Prestige 791R G.SHDSL Router

4.Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP address to a unique global IP address.

5.Server: This type allows you to specify inside servers of different services behind the NAT to be accessible to the outside world although, it is highly recommended that you use the DMZ port for these servers instead.

Port numbers do not change for One-to-One and Many-to-Many No Overload NAT

mapping types.

The following table summarizes these types.
