Type

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 (i.e., PAT, port address translation), 

ZyXEL's Single User Account feature. 
3. Many-to-Many 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.

Local Start IP

This is the starting Inside Local IP Address (ILA). Local IP addresses are N/A for 

Server port mapping.
