Port Forwarding - Generally forwarding is done so the outside world can connect to some type of server that is located behind your router/firewall. Web servers, ftp servers, mail servers, computers running telnet, ssh, remote desktop, sql, and mysql are all examples where forwarding would be needed. If you are trying to forward the same application to two different ip addresses, you may have problems. There may be a way around it, refer to the software manufactures homepage for more information.
