Advanced Routing Technology for the Masses

Ubiquiti Networks introduces the EdgeRouter™ 4, the next generation of router for the EdgeMAX®platform. EdgeRouters combine carrierclass reliability with enterpriselevel features in a compact and affordable unit.

The EdgeRouter 4 offers Gigabit Ethernet ports and an SFP port for a fiber link.

The EdgeRouter 4 is capable of routing up to 3.4 million packets per second and has a line rate of 4 Gbps.

Powered by a proprietary and intuitive graphical interface, EdgeOS®, EdgeRouters can easily be configured for routing, security, and management features required to efficiently run your network. For advanced network professionals, an integrated CLI is available for quick and direct access using familiar commands.

Even greater convenience and flexibility is provided by the UNMS app, which makes it possible to manage the EdgeRouter remotely from your mobile device.

Manage Your Network

DHCP Server
Set up multiple DHCP servers to assign IP ranges in different subnets on the different interfaces.

Easily control dynamic and static IP addressing for your network devices.

Monitoring Tools
Conveniently track network activity and devices from tools such as Ping, Trace, Discover, Packet Capture, and Log Monitor.

Secure Your Network

Firewall Policies
Organize the rules you apply in the order you specify.

Firewall Groups
Apply the policies to groups filtered by IP address, network address, or port number.

NAT Rules
The EdgeRouter changes packet addressing based on your customized source and destination NAT rules.

Direct Traffic Flow

Each port functions as an independent interface.

You can also configure Virtual Local Area Network (VLAN) interfaces for network segmentation.

Configure static routes and dynamic routing protocols to effectively manage the routes used by the EdgeRouter.


Intuitive User Interface

The EdgeRouter provides a graphical user interface designed for convenient setup and control. Accessed via a network port and web browser, the user-friendly interface provides intuitive management with a virtual view of the ports, displaying physical connectivity, speed, and status.

The Dashboard screen displays detailed statistics: IP information, MTU, transmit and receive speeds, and status for each physical and virtual interface

    Exceptional router

    This is a very good router. With the V2 of its software it has a recent version of Debian kernel upon which EdgeOS is built on. The new kernel is extremely efficient. Also, compliments to the Deploydepot for very fast shipping of the item to alleviate downtime of my client. If you need a router to route 1G uplink - this is the least hardware that you need. ER-X is not sufficient.

    ER-4 - excellent product

    Very happy with Product. Only thing that stopped me from giving 5 stars is the SPF performance was slightly less than perfect. IIt's possible that it's the Transceiver that is the issue. I was just slightly below 940Mbps. Normally around 910Mbps. Once I changed my config and used Ethernet, I am continually maxed at 940Mbps. Also I am able to transfer up to 26MB/s over Ipsec vpn tunnel. Very impressed.

    Ubiquiti FTW

    Bought this to replace my ER-Lite as it has double the power, I use many features including QoS, VLANs and IPSecVPN Site-Site tunnels with no issues. Great enterprise features and high-end consumer price!
