Mapping Rule

 

 

 

Rule Index

Select the rule’s index number from the drop-down list box.

 

 

Rule Type

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.

 

 

Local Start IP

This is the starting local IP address. Local IP addresses are N/A for

 

Server port mapping.
