Conclusions:

NAT routers allow you to host server processes, but your router must be informed of the ports on which those processes listen for incoming requests. Only one server process can receive incoming requests addressed to each port on the router. At least four separate mechanisms have become popular for configuring your NAT router in support of your server processes. We sometimes refer to all four of those techniques with the general term - "Port Forwarding". Two of those four mechanisms are so insecure as to invite attack, and their use demands constant vigilance. The other two mechanisms are a little more difficult to configure, but they provide a level of security that is consistent with generally accepted, responsible Internet behavior, so long as the corresponding server processes are well managed.
