I have XP Pro connected via a wired/wireless router to ADSL. I'm keen to experiment with port forwarding so I could enlist of a friend who has a similar setup. The problems are that he lives 200 miles away and he isn't computer literate so he would be unable/unwilling to tweak with his system following my instructions by telephone.

A solution would be to have the two ADSL routers in the same room, each with a PC attached to it. Is there some way to connect the two routers together via a cable as if they were both connected to the internet and communicating in the conventional way? What I'd like to do is use PC1/Router1 to connect to PC2/Router2 and have Router2 to forward traffic to a specific Port of PC2. If I have everything in one room, I'm happy to tweak the settings myself, rather than have to persuade my friend to follow my instructions or have a round trip of 400 miles to change the settings myself.

Thanks in advance.
