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 IAD.
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.
