Use this screen to limit the number of concurrent NAT sessions a client can use, to ensure that no single
client uses up too many available NAT sessions. Some applications, such as P2P file sharing, demand a
greater number of NAT sessions in order to get a better uploading and downloading rate. Click Network
Setting > NAT > Sessions to display the following screen.
Use the Sessions screen to limit the number of concurrent NAT sessions each client can use. Click
Network Setting > NAT > Sessions to open the Sessions screen.
Note: Enter a number of concurrent NAT sessions in the MAX NAT Session Per Host field, and
click Apply to limit the number of concurrent NAT sessions a client can use. Otherwise,
clear the number in the MAX NAT Session Per Host field. Click Apply and there is no limit
for concurrent NAT sessions a client can use.

LABEL DESCRIPTION
MAX NAT Session Per Host Use this field to set a common limit to the number of concurrent NAT sessions each
client computer can have.
If only a few clients use peer to peer applications, you can raise this number to
improve their performance. With heavy peer to peer application use, lower this
number to ensure no single client uses too many of the available NAT sessions.
