Only allow ssh from current subnet

I am a Linux user and very new to OSX. I have an OSX 10.7.5 "Lion" server that I am configuring as a webserver. I only have shell access.

I am tryin to configure the firewall, but ipfw is quite different from iptables. Currently, all ports are open to the world. I would like to add the following rules:

port 80/443: allow incoming connections from any IP address.
anything else: only allow incoming connections from within current subnet.

How would I accomplish this with ipfw?
