The following table describes the fields in this screen.
8.3 NAT Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
8.3.1 NAT Definitions
Inside/outside denotes where a host is located relative to the ZyXEL Device, for example, the
computers of your subscribers are the inside hosts, while the web servers on the Internet are
the outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for
example, the local address refers to the IP address of a host when the packet is in the local
network, while the global address refers to the IP address of the host when the same packet is
traveling in the WAN side.

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.
