitive steps clearly affects the overall project time.

Information to Prepare Before Starting Setup

Site name and device naming standards
Static IP, Dynamic IP, or PPPoE information
PPPoE Username and Password
LAN, VLAN, and DHCP plan
TP-Link ID that will own the Site
List of administrators and their permission levels
List of Switches and Access Points to be Adopted

Best Practice
The simplicity of the Wizard does not replace designing the Network before installation. Do not start the Setup until there is a clear IP Plan, VLAN Plan, and WAN information, because changing the structure after users are already in place often takes much more time than planning from the beginning.

Built-in Omada Controller: The Heart of the Word Fusion

Once the setup is complete, the on-device controller will begin managing the Gateway, Switch, Access Point, and Clients within the same site. Administrators can view the Dashboard, Topology, Device List, Client List, Logs, Alerts, Internet Activity, and update Firmware from a central location.

The advantage of combining Controllers is that there is no need to prepare an additional OC200 or Software Controller, no need for another Power Adapter, and no need to constantly check whether the separate Controller is still online.

On the other hand, combining the two roles into a single device causes the Gateway and Controller to share a failure domain. If the device goes down, both internet connectivity and site management will be affected simultaneously. Therefore, a backup configuration and a device replacement plan should be in place according to the business's priority level.

Key Management Functions

Cloud Access and Local Management
Omada App
Multi-Site Management
Restore and Backup
Automatic Device Discovery
Network Topology
Dashboard
Device List and Client List
Logs, Alerts and Events
Batch Firmware Upgrade
Health Monitoring
Internet Activity
Captive Portal
RADIUS and LDAP Authentication
802.1X Authentication
OUI-Based VLAN
SNMP v1, v2c and v3

Automatic Discovery and Bulk Adoption help reduce on-site time

After connecting the Omada Switch and Access Point to the Network, the Controller can automatically detect devices and display the list of devices ready to be Adopted. Afterwards, the installer can select multiple devices and import them into the system at the same time.

The benefits are most apparent in projects with multiple Access Points, because there is no need to log in and configure each device individually. However, you should check the model, MAC Address, Serial Number, and installation location before adopting to prevent bringing devices from the wrong site into the system.

How to name devices to make support easier?

SW-Core-Rack01
SW-PoE-Floor02
AP-Lobby
AP-MeetingRoom-A
AP-Warehouse-Zone01

A good device name helps the Support team know the location immediately when an Alert occurs, while names like AP-01 or Switch-03 might be fine on the installation day but create confusion when the team changes members or the system expands.

Cloud Management and Multi-Branch Care

Fusion 2.5G supports management through Cloud, Local Web, and Omada App. Administrators can monitor the status of Sites, Gateways, Switches, Access Points, and Clients remotely without opening Management Ports from the Internet directly to the Gateway.

For businesses with multiple branches, this helps reduce travel and allows the IT team to see problems more quickly, such as which branch is offline, which access point is down, or which site has unusually high traffic.

Jobs Suitable for Working via Cloud

Check the status of the Site and devices
View Alerts, Logs, and Events
Check Client and Internet Activity
Check Topology
Update Firmware according to the plan
Adjust Configurations with low risk

Jobs to be cautious of when working remotely

Change WAN Configuration
Change Management VLAN
Modify Default Route or Policy Routing
Create ACL that may block the Controller
Change the IP Address of the LAN
Shut down the Uplink port

Adjustments that may cause the site to go down should have a technician or coordinator on site, along with a clear backup and rollback plan.

Multi-WAN in the Real World: It's Not Just Plugging in Multiple Internet Lines

Fusion 2.5G supports Load Balancing and Automatic Failover, allowing up to 4 WAN connections to be set. However, the real benefit depends on the Policy design, not the number of cables connected.

Case of a 100-Person Office

Assume the office has a primary Fiber Internet line, an additional Fiber line from another provider as a backup, and a 5G Router for emergencies. A suitable design might have regular work traffic use WAN 1, Guest Wi-Fi partially distributed to WAN 2, and reserve WAN 3 for failover when the Fiber has issues.

When the primary WAN fails, Fusion can reroute to the backup WAN, reducing the downtime for users who cannot access the internet. However, sessions that are currently connected through the original Public IP, such as VPN, Remote Desktop, Banking, or certain types of VoIP, may be disconnected and need to reconnect.

