Can someone please tell me if there is a way to scan a PIX firewall for open ports.  Can this be done from an external location (PC, router, etc)?  Can it be done from inside the PIX?  I'm trying to verify the commands I put into the PIX to open certain ports actually opened the ports.

Thanks!!!

From a client inside the PIX, go to http://www.grc.com
Run Shield's UP to test your protection..

At the same site, there is an option for User Specified Custom Port Probe.
Use this to specify the port range..up to 65535..

Oh . . . duh.  I guess it helps when you look at the page.  :)

Quick question, if you don't mind:  Wouldn't you consider it normal for a PIX to respond in "stealth" mode rather than "closed."  Also, would you consider "stealth" mode to be the better choice of the two?

Thanks!!!!

Yes, I would say that "stealth" is better than "closed"
