I'm having somewhat of a difficulty understanding the difference between point to point, point to multipoint and bridges. What I have is a wireless router on one side of the office, and one wireless router on the other side of the office. One of them is a linksys G router, the other is a linux box with an Atheros G card. What I want is to get the linux box to connect wirelessly to the Linksys and then act as a bridge to it's RJ45 ports.

In my mind I see this working as follows: Set the linksys up as normal. Assign the linux box the proper essid to connect to and MAC address. So far this works, I've test it by assigning an IP and pinging the linksys box. Then set the IP 0.0.0.0 and create a bridge of br0 add the interfaces ath0 (atheros card) and eth0 (local lan port) to br0. Ifconfig all the interfaces up, including the br0 and BAM insta-bridge. But this doesnt work.

What is about this setup that's incorrect?
