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:

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:
  
−
vi /etc/config/network

<li>vi /etc/config/network press latter '''i''' to be able to edit.</li>
  
−
Then hit the "I" key on your keyboard to enable editing.

Using arrows navigate and find '''config interface 'lan_wan'''' and add two options:

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.

Press '''Esc''' and write ''':wq'''.
 +
After that you will need to restart network service on the router, for this use command:

option proto 'dhcp'

'''Static IP need to be set as router’s WAN IP.'''
−
option ifname 'eth0.1'

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>

Introduction

The information in this page is updated in accordance with the [[Media:{{{fw_version}}}_WEBUI.bin|{{{fw_version}}}]] firmware version.

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.

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.


Configuration scheme:

WAN TO LANSchem3.jpg

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”.
LAN TO WAN02.jpg
After you clicked “Add New” new configuration window will pop-up, there you leave as default and press “Save”. LANASWAN02.jpg

After saving settings, you will be redirected back to Network -> VLAN -> LAN Network, now you need to open VLAN Network tab in the same window and you will need to:

  • Select VLAN mode: Port based
  • Current LAN interface:
    - Enable wireless access
    - Select your current LAN interface.
    - Turn off LAN port 3 (which will be used as WAN port)
    - Press “Save”.
    • Note: Make sure that you are not connected to that LAN port which you going to disable.
  • New LAN_WAN interface:
    - Click “Add” and new row will appear.
    - Turn off LAN ports 1-2 and leave only LAN port 3 on.
    - Select “lan_wan” in the LAN section and press “Save”.

    • LANASWAN003.jpg

Using DHCP

Leave the setting as default LANASWAN009.jpg

CLI/SSH Router configuration (Static IP)

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”.
LANASWAN005.jpg

After clicking “Open” you will need to enter router credentials.

  • Login as: root
  • Password: routers admin password (by default admin01)

    • LANASWAN06.jpg
    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:

  • vi /etc/config/network press latter i to be able to edit.

    • Using arrows navigate and find config interface 'lan_wan' and add two options:

  • 1. option proto 'dhcp'
  • 2. option ifname 'eth0.1'
  • 3. option backup '1'
  • 4. option metric '10'

    • LANASWAN006.jpg
    Press Esc and write :wq. After that you will need to restart network service on the router, for this use command:

  • /etc/init.d/network restart


    • LANASWAN007.jpg

    Using a Static IP

  • Note: Just if you want to use a Static IP, see the instructions below.

    • Static IP need to be set as router’s WAN IP. Static IP should be in the same subnet as gateway’s LAN interface.
    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

    CLI/SSH Router configuration (Static IP)

    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”.
    LANASWAN005.jpg

    After clicking “Open” you will need to enter router credentials.

  • Login as: root
  • Password: routers admin password (by default admin01)

    • LANASWAN06.jpg
    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:

  • vi /etc/config/network press latter i to be able to edit.

    • Using arrows navigate and find config interface 'lan_wan' and add two options:

  • 1. option gateway ‘192.168.10.1’
  • 2. option dns ‘8.8.8.8’
  • option backup '1'
  • option metric '10'

    • LANASWAN006.jpg
    Press Esc and write :wq. After that you will need to restart network service on the router, for this use command:

  • /etc/init.d/network restart


    • LANASWAN007.jpg
    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.

    Testing the configuration

    If you did the steps in the right way, your end device should have internet connection according the scheme.
