| + | ==CLI/SSH Router configuration== |
| | | |
− | ===Using a Static IP===
| + | 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. |
− | <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.''' | + | Open "PuTTY", enter the router's LAN IP address into the "Host Name (or IP Address)" field and click 'Open'. |
− | 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>

− | 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>
| + | |
− | [[File:LANASWAN005.jpg|border|class=tlt-border]] | + | Next, enter the login credentials: |
| + | |
| + | login as: <b>root</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' |
| + | 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>
