You setup port forwarding on your each NAT's to the server behind the NAT..

If you don't have a static IP or resolvable DNS name on one of the boxes you can get it to register with the remote side.. You will have to have the NAT's public IP on at least one side static or resolvable through some form of DNS or DDNS..

Later..
