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.
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.
