Over the last years, I've learned that in the end you're almost always 
better off learning the *basic* Linux tools. I admit it's a bit more 
reading first, but then, you're much more comfortable doing what you 
want to do.

In the case of a firewall:

iptables to build your firewall. This isn't black magic. There are many 
good (and many bad :oD) tutorials for iptables on the internet.

And then there's nmap, to check your firewall for what it's worth.

In short: build a wall with (iptables) bricks. And then fire at it with 
an Uzi (nmap) to check if it's solid.

Cheers,
