A port forwarding set is a list of inside (behind NAT
on the LAN) servers, for example, web or FTP,

appear as a single computer to the outside world.

Session Per
User
Use this field to set a common limit to the number of concurrent NAT sessions each client
computer 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.
