11.9 Technical Reference

This part contains more information regarding NAT.

11.9.1 NAT Definitions

Inside/outside denotes where a host is located relative to the VMG, 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 limit to the number of concurrent NAT sessions each client host 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.
