DESCRIPTION
Type
Choose the port mapping type from one of the following. 
One-to-One: One-to-One mode maps one local IP address to one global IP 
address.
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 (the SUA Only option). 
Many-to-Many Overload: Many-to-Many Overload mode maps the multiple local 
IP addresses to shared global IP addresses.
Many One-to-One: Many-One-to-One mode maps each local IP address to a 
unique global IP address. 
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.
