DESCRIPTION

 

Global End IP

This is the ending Inside Global IP Address (IGA). This field is N/A for

 

 

One-to-one,Many-to-One and Server mapping types.

 

 

 

 

Type

1-1: One-to-one mode maps one local IP address to one global IP

 

 

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

 

 

mapping type.

 

 

M-1: 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.

 

 

M-M Ov (Overload): Many-to-Many Overload mode maps multiple local

 

 

IP addresses to shared global IP addresses.

 

 

MM No (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.
