This is a problem that I have experienced since Ubuntu 11.04 (I don't think I used a VPN with 10.10, can't remember). I posted here (post #9) in September 2011: http://ubuntuforums.org/showthread.php?t=1692353
I'm having the exact same problem with Ubuntu 12.04 - I can connect, the connection will stay up and work for a while, then it will disconnect at a seemingly random period (usually within a 10 minute timeframe). I'm having to use Windows 7 on the same computer (dual boot) to establish reliable PPTP VPN connections that stay up. This is one of the main reasons I can't ditch Windows completely. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991666 Title: VPN Connects Successfully & Then Shortly Thereafter Fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-applet/+bug/991666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
