==Introduction==

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

==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.

'''Prerequisites''':
* One RUTxxx series router (excluding [[RUT850]]).
* At least two wired Internet connections.
* An end device for test the configuration.<br>

'''Configuration scheme:'''

==WebUI Router configuration==

Connect to the router’s WebUI navigate to '''Network → VLAN → LAN Network''' and create a new interface by entering name and clicking '''Add New'''.

[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_1_v3.png|border|class=tlt-border]]

After you clicked '''Add New''' new configuration window will pop-up, there you leave as default and press '''Save.'''

[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_2_v1.png|border|class=tlt-border]]

After saving settings, you will be redirected back to '''Network → VLAN → VLAN Networks''', now you need to open VLAN Network tab in the same window and you will need to:

<ul>
    <li>Select VLAN mode: Port based</li>
    <li>Current LAN interface:<br>
- Enable wireless access<br>
- Select your current LAN interface.<br>
- Turn off LAN port 3 <i>(which will be used as WAN port)</i><br>
- Press '''Save'''.</li>
<i><b>Note:</b> Make sure that you are not connected to that LAN port which you going to disable.</i>
    <li>New LAN_WAN interface:<br>
- Click '''Add''' and a new row will appear.<br>
- Turn off LAN ports 1-2 and leave only LAN port 3 on.<br>
- Select your newly created interface in the LAN section and click '''Save'''.</li>
</ul>

==CLI/SSH Router configuration==

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'''.

[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_8_v1.png]]

After clicking '''Open''' you will need to enter router credentials.

</ul>
    <li>Login as: '''root'''</li>
    <li>Password: routers admin password (by default admin01)</li>
</ul>

Now when you are connected you will need to make changes to network settings, this will be achieved via SSH command: '''vi''', which allows you to edit settings in the router. Enter following command in SSH:

<pre>vi /etc/config/network</pre>

Then press the 'I' button on your keyboard to enable editing.

===Using DHCP===
----
Using the arrow keys on your keyboard, navigate and find '''config interface 'lan_wan'''' erase the current configuration and write these options: 

<ul>
    <li><i>option proto 'dhcp'</i></li>
    <li><i>option ifname 'eth0.1'</i></li>
    <li><i>option backup '1'</i></li>
    <li><i>option metric '10'</i><br>[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_4_v1.png]]</li>
    <li>Press the <b>Escape (E<small>SC</small>)</b> button on your keyboard; type <b><i>:wq</i></b> and press <b>Enter</b> to close the editor and save the changes.</li>
    <li>Restart the network service on the router in order to apply the changes by executing this command:<br><pre>/etc/init.d/network restart</pre></li>
</ul>
----
<ul>
    <li>You can exit PuTTY after this return to the WebUI; navigate to the <b>Network → Firewall → General Settings</b> page.</li>
    <li>Scroll down to the <i>Zone Forwarding</i> section, find <i>source zone: <u>lan_wan</u></i>.</li>
    <li>Change <i>Default forwarding action</li> from <b>reject</b> to <b>accept</b>, tick the <b>Masquerading</b> checkbox and save the changes.<br>[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_6_v1.png|border|class=tlt-border]]</li>
</ul>

===Using Static IP===
----
<font size="-1"><u><i>If you're using DHCP, jump to the [[#Testing the configuration|next section of this guide]]</i></u></font>
----
Use the arrow keys to navigate the file and find the <b><i>config interface 'lan_wan'</i></b> section. Add these four options to the configuration: 

<ul>
    <li><i>option gateway '192.168.10.1'</i></li>
    <li><i>option dns '8.8.8.8'</i></li>
    <li><i>option backup '1'</i></li>
    <li><i>option metric '10'</i><br>[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_5_v1.png]]</li>
    <li>Press the <b>Escape (E<small>SC</small>)</b> button on your keyboard; type <b><i>:wq</i></b> and press <b>Enter</b> to close the editor and save the changes.</li>
    <li>Restart the network service on the router in order to apply the changes by executing this command:<br><pre>/etc/init.d/network restart</pre></li>
</ul>
----
<ul>
    <li>You can exit PuTTY after this return to the WebUI; navigate to the <b>Network → Firewall → General Settings</b> page.</li>
    <li>Scroll down to the <i>Zone Forwarding</i> section, find <i>source zone: <u>lan_wan</u></i>.</li>
    <li>Change <i>Default forwarding action</li> from <b>reject</b> to <b>accept</b>, tick the <b>Masquerading</b> checkbox and save the changes.<br>[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_6_v1.png|border|class=tlt-border]]</li>
</ul>

==Testing the configuration==

If everything went well, your device should now have two wired WAN connections. To test this go to the <i>Network → WAN</i> page and check if the new interface is enabled and if it has an IP address.

<ul>
    <li>Set the Wired (WAN) interface as the main WAN connection.</li>
    <li>Set the new interface as WAN failover and save the changes.<br>[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_7_v1.png|border|class=tlt-border]]</li>
    <li>Go to [www.whatsmyip.com] and check your public IP address.<br>[[File:0011.png|border|class=tlt-border|960px]]</li>
    <li>Then unplug the main WAN cable and check again. If the interface failed over correctly, the website should a different IP address than before.<br>[[File:0012.png|border|class=tlt-border|960px]]</li>
    <li>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.</li>
</ul>