Case with Private WAN

Some organizations have a second WAN as an Intranet or Private Network that only allows access to specific systems. Traffic to such destinations must use the correct Static Route or Policy Routing, and the return route at the destination must also be checked, because having only the outgoing route does not guarantee that the response will return via the correct path.

Perspective from the engineering team
Most Multi-WAN issues don’t arise from the gateway not knowing where to send traffic, but from NAT, session persistence, health check, and return route not being fully designed. Therefore, failover testing must test the actual application, not just check whether a ping can reach the internet.

VLAN: A function that affects security more than speed

Fusion supports VLAN Segmentation and multiple Network DHCP, suitable for separating systems according to user and device types, such as Staff, Guest, POS, CCTV, IoT, Server, and Management

Example for a Restaurant

VLAN	System	Access Guidelines
10	POS	Access to Payment Gateway and required Servers
20	Staff	Use the Internet and internal work systems
30	Guest Wi-Fi	Internet access only, no LAN access
40	CCTV	Connect to NVR and designated management points
50	IoT	Restricted to necessary services only
99	Management	For Gateway, Switch, and Access Point

If everything is on the same VLAN, guests connected to the Wi-Fi might be able to see devices inside the store, and IoT devices with vulnerabilities could become a starting point for attacks on the POS system. Therefore, VLAN segmentation is not just about organization, but also a basic security measure for business networks.

Routing, NAT, and Network Services

Fusion supports Static Routing, Policy Routing, DHCP Server, DHCP Reservation, Multi-Net DHCP, Virtual Server, DMZ, One-to-One NAT, Disable NAT, UPnP, ALG, Dynamic DNS, IPv6, Bonjour/mDNS, and IGMP Proxy

These functions cover a fairly wide range of general business uses, but only the necessary ones should be enabled. For example, UPnP allows devices to open ports automatically, which is convenient, but in an organizational system, it may not be suitable if you need to clearly control every inbound rule.

When is Policy Routing used?

Force Guest Wi-Fi to go out through WAN 2
Allow the backup system to use a dedicated circuit
Route traffic to the head office via Private WAN
Assign servers to use a specific Public IP
Separate traffic for each department according to organizational policy

QoS: Making critical systems no less important than Guest Wi-Fi

QoS and Bandwidth Control are useful when bottlenecks occur. Consider a restaurant at lunchtime with many customers connected to the Guest Wi-Fi, while the POS is sending orders and staff devices are using the Cloud system. Without traffic prioritization, downloads or streaming might compete for bandwidth with the systems that generate revenue for the business.

Fusion supports Auto QoS and policy customization to ensure that important applications receive priority first, such as POS, VoIP, Video Conference, ERP, or Remote Desktop.

Best Practice
QoS works well when the Bandwidth is set close to the actual circuit speed. If set much higher than the actual speed, the Gateway may not detect bottlenecks and may not be able to manage the Queue as expected.

Performance by Job Type

Item	Approximate Performance
Static IP NAT	Upload 2,362Mbps / Download 2,361Mbps
DHCP NAT	Upload 2,363Mbps / Download 2,359Mbps
PPPoE NAT	Upload 2,355Mbps / Download 2,357Mbps
IPS	Upload 2,183Mbps / Download 2,152Mbps
DPI	Upload 2,206Mbps / Download 2,219Mbps
IPsec VPN	Approximately 972–1,087Mbps depending on encryption and authentication sets
WireGuard VPN	605Mbps
Omada LightLink VPN	527Mbps
L2TP VPN	892Mbps
SSL VPN	250Mbps
OpenVPN	223Mbps
PPTP	193Mbps

These numbers help indicate the level of the product, but they should not be used to guarantee results in every system. When IDS/IPS, DPI, Content Filtering, VPN, and Logging are enabled simultaneously, the processing load will differ from testing each function separately.

Security: It's not just about turning on IDS/IPS and considering it done

Fusion has multiple security tools, including Stateful Firewall, IDS/IPS, DPI, Application-Based ACL, Content Filtering, Ad Blocking, Safe Search, DNS Security, Attack Defense, ARP Inspection, MAC Filtering, and IP-MAC Binding

What do IDS and IPS help with?

