Max NAT/Firewall 
Session Per User

When computers use peer to peer applications, such as file sharing 
applications, they may use a large number of NAT sessions.

 If you do not 

limit the number of NAT sessions a single client can establish, this can result in all 
of the available NAT sessions being used. In this case, no additional NAT sessions 
can be established, and users may not be able to access the Internet.  

Each NAT session establishes a corresponding firewall session. Use this field to 
limit the number of NAT/firewall sessions each client computer can establish 
through the ZyXEL Device. 

If your network has a small number of clients using peer to peer applications, you 
can raise this number to ensure that their performance is not degraded by the 
number of NAT sessions they can establish. If your network has a large number of 
users using peer to peer applications, you can lower this number to ensure no 
single client is using all of the available NAT sessions.
