Receiving data with Sockets when behind a Router

[Stephen Barncard]

Look at IP tunnelling. This allows a computer on a LAN to get a port 
or range of ports of various protocols through a router from the 
outside world.

All routers will have this.

then one can use dynDNS or other service to get the IP when it 
inevitably will change.
