11.4 The DMZ Screen
If you need to allow packets from a specific WAN connection to your local network, NAT supports a
default server IP address. A default server receives packets from the specified WAN connection and
the ports that are not specified in the NAT Port Forwarding Setup screen.
Figure 71 Network Setting > NAT > DMZ
The following table describes the fields in this screen.
11.5 NAT Technical Reference
This chapter contains more information regarding NAT.
11.5.1 NAT Definitions
Inside/outside denotes where a host is located relative to the AMG1302/AMG1202-TSeries, 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.
Note that inside/outside refers to the location of a host, while global/local refers to the IP address
of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in
