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 MAX-207HW2R. 

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.
