Just to be sure that I don't have a misconfigured firewall on the FBSD box, I installed FBSD on my laptop, plugged it into a different network - works fine, I can surf the web. Then I plug it into the school's network, and http doesn't work, but ping and ftp can reach the outside world (though again, it's slow).

No a firewall doesn't know anything like that. It makes it choices based
on IP, port and certain flags. There are two posibilties however. The
first is that your DHCP gives you an IP that is blocked by the firewall.
You could check this by using you laptop to steal one of the IP's of a
known working client. The other option is that is a proxy server
installed. That could explain the slow performance. A proxy server
doesn't have the wisdom to block based on that kind of info. (Small
change i am wrong here)

I hope his answers you question. Please do a group reply if you have
more question on this topic and i'll help you if i got the time.
