Publish/Subscribe problem over internet

I got a server setup with Tomcat and OpenJMS on a
win2000 machine. I setup the openjms config file to
use HTTP, TCP and RMI. Downloaded a sample chat
program which publishes and subscribes to the same
topic to get the desired effect. I played around with
it and finally got it working on the localhost where
the server is running. Awesome! 

Then I decided to try this over the internet using my
work computer as the client and home computer as the
server. 
WC=work computer (client)
HC=home computer (server)
Router=a router which has NAT capabilities

WC <-> Router <-> internet <-> Router <-> HC

When I ran the chat program from a DOS prompt (as it
only runs in command line mode), it started normally
and waited for user input. When typed something in and
pressed return, the openjms server dumped a
JMSException exception in the tomcat log file. I
examine it and basically said it couldn't connect to
the client. It included the clients IP address and
port. When I looked at the IP address, it is the
internal IP address of the client behind it's NAT...
thus it was trying to the connect to the client using
192.168.219.x:port. 

I don't know if the problem lies with the server
configuration or the source code of the chat program
but if anyone could direct me in the right direction,
it would be appreciated!
