Dual WAN Ethernet ports

Goal

Reconfigure an existing LAN port on the Digi 6350-SR/6355-SR to serve as a WAN interface.

Setup

This article assumes that a second Internet connection is available from an Ethernet cable, and that a primary connection is established via an Ethernet connection in the WAN port. Prior to reconfiguring the LAN port, all interfaces should be operating under default settings, which provide DHCP conenctivity to client devices. For more details on the default settings, see the Default Settings section of the Digi 6350-SR/6355-SR User Manual.

Sample

The sample configuration below shows a Digi 6350-SR/6355-SR with two Internet connections established via Ethernet cables. Ethernet ISP #1 is connected to the reconfigured LAN (port 4) interface, and Ethernet ISP #2 is connected to the WAN Ethernet port.

Note The additional WAN interface can then be used in conjunction with other WAN interfaces when configuring failover, load balancing, or other advanced routing policies.

Sample configuration

Open the configuration profile for the Digi 6350-SR/6355-SR and make the following changes:

  1. In the Network -> Interfaces section, specify a name for the new interface and click Add.
  2. Ensure Enable is selected and adjust the Interface type if necessary.
  3. Specify the Device that should be associated with the new WAN interface. (Per the sample above, this will be LAN 4.)
  4. Set the Zone to External.
  5. In the Network -> Bridges section, expand the LAN entry.
  6. Using the pull-down menu next to the Device indicating LAN 4, select Delete.

The LAN port is now reconfigured to serve as a WAN interface.
