I am running into a scenario where I need to perform port address redirection for external users accessing an internal VoIP server. Configuring port address redirection is easy enough when you are dealing with one port mapping to one port. But what happens when you need to configure port redirection on a range of ports (say 10000-20000). I obviously cannot configure that many static NAT entries in the router. Anyone know of some creative ways to accomplish this?
Thanks in advance for any help!
