Basic info

Adding a WAN port

It is possible to change one of the 4 default LAN ports into a WAN port. The typical disclaimers apply; messing with this stuff could brick your unit.

Preliminary

This procedure was tested using v24-SP2, release 08/07/10 (SVN revision: 14896), with the VPN build.

Facts you should know:

  • eth0 is the interface to access all physical network ports
  • eth1 is the wireless network interface
  • vlan0 is the virtual network device that represents LAN ports. It's "real" device is eth0.
  • vlan1 is the virtual network device that represents WAN ports. It's "real" device is also eth0.

Procedure

  1. Install dd-wrt, turn on the SSH server, and set your public key.
  2. SSH into the router.
  3. Update the boardflags from 0x3658 to 0x3758 (add 0x0100):
root@wli-tx4-g54hp:~# nvram get boardflags
0x3658
root@wli-tx4-g54hp:~# nvram set boardflags="0x3758"
root@wli-tx4-g54hp:~# nvram commit
  1. Adding 0x0100 is necessary because the hardware doesn't have a WAN port and the firmware is initially configured without VLAN support. I tried this because the hardware is basically the same as the WHR-HP-G54, which supports VLANs.
  2. Reboot. After booting, there should now be a "VLAN" tab under "Setup" and there should be two new interfaces in the "Networking" tab: vlan0 and vlan1.
After this point, the remaining steps configure the router to be just like other routers that have a WAN port, with one exception: we map an additional port to the WAN network since there is no WAN port (vlan1).
