I can ping the gateway machine, and even ping the local ISP. I can also use gftp to access some anonymous ftp sites (such as FreeBSD.org) though performance seems slow.

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).

Sounds like they may be using a proxy server.  IIRC, most fairly recent 
versions of IE can locate a proxy without configuration (assuming it's a 
Windows/MS proxy server)- not sure if that's the default configuration 
for IE or not, but sounds like it's worth looking into- check out the 
existing IE configuration and ensure No Proxy is selected, close IE and 
relaunch- is it still able to reach outside the LAN?
