I've just set up a firewall for a client using Mandrake 8.2, iptables and 
the gShield firewall tuning script 
(http://muse.linuxmafia.org/gshield.html). It's pretty easy to understand 
and seems to do a good job of covering all the bases, guiding you through 
the setup, etc. It does mention SSH and VPN in there, but I'm not sure if 
it will give you 100% of what you want.

Most of the firewalls I've mucked with have been set up against full 
Internet connections, not wireless AP's. That said, I do intend to set up & 
secure an AP (once I've dug myself out of my current financial hole :) and 
will be trying to use the same set up for that as well (albeit with 
different answers to questions and such :)
