What you need is to look at port forwarding/port triggering on the LAN the server is connected to.
What port forwarding does is when a connection attempt is made to a specific port on the public IP of the LAN the server is on the connection request get forwarded to the server, the forwarding has to be put into any modem and routers that is between the public connection and the server. The client MUST specify the public IP of the LAN the server is on NOT the servers local IP address.

Solution 2

Take a look at MSMQ.
.Net API[^]
C/C++ API[^]

Otherwise you can always create your own communication system using the Windows Socket 2 API[^]

Or use Windows Communication Foundation[^]

Solution 4

To amplify Rod and Emilio's answers a bit, do a search for some combination of "NAT", "port forwarding" and "IP address sharing". Your problem isn't uncommon and there a lot of networking admins that understand this stuff far better than most developers do.

Cheers,

Ash
