On 14.04 experiencing the same problem. After I try to connect to my VPN in a matter of a few seconds after the successful connection I get disconnected. Following this post http://tdanas.blogspot.co.uk/2015/01 /ubuntu-vpn-connects-successfully-and.html I decide to see what are my routing tables while the connection is on. Results are:
Destination Gateway Genmask Flags Metric Ref Use Iface default * 0.0.0.0 U 0 0 0 ppp0 cyrano2.cs.ucl. 172.17.31.1 255.255.255.255 UGH 0 0 0 wlan0 cyrano2.cs.ucl. 172.17.31.1 255.255.255.255 UGH 0 0 0 wlan0 winvpn11.cs.ucl * 255.255.255.255 UH 0 0 0 ppp0 172.17.31.0 * 255.255.255.0 U 9 0 0 wlan0 I do not know how it works but having a duplicate entry in the routing table might be the cause of the problem. -- 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/network-manager-pptp/+bug/991666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
