SVN3000 set the “dialogue overtime time” more than 2 hours of the virtual gateway. The client start the network expand, but didn’t visit the internal network, about 2hours, the client may receive the cue that the network expand has been cut
For the independency client end, the client end will re-connect automatically. For the web page client, they need click the “start” button in the web when they want to visit the internal network source.
After the client start the network extender, a TCP connection between the client and the virtual gateway has been created. If no messages transferred by this connection, according to the TCP protocol, this idlesse connection will be cut. So the client receive the clue that network extender has been cut.
