Ok here I go. I have a step by step guide on how to forward the bittorrent ports (6881-6999) in the Windows XP Firewall which you can find here. If you just follow the steps that are there, you should be fine (I suggest that you only forward ports 6881-6889 because port forwarding in the Windows XP Firewall could take a very long time due to the fact that you have to forward each port one by one. Plus, those where the original ports Bittorrent used untill the later version where the range was extended.) Next for your ZoneAlarm Firewall, I have found another guide on how to forward your ports which you can find here. Its not really an official guide, but if you look at the post made by RES666, you should be fine (Also, the range he has is off, don't use the range he gives you. Use 6881-6999, those are the bittorrent ports). Now, If you could tell me exactly what kind of router you have (D-link, Linksys, etc.) and give me the model number of the router, I can give you a step by step guide on how to forward those ports. Hope I could help.
