Max NAT/Firewall

When computers use peer to peer applications, such as file sharing

Session Per User

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.
