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.

Click the delete icon to delete an existing address mapping rule. Note that

subsequent rules move up by one when you take this action.
