DESCRIPTION
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.
