[quote=moneymaker]I use a VPN connection on a tablet at work that goes through Verizon and was just wondering why it seems so unstable, seems like I have to relog in several times a day which is a real pain in the arse, especially when I don’t realize the connection has been lost and am unaware that things aren’t happening on the other end. Maybe I just need a VPN monitoring app that flashes the screen when the VPN goes down. There is a little icon in the task bar but I don’t notice right away when the VPN connection is lost.[/quote]
I am assuming that you are refering to going through a cellular network.
If this is the case more than likely the heartbeat of the VPN doesn’t happend frequently enough to keep the data session live. In both EVDO and LTE the data connection to your tablet is not always open and the cell release unused resources. If there isnt enough data passing over the channel while the cell is monitoring the time between requests it will turn down the physical resources (channels, RF power, yada yada). If it is long enough it will release resource and your tunnel might get torn down. I am not sure if you have turn up the reoccurance of th eVPN heartbeat… this might keep your tunnel alive… however if the site is a very busy cell or your time is long enough between request, it is entirely possible that it releasing IP based resources as well which will tear down the logical path as well as the physical.
Releasing the logical resource will kill the tunnel.
What is being release is the difference between a quick connect (which you wouldnt even notice) and a slow connect which you will hate…
Cell phone companys do not want you constantly connected to thier towers for obvious reasons.