IDS detects traffic that matches threat patterns and alerts, while IPS can prevent or block according to policy. This capability helps increase visibility and reduce risk from traffic with dangerous patterns, but it does not replace endpoint protection, patch management, backup, or user training.

Enabling IPS should start by checking Alerts and adjusting Policies before strictly blocking in the Production system because some types of Signatures may affect specific organizational Applications.

DPI and Application Visibility

DPI helps to see which type of applications are using the bandwidth, not just the IP and Port. This information can be used together with QoS and Application-Based ACL to control Streaming, Peer-to-Peer, Social Media, or Cloud services according to organizational policies.

Content Filtering and Safe Search

The system can control websites by category, using Allow List, Block List, Ad Blocking, and Safe Search. It is suitable for offices, schools, clinics, and Guest Networks, but policies should be balanced. Overly broad blocking may interfere with actual work and increase the Helpdesk workload.

Secure DNS

Supports DNSSEC, DNS over HTTPS, DNS over TLS, and DNS Redirection, helping to enhance DNS control within the system. However, policies should be clearly defined on whether clients are allowed to use external DNS or are required to go through the organization's designated DNS, because some browsers and applications may use their own Secure DNS.

ARP Inspection and IP-MAC Binding

These functions help reduce the risk of certain types of forgery within a LAN, but they need to be planned appropriately for DHCP and devices that frequently change location. If the Binding is set incorrectly, the Client may not be able to use the Network.

Security Best Practice
Start by segmenting VLANs, use Default Deny between networks that don’t need to communicate, update Firmware, back up Configurations, and regularly check Alerts. Security functions are only useful if someone monitors and adjusts Policies to fit the actual system.

VPN supports both Remote User and Site-to-Site

Fusion supports WireGuard, IPsec, OpenVPN, SSL VPN, L2TP, and PPTP in the roles of Server, Client, or Site-to-Site depending on the Protocol, thus supporting both existing systems and various new installations.

Protocol	Suitable for	Remarks
WireGuard	Remote Access and Site-to-Site that require easy setup and good performance	Should clearly define Key Management and Routing
IPsec	Connect headquarters, branches, and devices of different brands	Proposal, Route, NAT, and Phase must match
OpenVPN	Remote User and systems that require broad Client support	Throughput is lower than WireGuard and IPsec
SSL VPN	Remote Access for organizational users	Check supported Client and Firmware
L2TP	Supports legacy systems and some types of Clients	Should choose a newer Protocol when starting a new project
PPTP	Compatibility with old systems	Not recommended for important data

Number of Supported Tunnels

IPsec VPN up to 20 Tunnels
SSL VPN up to 80 Tunnels
OpenVPN up to 110 Tunnels
Omada LightLink supports up to 253 Clients

The number of Tunnels is only one aspect of capacity; it is also necessary to consider total throughput, the number of sessions, and the amount of traffic each tunnel uses simultaneously.

Omada LightLink VPN: Reducing Remote Access Steps

LightLink VPN is designed for administrators to invite users via Link or Email, reducing the complexity of distributing Profiles and setting up a traditional VPN, along with Smart Split Tunneling that sends only necessary traffic into the Tunnel.

For example, employees working from home may need to send traffic to NAS, ERP, and Remote Desktop through a VPN, but general websites and video streaming can go directly to the internet from home. This method reduces the bandwidth burden at the headquarters and provides users with a smoother experience than a full tunnel in many cases.

However, the use of Remote Access must be accompanied by secure authentication, revocation of access rights when employees leave, and a review of which Subnet each user group can access.

Full Mesh SD-WAN for Multi-Branch Businesses

Fusion supports Full Mesh SD-WAN, connecting up to 20 sites and allowing the creation of Direct Inter-Site Links without routing all traffic through the headquarters. Configuration is done through the Omada Cloud Portal.

Example of a company with a headquarters and 4 branches

The Hub-and-Spoke system forces branch A to contact branch B through the headquarters, even if both branches are in the same province. Full Mesh allows sites to communicate directly, reducing latency and the workload on the headquarters' WAN.

Previously, when using Full Mesh, it is advisable to set the Subnet for each Site to avoid duplication, establish Firewall Policy between branches, and check whether the business really requires all branches to see each other. Some organizations should allow communication only between branches and the Data Center rather than opening communication in a Full Mesh manner for everything.

