Max NAT/
Firewall Session
Per User
When computers use peer to peer applications, such as file sharing
applications, they need to establish 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 client computers can
establish through the P-660H-T1v3s.
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 exhausting all of the available NAT sessions.
