This article provides a guide on how to configure the LAN ports as WAN. It can be usefull as wired ISP redundant connection or even to change the port for physical damage or a custom mounting. | This article provides a guide on how to configure the LAN ports as WAN.

==CLI/SSH Router configuration== | |||
The next step of the configuration will be done over SSH/CLI. For this example we'll be using "PuTTY" - a free SSH client that can run on Windows. | |||
Open "PuTTY", enter the router's LAN IP address into the "Host Name (or IP Address)" field and click 'Open'. | |||
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_8_v1.png]] | |||
Next, enter the login credentials: | |||
login as: <b>root</b> | |||
[email protected]'s password: <b><admin_password></b> | |||
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_9_v1.png]] | |||
Next, we'll have to edit the <b><i>network</i></b> config file using the built-in "vi" text editor. To begin editing the <i>network</i> config file: | |||
vi /etc/config/network | |||
Then hit the "I" key on your keyboard to enable editing. | |||
There are two distinct configurations described below. One is a [[#Static_IP|static IP]] configuration for setting the new WAN port manually, the other is [[#DHCP|DHCP]] - for automatic network configuration of the new WAN port. Follow only the instruction that suits your needs. | |||
===DHCP=== | |||
---- | |||
Using the arrow keys on your keyboard, navigate and find <i>config interface 'lan_wan'</i> erase the current configuration and write these options: | |||
option proto 'dhcp' | |||
option ifname 'eth0.1' | |||
[[File: | option backup '1' | ||
option metric '10' | |||
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_4_v1.png]] | |||
===Static IP=== | |||
< | ---- | ||
Using arrows navigate and find <i>config interface 'lan_wan'</i> leave the current configuration and add these four options: | |||
option gateway '192.168.10.1' | |||
option dns '8.8.8.8' | |||
option backup '1' | |||
option metric '10' | |||
< | [[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_5_v1.png]] | ||
---- | |||
To exit the "vi" editor, press the "Esc" key, type in <i>:wq</i> and hit "Enter". While still on the command line, restart the <i>network</i> service on the router - this will apply the changes made to the configuration. Use this command: | |||
/etc/init.d/network restart | |||
Next go back to the WebUI and navigate to <i>Network → Firewall → <b>General Settings</b></i> page. Scroll down to the "Zone Forwarding" section to find source zone 'lan_wan' and change the following: | |||
< | |||
<ul> | |||
<li><b>Default forwarding action</b>: accept</li> | |||
<li><b>Masquerading</b>: on</li> | |||
<li><b>Save</b> changes</li> | |||
</ul> | |||

Go to '''Network --> WAN''' and check if the new LAN_WAN is enable and if it has an assigned IP. | |||
<li>Set up your WAN as a main connection</li> | |||
<li>Set up your configured LAN port as WAN failover backup.</li> | |||
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_7_v1.png|border|class=tlt-border]]<br> | |||
<li>Go to '''www.whatsmyip.com''' and check your public IP.</li> | |||
[[File:0011.png|border|class=tlt-border|960px]] | |||
<li>After that, unplug the WAN cable and check again your Public IP. Your end device should have internet connection and a differt public IP</li> | |||
[[File:0012.png|border|class=tlt-border|960px]]<br> | |||
<li>So, plug again the WAN internet connection and wait a few seconds. The public IP should change again to the first IP shown.</li> | |||
