On a similar vein, I use pfsense as a Firewall (FreeBSD derivative)

Has many features and Web GUI configuration. Seems to really do the 
trick for me.

I tend to only use the iptables firewall in Centos for host based 
firewalling (basically I only edit the INPUT table), for multi-homed 
dedicated firewalls (i.e. using the FORWARD'ing table) something like 
pfsense really does it nicely.
