I'll chime in and say I really like Shorewall.  It models one layer 
above iptables, so you think in terms of zones (net, lan, dmz), 
interfaces (eth0 is attached to dmz), policy (deny net to dmz) and rules 
(allow net to dmz: on ports 80 and 443).


Every time I've tried to replace it with something higher up the stack 
(simpler) or lower, I keep returning to it.
