How to set Wingate NAT timeout value?

[luozx]

I'm using Wingate 5.2.2, and ENS/NAT, but when I telnet a outside machine, always NAT reach timeout value(may be 30 sec) , and disconnect the session.
How can I set NAT's timeout value?

All other services have timeout setting.

In gatekeeper, in ENS tab you have port security.From the drop down list select the desired route ( Lan connections to internet) and add from port 1 to 65500, or only telnet port, selecting no time out from the options below, on TCP.You may also select UDP.I also had a problem with VPN disconnecting from internal lan and this is the solve.
