This part contains more information regarding NAT.
8.8.1 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.
Table 35 Network Settings > NAT > Sessions
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.
