Hi all,

I have got a WRT54GL, Version 1.1, and after a storm, some LAN ports (1 and 3) and the WAN port seem to be defective (I simply get no link). LAN ports 2 and 4 are still working as a charm (how this can happen beats me ), WiFi is still working, the Webinterface is there, etc. Therefore, it would be great if I could get the router to use one of the LAN ports for WAN instead---one LAN port is enough for me (I'll use a switch anyway), but I'd hate to have to buy a new router...

Is this at all possible? If it is, does anyone by any chance have any pointers on how this could be achieved? I searched the firmware (just upgraded the router to the latest X-Wrt), but I couldn't find anything...

Thanks for any input,
finr.

Yeah, that's possible. It can be configured by changing the vlan0 and vlan1 options in the switch section in /etc/config/network.

Using UCI (example is for a WRT54GL v1.1 and OpenWrt Kamikaze):

uci set network.eth0.vlan0="2 5*"
uci set network.eth0.vlan1="0 5"
uci commit network && reboot

After a reboot LAN (vlan0, eth0.0) is LAN 2 now and WAN (vlan1, eth0.1) is LAN 4.

The mapping is a bit strange, because it's in reverse order

WAN   = Switch port 4
LAN 1 = Switch port 3
LAN 2 = Switch port 2
LAN 3 = Switch port 1
LAN 4 = Switch port 0

Yes, thank you very much, you just saved me 60 bucks !

For some reason the uci settings did not work for me (seems it did not store the changes), but setting the same stuff using the WebIf everything works great .

Thanks again!

You may forgotten to commit the UCI changes with 'uci commit network'.

Hm, no, I double-checked the commands. What was puzzling is that my router doesn't even have a file /etc/config/network. Well, anyway, I'm glad that I was able to revive the router

Just an update, I tried using the UCI commands and fudged it with not using "" quotes on a remote router and had a heck of a time explaining to a non-techy how to put it into fail safe mode (holding reset button for 2 seconds after the DMZ light powers up).

Anyhow, in the latest Kamakazie (7.09) you can edit it in the configuration file /etc/config/network

config switch eth0
        option vlan0    "0 1 2 3 5*"
        option vlan1    "4 5"

much easier then commands.
