With a NAT router, you only have one public IP address, so the server
behind the NAT router appears to the world as the same IP as the public
IP address. To run a server behind a NAT router, open ports must be forwarded
to the server so that incoming requests will get there.

If the NAT router is behind the server, the server is open to the net. Just run services
and they will be accessible. The server would have to run as a router to give the second
router acces to the net.

Regular routing is when each machine has its own public IP address. NAT routing
is to share one IP address among two or more machines.
