Max NAT/Firewall 

Session Per User

Type a number ranging from 1 to 2048 to limit the number of NAT/firewall sessions 

that a host can create.

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 NBG334W. 
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.
