Receiving data with Sockets when behind a Router

[Derek Bump]

I'm in need of some guidance.  How do you resolve an IP address when 
it's behind a router or a firewall?

I'm trying to build a simple communications device in Revolution, and I 
have been looking at some of the demo stacks that are out there.  They 
all work wonderfully, but I occasionally run into the problem of being 
behind a Wireless Router.

My IP address when connected through the router is 192.168.0.7, while 
the outside world see my IP as 69.179.91.117.  Attempting to connect to 
the public IP address results in nothing.

I mean I'm figuring with all the Instant Messengers and P2P programs out 
there that there's a way to do this.  Help!
