DESCRIPTION
When you select Type you can choose a server mapping set. Choose
the port mapping type from one of the following.
1. 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.
2. Many-to-One: Many-to-One mode maps multiple local IP
addresses to one global IP address. This is equivalent to SUA (in other
words, PAT, or port address translation), ZyXEL's Single User Account
feature.
3. Many-to-Many Ov (Overload): Many-to-Many Overload mode
maps multiple local IP addresses to shared global IP addresses.
4. Many One-to-One: Many One-to-one mode maps each local IP
address to unique global IP addresses.
5. Server: This type allows you to specify inside servers of different
services behind the NAT to be accessible to the outside world.
This is the starting Inside Local IP Address (ILA). Local IP addresses
are N/A for Server port mapping.
This is the end Inside 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 N/A for One-to-One and Server mapping types.
This is the starting Inside Global IP Address (IGA). Enter 0.0.0.0 here
if you have a dynamic IP address from your ISP.
