The following table describes the fields in this screen.

This part contains more information regarding NAT.

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.

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.
