I have a WRT-54GL, a Thomson DSL modem/router and a DSL line (PPPoE). I currently connect the Thomson to the internet, and have the WRT between the Thomson and my LAN through its WAN port. However, the Thomson router is crappy and can't even do port forwards correctly.
My question is: (How) can I directly connect the WRT to the internet using the Thomson's modem? I want the WRT to get the external IP and all traffic, so the Thomson does as little work as possible, even just relaying packets, if I can. Otherwise, I can't forward any ports in any way, as the Thomson is broken.