Precautions
SD-WAN helps reduce the complexity of creating tunnels but does not solve the problems of duplicate IP addresses, overlapping routes, internal DNS, or unclear access permissions. These issues still need to be planned before deployment.

Diagnostics Tools for Support Work

The built-in controller has tools such as Ping, Packet Capture, Terminal, Cable Test, Interference Detection, Remote Access, IntelliRecover, and Port Mirroring, which help the support team analyze problems more centrally.

Example of Usage

Ping and Traceroute: Check route and reachability
Packet Capture: Check DHCP, DNS, TCP handshake, and abnormal sessions
Cable Test: Help detect cable problems on supported devices
Interference Detection: Check wireless environment together with supported Access Points
Port Mirroring: Send traffic to external analysis tools
Syslog and SNMP: Connect to the organization's monitoring system

These tools reduce the number of trips needed, but the Support team still needs to understand the Protocol and Topology to interpret results correctly. Having a Packet Capture does not mean you can immediately find the cause if you don't know what to look for.

Comparison of Fusion with using Gateway + OC200

Topic	Fusion 2.5G	Gateway + OC200
Number of devices	Fewer	Separate Gateway and Controller
Installation	Easier and faster for appropriately sized sites	Flexible placement of a separate Controller
Failure Domain	Gateway and Controller in one device	Controller separate from Gateway
System expansion	Suitable for a fixed capacity	Controller can be chosen according to system size
Space and cabling	Uses less	More
Suitable for	New projects and small to medium businesses	Existing systems, large systems, or projects requiring separated roles

Already have OC200, should I change it?

There is no need to switch just because Fusion is a new product. If the existing Gateway and OC200 still support the capacity and requirements well, continuing to use them may be more cost-effective. Fusion is most suitable when starting a new project, needing a 2.5GbE port, or wanting to reduce the number of devices at each branch.

Obvious Advantages

Combines Gateway and Controller in a single device
All 5 ports are 2.5GbE
Supports up to 4 simultaneous WAN connections
Cloud Management without needing per-device licenses for the internal Controller
Bluetooth onboarding and batch adoption help reduce installation time
Touchscreen allows on-site status monitoring
Routing, Security, VPN, and SD-WAN functions are fairly complete
Fanless operation, quiet performance
Can be installed on Desktop, Wall Mount, or Rack Mount with accessories
Suitable for managing multiple small branch offices centrally

Observations to Know

No SFP or SFP+ ports
No PoE; a PoE switch is required for the access point
Controller recommended for up to 30 Omada devices in total
Gateway and controller use the same hardware; if the device stops working, both roles are affected
Wall-mount and rack-mount kits are sold separately
Actual performance may decrease when multiple functions are enabled simultaneously
Full Mesh SD-WAN must be configured through the Cloud Portal
Not a device for data centers or systems requiring 10GbE and high-level high availability
Cost-effectiveness should be considered together with the actual selling price and existing devices in the organization

Who should consider Omada Fusion 2.5G?

Organizations that are starting to build a new Omada system
Offices, restaurants, shops, clinics, or small to medium hotels
Businesses with multiple branches that want to manage from the Cloud
Projects that require Multi-WAN and 2.5GbE ports
Organizations that are upgrading to Wi-Fi 7
System Integrators and MSPs who want to reduce the number of devices per site
Those who want a built-in Controller without installing an additional Server

Who might be better suited to another approach?

Systems with Omada Devices clearly exceeding capacity
Data Centers or headquarters that require 10GbE/25GbE
Projects that require SFP+ Uplink directly from the Gateway
Organizations that mandate the Controller to be separated in a failure domain from the Gateway
Systems that require specialized Firewall Features, Compliance, or Threat Intelligence
Organizations with existing Gateways and Controllers that are still functioning well

Frequently Asked Questions about Omada Fusion 2.5G

Can Omada Fusion 2.5G replace OC200?

Can be used on Sites where the number of devices and Clients are within the Capacity of the Built-in Controller and there is no need to separate the Controller from the Gateway

Do I need to purchase an additional license for each device?

Built-in Controller supports Cloud Management without the need to purchase an additional Device License for basic capabilities within the supported scope.

How many Omada Devices are supported?

Maximum recommendation of 30 devices including Gateway, Switch, and Access Point

How many clients are supported?

Recommended maximum of 300 clients connected simultaneously. Actual experience depends on traffic and enabled features.

