That's what I have here (in addition to a Mandrake 10 box).  The FreeBSD box
runs SBBS with an Ethernet interface to my LAN, and it has two Ethernet
interfaces to wireless access points (one Linksys Wireless-G and one Linksys
WAP-11 "B") using cross-over cables.  The 802.11b is "open" to my neighbors,
but it restricted only to http/https traffic using ipfw.  The 802.11g is
restricted by MAC filtering to my own wireless devices around the house.  In
addition, I have squid acting as a "reverse proxy" on the 802.11b so it enables
http traffic based on MAC address of the wireless device, with those MAC
addresses not in the squid.conf being redirected only to an internal website
I've setup (no matter what URL they open).  It's actually allowing all traffic
regardless of MAC address now, but I wanted to test the concept of a reverse
proxy just for grins... kinda like hotels do unless you've "activated" your
account!

The Mandrake box is the DMZ host and catches all traffic not otherwise
redirected at the router, such as redirections to my mail server, ftp server,
etc.  I run squid also on the Mandrake box in accelerator mode.  All incoming
http traffic is redirected to that squid, and based on my split DNS is
distributed to the appropriate internal server/device.  That's why
http://www.bbsdoors.com goes to the FreeBSD apache, http://bbs.filenet.wwiv.net
goes to one of the BBS machines and http://www.landtree.net goes to a wireless
webcam on my bird feeder! :)

Why bother?  It's fun to do!  :)
