Try GRC.COM
They have a product called Shields Up that port scans your IP.

thanks

The link is www.grc.com or grc.com.  It is not software that you install, the site scans you from the Internet to see what ports it can see open from the Internet.

To test to see if a port is open, normally you use the application that needs that port.  So I would suggest that you attempt to use iChat.

Typically things like grc.com, and other "port testers and scanners" are you to verify that ports are closed.

From the screen shot I can't tell if you are attempting to allow the traffic out (from you to the Internet) or in (from the Internet to you).

does this only allowing from me to the Internet?

giltjrCommented:
I am not sure.  What is does allow is something that uses source port of 5060 to talk to something that that is listening on any port above 1023.


Typically the rule would be the other way around.  That is anything where the source port is above 1023 can talk to 5060.

Example.  Normal HTTP traffic is source > 1023 and target eq 80.  This is because HTTP (web) servers listen on port 80 and that is the port you are going to.
