==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.


===Using a Static IP===
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.
<li style="color: red;">'''Note: Just if you want to use a Static IP, see the instructions below.'''</li>


'''Static IP need to be set as router’s WAN IP.'''
===DHCP===
Static IP should be in the same subnet as gateway’s LAN interface.<br>
----
For example: if gateway’s LAN subnet is 192.168.10.1, then router’s WAN IP could be for example '''192.168.10.125'''</div>
Using the arrow keys on your keyboard, navigate and find <i>config interface 'lan_wan'</i> erase the current configuration and write these options:  
[[File:LANASWAN04.jpg|border|class=tlt-border]]


==CLI/SSH Router configuration==
option proto 'dhcp'
For the next part you will be configuring router via SSH. For this you need to use the command line interface (CLI) or a SSH software if you’re using Windows or iOS. In this example software '''“putty”''' will be used. Open “putty” enter routers LAN IP address and press '''“Open”'''.<br>
option ifname 'eth0.1'
[[File:LANASWAN005.jpg|border|class=tlt-border]]
option backup '1'
option metric '10'
 
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_4_v1.png]]


After clicking '''“Open”''' you will need to enter router credentials.
===Static IP===
<li>Login as: '''root'''</li>
----
<li>Password: routers admin password (by default admin01)</li>
Using arrows navigate and find <i>config interface 'lan_wan'</i> leave the current configuration and add these four options:
[[File:LANASWAN06.jpg|border|class=tlt-border]]
<br>


Now when you are connected you will need to make changes to network settings, this will be
option gateway '192.168.10.1'
achieved via SSH command: '''vi''', which allows you to edit settings in the router. Enter following
option dns '8.8.8.8'
command in SSH:
option backup '1'
option metric '10'


<li>vi /etc/config/network press latter '''i''' to be able to edit.</li>
[[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:


Using arrows navigate and find '''config interface 'lan_wan'''' and add two options:
/etc/init.d/network restart
<li>1. option gateway ‘192.168.10.1’</li>
<li>2. option dns ‘8.8.8.8’</li>
<li>option backup '1'</li>
<li>option metric '10'</li>
[[File:LANASWAN006.jpg|border|class=tlt-border]]
<br>


Press '''Esc''' and write ''':wq'''.
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:
After that you will need to restart network service on the router, for this use command:
<li>'''/etc/init.d/network restart'''</li><br>
[[File:LANASWAN007.jpg|border|class=tlt-border]]
<br>


After restart is completed go back to routers WebUI and navigate to '''Network -> Firewall -> General Settings'''.
<ul>
    <li><b>Default forwarding action</b>: accept</li>
    <li><b>Masquerading</b>: on</li>
    <li><b>Save</b> changes</li>
</ul>


Scroll down, in '''Zone Forwarding''' find source zone '''lan_wan''' and change “Default forwarding action” from '''reject''' to '''accept''' and also check '''Masquerading''' and save settings.<br>

==Testing the configuration==
==Testing the configuration==
If you did the steps in the right way, your end device should have internet connection according the scheme.<br>
If you did the steps in the right way, your end device should have internet connection according the scheme.<br>
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>
