DESCRIPTION

MAX NAT

Use this field to set a common limit to the number of concurrent NAT

Session

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.

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.
