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. Note that port numbers do not change for One-to-one NAT

 

mapping type.

 

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 that previous ZyXEL

 

routers supported only.

 

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

 

local IP addresses to shared global IP addresses.

 

Many-to-Many No Overload: Many-to-Many No Overload mode maps

 

each local IP address to unique global 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 (ILA). Local IP addresses are N/A for

 

Server port mapping.

addresses, then enter 0.0.0.0 as the Local Start IP address and

 

255.255.255.255 as the Local End IP address.

 

This field is N/A for One-to-Oneand Server mapping types.

 

 

Global Start

This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have

IP

a dynamic IP address from your ISP.
