DESCRIPTION
Select this if you want to use port forwarding, trigger ports, or any
of the ALG.
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 WiMAX Modem.
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.
