[ale] I've hit a rough wall, installin' Smoothwall :-)

I'm glad you're up and running--

For a start, 80/tcp, 443/tcp, and 53/udp are important. That's http,
https, and dns, respectively.

Others will depend on what applications you run and how they access
the net. (Streaming video, ftp, ssh, telnet, etc...)
