Adding WAN Port to Switch (use as a normal LAN port)

When the WRT is used as an Access Point (AP) or repeater (WDS), the WAN port can easily be configured as a normal LAN port.

Use the following steps:

1.)

Under "Setup" -> "Basic Setup"
Set "Internet Setup" to "Disabled"


2.)

Under "Setup" -> "VLANs"
- Select "LAN" under "Assigned to bridge" for VLAN 1 * This will set the WAN port (vlan1) is part of the LAN bridge (br0). - LaFonera (tested with v.2007-0126): Just set Setup-->Basic Setup-->Internet Setup-->Internet Connection Type to "Disabled" ( Source: [1] (german))


3.)

The VLAN setting should show something like:
             |       Port        |   Assigned
     VLAN    |-------------------|   to bridge
             | W | 1 | 2 | 3 | 4 |
    --------------------------------------------
       0     |   | x | x | x | x |     LAN
    --------------------------------------------
       1     | x |   |   |   |   |     LAN
    --------------------------------------------
       2     |   |   |   |   |   |     None
    --------------------------------------------
      ...
    --------------------------------------------
     Tagged  |   |   |   |   |   |
    ------------------------------

4.)

Save Settings

5.)

Reset the Router
  (See Note)


Note:

  Rebooting the router (Step 5) is not required if you issue
  the following command at a terminal (SSH,Telnet).
  
  However, ONLY issuing the command WITHOUT the steps (1-4)
  above will ONLY last until the next reboot).



Command:
  'brctl addif br0 vlan1'
  I tried above and it didn't worked for me. I attached a device on the WAN-
  port. I pinged this device endlessly and watched it, to see if my changes
  are successful. I realized, that the pings went through after rebooting
  the router. But after a few seconds the device was unreachable again. I
  ssh'd to my router and did a look with '~#ifconfig' for the interfaces and
  saw, that device 'vlan1' was missing. I (re)activated the interface with
  '~#ifconfig vlan1 up' and the pings immediately went through! To
  automatically issue this command after reboot, I did the following on the
  shell of the router:

  ~#nvram set rc_startup='ifconfig vlan1 up'
  ~#nvram commit
  ~#reboot

An alternate method of configuring the WAN port as a 5th LAN port is described HERE


Q. It would be nice to be able to assign different networks to each of the ports.. Is there any work done in this direction?

A. Easy step-by-step instructions for putting port 4 on it's own subnet can be found HERE

--- In v23 SP2 there is a option in Setup -> Basic Setup -> "Assign WAN Port to Switch" - Tick it and re-boot. ---
