Configuration 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/security policy
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.
