DESCRIPTION
The rules configured in this screen apply to this PVC.
Select the rule's index number from the drop-down list box.
Choose the port mapping type from one of the following.
One-to-One: This mode maps one local IP address to one public IP
address. Note that port numbers do not change for one-to-one NAT
mapping type.
Many-to-One: This mode maps multiple local IP addresses to one public
IP address. This is equivalent to the Single IP feature that previous
ZyXEL routers supported only.
Many-to-Many Overload: This mode maps multiple local IP addresses
to shared public IP addresses.
Many-to-Many No Overload: This mode maps each local IP address to
unique public IP addresses.
Server: This type allows you to specify inside servers of different
services behind the NAT to be accessible to the outside world.
This is the starting local IP address. Local IP addresses are N/A for
Server port mapping.
