Click Configuration > Firewall > Session Control to display the Firewall Session Control
screen. Use this screen to limit the number of concurrent NAT/firewall sessions a client can use. You
can apply a default limit for all users and individual limits for specific users, addresses, or both. The
individual limit takes priority if you apply both.

Summary
This table lists the rules for limiting the number of concurrent sessions hosts can have.
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.
Create rules below to apply other limits for specific users or addresses.
