port scan software

anyone know of a legit tool or website i can use against my firewall to check for open ports?

(admins, if i cant post this kind of stuff let me know)

 

If I remember it correctly F-Secures free scanner will do that also. Further more it checks all other security related issues: http://support.f-secure.com/enu/home/onlineservices/fshc.shtml
Windows Live OneCare safety scanner will also do that if you go for a full scan: http://onecare.live.com/site/en-US/default.htm
