Have configured VPN channel between two servers (1 and 2). This type of VPN is continuously included in some kind of sleep mode until you perform a ping from one server (1) to (2). If you execute ping from server 2 to 1 then the packets are not even as. After activation with 1 to 2 channel what time is and then if there is no traffic, after a while again no longer available to re-ping from the server 1.
Type configure the type of VPN type normally.
Type tell what type of VPN and how he is the type configured to provide the type of logs and the type of configs.
And while your type of question can be seen only incompetence in the type preferences of the type of network type of services. :)
no offense, but really the question is asked in a creepy "gopnicheskaya" style and it does not contain a single drop of the chapeau :D
