limit
Select this check box to control the number of concurrent sessions hosts can have.
IPv4 / IPv6 Rule
Summary
The IPv4 rules apply to IPv4 sessions. The IPv6 rules apply to IPv6 sessions.
Default Session
per Host
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.
