Table 29 Address Mapping Rules (continued)

LABEL

DESCRIPTION

 

 

Type

1-1: One-to-one mode maps one local IP address to one global IP address. Note that

 

port numbers do not change for the One-to-one NAT mapping type.

 

M-1: 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 that previous ZyXEL routers supported only.

 

M-M Ov (Overload): Many-to-Many Overload mode maps multiple local IP addresses

 

to shared global IP addresses.

 

MM No (No Overload): Many-to-Many No Overload mode maps each local IP

 

address to unique global IP addresses.

 

Server: This type allows you to specify inside servers of different services behind the

 

NAT to be accessible to the outside world.
