Linux Firewalls

[Jeff Welling]

Happy Monday. Sigh.

Anyway, I am in the midst of replacing one of my gateways (failed
hardware) and am just about to go through reinstalling and reconfiguring
all the various programs and services.

I've been using arno-iptables-firewall in the Debian repos, and its done
the job quite nicely, but I wonder if it can be improved upon or superseded.
So I'm wondering, what do other people use for their Linux Firewalling
needs, if you don't mind me asking?

Cheers,
Jeff.
