DESCRIPTION
MAX NAT
Session Per Host
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.
