DESCRIPTION

 

 

Type

Choose the port mapping type from one of the following.

 

One-to-One: One-to-One mode maps one local IP address to one global IP

 

address.

 

Many to One: Many-to-One mode maps multiple local IP addresses to one global

 

IP address. This is equivalent to SUA (i.e., PAT, port address translation),

 

ZyXEL’s Single User Account feature (the SUA Only option).

 

Many-to-Many Overload: Many-to-Many Overload mode maps the multiple local

 

IP addresses to shared global IP addresses.

 

Many One-to-One: Many-One-to-One mode maps each local IP address to a

 

unique global IP address.

 

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 Inside Local IP Address (ILA). Local IP addresses are N/A for

 

Server port mapping.
