Default Session per
Host
This field is configurable only when you enable session limit.
Use this field to set a common limit to the number of concurrent NAT/firewall 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.
