The firewall is done, if you download bit tornado and set the ports it uses to 50,000start 60,000 end and set it to pick random ports then go into your router config and forward ports 50,000-60,000 you will be all set, be sure in your router config you forward the ports to the pc you are using BT on, check the tutorial I put this in step by step. As far as the router at work, the http://192.168.1.1 link here is my example for a linksys wireless G router, the config will be diffrent for diffrent brand names, the number I cited was just an example of my linksys wireless g. Tell me what router you have at work and Ill see what I can do.
