- Open the 'Network Connections' folder (click Start, then Control Panel, then Network and Internet Connections, then Network Connections.)
- Click the shared connection or the Internet connection that is protected by Internet Connection Firewall, and then, under Tasks, click Change settings of this connection.
- On the Advanced tab, click Settings.
- For each port you wish to forward, (i.e. 6881, 6882, ... 6889) do the following:
- On the Services tab, click Add and enter all of the following information:
- In Description of service, type an easily recognized name for the service, such as "BitTorrent".
- In Name or IP address of the computer hosting this service on your network, enter 127.0.0.1 (this means "the local machine.")
- In both External and Internal port number for this service, enter the port number, e.g. 6881.
- Select TCP, then OK.
An easier way would be to just install Service Pack 2. Than you'll have the upgraded XP firewall with the controls in the control panel.
