Table 133 Menu 15.1.1.1: Address Mapping Rule
FIELD DESCRIPTION
Type Choose the port mapping type from one of the following.
•
One-to-One : One-to-One mode maps one local IP address to one global IP
address. Note that port numbers do not change for One-to-one NAT
mapping type.
• Many-to-One : 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.
• Many-to-Many Overload : Many-to-Many Overload mode maps multiple
local IP addresses to shared global IP addresses.
• Many-to-Many 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.
