LAN as WAN RutOS
This article contains instructions on how to set up LAN port as WAN on RUTxxx if you have a need for multiple wired WAN connections.
Configuration overview and prerequisites
Before we begin, let's overview the configuration that we are attempting to achieve and the prerequisites that make it possible.
- One RUTxxx series router.
- At least two wired Internet connections.
- An end device for test the configuration.
Setting up second WAN interface
To change LAN port purpose to WAN you will have to perform changes in 3 different locations of RUTxxx WebUI
Creating additional VLAN
Go to Network > VLAN section in device WebUI and perform following actions:
- Create new VLAN ID by clicking ADD button.
- On VLAN ID: 1 (LAN interface), select Off from drop-down list, on port that you want to use as secondary WAN.
- On newly created VLAN ID (3 in this example), from drop-down list, select Untagged, on same port.
- After performing these actions press Save & Apply in VLAN settings.
Add new WAN interface
Go to Network > Interfaces WebUI section.
- Enter new Interface Name.
- Click on Add button.
After doing that you will be redirected to new window to set up new interface, when there:
- Choose DHCP Protocol from drop-down list.

Check new WAN interface
Testing the configuration
Your device should now have two wired WAN connections.
- Set the Wired (WAN) interface as the main WAN connection.
- Set the new interface as WAN failover and save the changes.
- Go to [www.whatsmyip.com] and check your public IP address.
- Then unplug the main WAN cable and check again. If the interface failed over correctly, the website should show a different IP address than before.
- Plug the main WAN cable back in and wait a bit. Refresh the website; the IP should have change back to the one shown in the first place.
