11.8 Technical Reference
This part contains more information regarding NAT.
11.8.1 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
Use this field to set a common limit to the number of concurrent NAT sessions all
client computers can have.
If only a few clients use peer to peer applications, you can raise this number to
improve their performance. With heavy peer to peer application use, lower this
number to ensure no single client uses too many of the available NAT sessions.
