DESCRIPTION
Type
Choose the IP/port mapping type from one of the following.
One-to-One: This 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: This 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: This mode maps multiple local IP addresses to shared
global IP addresses.
Local Start IP This is the starting local IP address (ILA).
Local End IP
This is the end local IP address (ILA). If your rule is for all local IP
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 not configurable for the One-to-One mapping type.
Global Start
IP
This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have
a dynamic IP address from your ISP.
Global End IP This is the ending global IP address (IGA). This field is not configurable for
One-to-One and Many-to-One mapping types.
Mapping Set
Select the number of the mapping set for which you want to configure.
