You would want do a port scan from the other side of your firewall. nmap is a popular program for this: http://www.insecure.org/nmap/

You can also Google for "linux port scan" to find others.

How can I scan from the outside if I am on the inside ?  

I need to telnet into something and hack back.

I clearly did not explain this very well.  I was distracted at the time.

My home system has one IP and I am behind the firewall.  I need to test the firewall from the "front side" because that is how others are going to test it.

You can start up right here:

https://www.grc.com/x/ne.dll?bh0bkyd2

This will show your open ports.

Next step is to think about needed services. I would keep just sshd open.

But maybe you have your own webserver, p2p software,  mail server...
