Hi Derek, thanks.  Thats actually fairly close to what I am running now
to share my dial-up access across my local LAN.  Its not a firewall, just 
a NAT router but it allows nicely fine-grained control over individual
ports, and protocols as well as ranges of ports.  I currently don't allow
anything to create a connection from outside which saves me a lot of
headaches, :-).  Burns up a lot of log file space on my Redhat server
though.  Distinctly an acceptable trade-off to being cracked however.

This software runs on a standalone system as a DOS program booted under 
MS-W95 (yeah, I know.. ).  But it works.  Its very stable.

I'm hoping to hear what other folks are doing using a more linux based
solution that keeps security intact and still allows decent utilization
of the AT&T broadband speed.

I like your idea of learning a firewall system inside and out.  I almost
always end doing the most fine grained effort due to my nature.
