Hello All,
I'm currently in the process of setting up a persistent VPN connection from a Server 2003 Machine to an Ubuntu pptpd server. So far everything is working just fine, except for the disconnection after the link has not been used for 2 minutes and 40 seconds.
If the connection is used, it stays up. (I tested this by streaming a video from a share on the remote server. The connection stays up for the entire duration of the video.) Because the connection is marked persistent, Windows server 2003 immediately reconnects,
which is good. Only it takes 12 seconds to re-establish the connection. During the time the connection is down, the routes associated with it are removed. Because the RRAS server also has a default route to a border-gateway and said border gateway routes connections
to the remote subnet back to the RRAS server, there is 12 second period in which there is a routing loop.
I also connected to the VPN server using a Windows 8 client machine. The problem does not occur there. The connection stays alive. This is wat led me to thinking the problem might be on the Windows end.
I cant find anything in the logs, and a wireshark monitoring is not giving me any reason why te connection is terminated.
In RRAS the connection is marked as persistent (as opposed to on-demand), the retry count is set to zero (which is infinite?) and the redial interval is 1 second.
