12.8.1 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.

LABEL DESCRIPTION
MAX NAT
Session 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.
