Need a port listen simulator


I am behind a firewall at work (as every is) that not only blocks
incoming requests, but also blocks outgoing request that are not
commonly used ports. I need to find out what ports are available
outgoing but that information is not officially published.

I was wondering if anyone knows of an application that I could install
on my computer at home and have it answer *ALL* port requests so I know
which ones made it out and which ones didn't. Anyone know if something
like that exists?
