Firewall Recommendation?

[Valendil]

Well, back again. First question, if I install a firewall on my router (server takes in my cable connection and distributes to other machines on network), will it protect all my networked computers? Or do I have to install the firewall on each machine?

Second, what firewall is free (or reasonably priced) that could be installed on Server 2003? I've noticed a lot of things aren't compatable with 2003 server.

Thanks in advanced

Builtin Windows 2003 firewall in Routing and Remote Access has done the trick for me for quite some time.

The RRAS works as a NAT router and protects all clients.
