Count one vote for SmoothWall (FW on Linux). 20MB bootable CD image, basic functionality up in <20 minutes.
Has VPN capability, caching proxy, IDS, DNS, DHCP, supports a DMZ segment, port forwarding, etc..
Keep in mind that the freeware version is a NATting FW, so only works with a single external IP address.
