I'm currently using PMfirewall which in turn uses IPchains on my RH 7.1 box.

I dont think any of psionic solutions are actually "firewalls" they are intrusion detection systems. You are looking for things like pmfirewall, or ipchains or iptables, you could also use a script such as this:


(IP tables is required)

Portsentry can be used to make an active firewall. Although it might easily be called an active IDS, as well.

Anyway, if your firewall is a Linux box, use iptables/netfilter. It's not very active on its own, though.
