Just plug one of the LAN ports into your existing network and leave the WAN unused. Turn off the DHCP server and give the linksys device a proper IP on your network. The stock firmware supports this. This is how I am bridging the wireless linksys network to my wired lan.
It works. ;) Thanks for the tip. Now, when I get my wireless nic tomorrow, I'll see how the wireless part works.
Really? I found that my traffic to the internet wasn't getting routed when I did this. Hmm. I'll have to try again. -- "Curiousity killed the cat, but for a while I was a suspect" -- Steven Wright Security Guru for Hire http://www.lightconsulting.com/~travis/ -><- GPG fingerprint: 9D3F 395A DAC5 5CCC 9066 151D 0A6B 4098 0C55 1484
