Chapter 8 Network Address Translation (NAT) Screens
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.
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 address mapping rules move up by one when you take this action.
