Check for open outbound ports

How can I check which outbound ports are open on my firewall without accessing the firewalls OS.  I can use "telnet IP address port number" to access an active outbound port.  But I need to check avaliable outbound ports that could be used in the future.

I hope this makes sense.

Thanks

Hi Brian,

you can use 'nmap' to scan your fix to find the open ports.
here is the info and the link:
---------
Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or security auditing.

http://nmap.org/
---------

hope it helps.
