Network Address Translation (NAT) Screens 8-9
Table 8-6 Address Mapping Rules
LABEL DESCRIPTION
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.
