I have a server firewall we developed using RHL Fedora Core 3. It protects our servers and also itself (since the server also serves as a PHP web server). Our workstations are on a separate network, and I wanted to know what port scanner software (free, and windows application) or tests I can do to ensure the firewall is indeed protecting our servers from DoS and whatnot.
