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.
