>> Many people have run more than one firewall at once without a problem.
However the *risk* of a problem is always there, and that's why it
shouldn't be done.
Here's what Microsoft has to say about running two software firewalls
at once:
http://www.microsoft.com/athome/secu.../firewall.mspx
"Q. Should I use both the built-in firewall and a software firewall
from a different company on my Windows XP computer?
"A. No. Running multiple software firewalls is unnecessary for typical
home computers, home networking, and small-business networking
scenarios. Using two firewalls on the same connection could cause
issues with connectivity to the Internet or other unexpected behavior.
One firewall, whether it is the Windows XP Internet Connection
Firewall or a different software firewall, can provide substantial
protection for your computer."

Do you know of a technical reason for not running two simple packet
filtering f/ws concurrently?
