while a hardware firewall is a useful thing, i wouldn't say it
elimintes the need to run firewalls on each of your systems.  If one
computer gets infected with something that wants to propagate on the
LAN, you could be in trouble.

And there are things that external firewalls probably can't catch,
like malware embedded in javascript in a web page.

Anyway: hardware firewall is good, hardware firewall + individual
software firewalls on each host is better.

hth,
