===Using DCHP===

 +
==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===
 
----
 
----
−
Leave the settings as default and click '''save'''<br>
+
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:0004.png|border|class=tlt-border|960px]]
+
 
−
===Using a Static IP===
+
option proto 'dhcp'
 +
option ifname 'eth0.1'
 +
option backup '1'
 +
option metric '10'
 +
 
 +
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_4_v1.png]]
 +
 
 +
===Static IP===
 
----
 
----
−
<li style="color: red;">'''Note: Just if you want to use a Static IP, see the instructions below.'''</li>
+
Using arrows navigate and find <i>config interface 'lan_wan'</i> leave the current configuration and add these four options:
−
'''Static IP need to be set as router’s WAN IP.'''
+
 
−
Static IP should be in the same subnet as gateway’s LAN interface.<br>
+
option gateway '192.168.10.1'
−
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>
+
option dns '8.8.8.8'
−
[[File:0005.png|border|class=tlt-border|960px]]
+
option backup '1'
−
==CLI/SSH Router configuration==
+
option metric '10'
−
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><br>

[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_5_v1.png]]
−
<br><br>
  −
After clicking '''Open''' you will need to enter router credentials.
  −
<li>Login as: '''root'''</li>
  −
<li>Password: routers admin password (by default admin01)</li>
  −
[[File:0007.png]]<br><br>
  −
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:
  −
<li>'''vi /etc/config/network''' press latter '''i''' to be able to edit.</li>
  −
===Using DHCP===
   
----
 
----
−
Using arrows navigate and find '''config interface 'lan_wan'''' and add two options:
+
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:
−
<li>'''option proto 'dhcp''''</li>
+
 
−
<li>'''option ifname 'eth0.1''''</li>
+
/etc/init.d/network restart
−
<li>'''option backup '1''''</li>
+
 
−
<li>'''option metric '10''''</li>
+
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:
−
[[File:0008.png]]<br>
+
 
−
===Using Static IP===
+
<ul>
−
----
+
    <li><b>Default forwarding action</b>: accept</li>
−
Using arrows navigate and find '''config interface 'lan_wan'''' and add two options:  
+
    <li><b>Masquerading</b>: on</li>
−
<li>'''option gateway '192.168.10.1''''</li>
+
    <li><b>Save</b> changes</li>
−
<li>'''option dns '8.8.8.8''''</li>
+
</ul>
−
<li>'''option backup '1''''</li>
+
 
−
<li>'''option metric '10''''</li>
+
[[File:Networking_rutxxx_configuration_examples_use_lan_as_wan_6_v1.png|border|class=tlt-border]]
−
[[File:00008.png]]<br>
+
 
−
Press '''Esc''' and write ''':wq'''.<br>
  −
After that you will need to restart network service on the router, for this use command:
  −
<li>'''/etc/init.d/network restart'''</li><br>
  −
After restart is completed go back to routers WebUI and navigate to '''Network -> Firewall -> General Settings'''.
  −
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>
