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.
Modify Click the edit icon to go to the screen where you can edit the address
mapping rule.

subsequent address mapping rules move up by one when you take this
