The ports you need opened depends on what you want to do..
Use MSN Messenger? Yahoo Messenger? AIM? Jabber? Miranda? Trillian? Another
messenger service?
Running a web page?
Using Remote Desktop?
Might use Remote Assistance?
Want to use Automatic Updates?
Have an FTP server?
Want to use Telnet? Secure Telnet?

If you know how to setup VPN or an SSH tunnel, some of this becomes null and
void.
