Well, you haven't quite answered the question. 

You are running shorewall...and your internal IP address is
192.168.2.2.  This is what can be called an RFC-1918 and can't be
directly accessed from the internet.

Can we assume that your system has two interfaces?  One with a
non-RFC-1918 address?

If so...then the best thing you can do is head over to
http://www.shorewall.net/  and go to "Documentation", pick the version
you are running and go to "Index" and then "Port Forwarding" as this
will explain what you need in better words than I could.
