Summary

 

 

 

Default Session

Use this field to set a common limit to the number of concurrent NAT/firewall sessions

per Host

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.
