I'm not sure if the latest has all the features OP is seeking, but I've
been using IPCop for ages with NP (which means I've not really visited
the site and browsed as I should). It has a decent Web interface for
administration, ability to block ports, custom Iptables rules inclusion
support, squid proxy capability, etc. Has Green/Red/Blue/Orange zone
support. I've run it on my old Pentium 200MHz with 96MB and got
900MB/sec from good sites through my Road Runner turbo link (w/10/100 Mb
nics). With 2xGB nics on an AMD K7 @ 360MHz, 1.2MB/sec.

Easy install, administration and upgrade path. Biggest weakness is that
docs seem to lag severly sometimes.

And it's FREE open source based on LFS (2.4 kernels?). Find it here.