Is there PoE?

No. If you need to power the Access Point, you must use a PoE Switch or PoE Injector.

Is there an SFP port?

No, all network ports are RJ45 2.5GbE

Can it be used with Wi-Fi 7?

Yes, and the 2.5GbE port is suitable for Wi-Fi 7 Access Points that require uplink speeds greater than 1Gbps, but a PoE switch with sufficient power is still needed.

How many internet lines are supported?

Supports up to 4 WAN ports simultaneously

Does Multi-WAN combine the speed of all connections into a single session?

In general, it is not Load Balancing. Distributing sessions or traffic according to policy does not automatically allow a single session to achieve the combined speed of all WANs.

After failover, the existing session will not be lost, right?

Sessions are not guaranteed; certain types may be disconnected if the route or Public IP changes and will need to reconnect.

Does it support Site-to-Site VPN?

Supports WireGuard and IPsec for Site-to-Site

Which VPN protocol is suitable for the new system?

WireGuard and IPsec are interesting options, depending on the endpoint devices and requirements, while PPTP should not be used with important data.

What is Omada LightLink VPN?

It is a Remote Access approach that reduces the steps of inviting users via Link or Email, along with Smart Split Tunneling to send only the necessary Traffic through the VPN.

How many sites does Full Mesh SD-WAN support?

Supports up to 20 sites and can be configured through the Omada Cloud Portal

Can it be used locally without connecting to the Cloud?

Supports Local Management, but some functions, such as multi-site management and certain SD-WAN features, require a Cloud Platform.

Can the touchscreen control all system settings?

No, the screen focuses on status monitoring and basic troubleshooting. Advanced settings are still done through the Controller, Web, or App.

Should we switch from ER707-M2 to Fusion?

Consider the built-in controller requirements, ports, capacity, and total cost. It is not necessary to change if the existing system still meets the needs and has a functioning controller.

Can Fusion be used together with OC200?

The Controller architecture should be clearly defined for each Site. A single device should not be adopted and managed by two Controllers simultaneously.

Is it suitable for factories?

Suitable for offices, factories, or small-scale systems that use RJ45 and are within capacity limits. However, if a fiber backbone, industrial ports, redundancy, or large-scale system is needed, other equipment groups may also need to be chosen.

Where should backups be stored?

It should be stored outside the Gateway, such as on NAS, Cloud Storage, or a document management system, along with specifying the date and Firmware Version.

Is it necessary to update the firmware every time immediately?

There is no need to rush in the Production system in every case. You should read the Release Note, check Compatibility, back up Configuration, and test at an appropriate time.

Conclusion: The highlight of Fusion is not what becomes faster, but what disappears from the system

After considering the Omada Fusion 2.5G from hardware design, built-in controller, cloud management, multi-WAN, security, VPN to SD-WAN, the most interesting thing is not any particular feature, but the number of things the product helps eliminate from the installation process.

One separate controller is missing. The power cable and Power Adapter are reduced. The initial installation steps are shorter. Device discovery and adoption can be done from the central unit. The touch screen and Cloud Management help reduce on-site inspection work in many situations.

In terms of performance, all five 2.5GbE ports handle NAT at approximately 2.3Gbps and IPS/DPI at over 2Gbps, making the product ready for offices and businesses moving from Gigabit to Multi-Gigabit or Wi-Fi 7 without starting from a gateway that is a bottleneck.

However, Fusion does not replace a separate Gateway and Controller in every system. With a capacity of 30 Omada Devices, the lack of SFP+, the absence of PoE, and the failure domain that combines the Gateway and Controller into a single device are factors that need to be considered according to actual requirements.

For new projects in offices, restaurants, shops, clinics, small hotels, or multi-branch businesses that need a complete Omada system and do not want to add a separate Controller, the Omada Fusion 2.5G Gateway is a very reasonable and attractive option, especially when considering the total cost including hardware, installation time, and system maintenance over the project's lifespan.

Parting Perspective from the SyncTech Solution Engineering Team
A good network device is not measured solely by the number of features, but by how it helps make the system easy to design, easy to maintain, and quick to troubleshoot when issues arise. Fusion 2.5G clearly takes the right path in this regard. The important thing is to choose it in an appropriately sized system and to professionally design VLANs, routing, security, and backup from day one.
