9.5.1 Configuring Address Mapping

To edit an address mapping rule, select the radio button of a rule and click the Edit button to
display the screen shown next.

Type

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.
2. 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.
3. Many-to-Many Overload mode maps multiple local IP addresses to shared global

IP addresses.
4. Many One-to-One mode maps each local IP address to unique global IP

addresses.
5. Server allows you to specify inside servers of different services behind the NAT to

be accessible to the outside world.
