I think I might have the same issue. This is the "route -n" output of my computer: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.10.100.3 0.0.0.0 UG 1024 0 0 eth0 10.10.96.0 0.0.0.0 255.255.248.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0
This is the "route -n" output of my computer after connecting to the VPN: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 1024 0 0 vpn0 10.10.96.0 0.0.0.0 255.255.248.0 U 0 0 0 eth0 69.173.118.0 0.0.0.0 255.255.254.0 U 0 0 0 vpn0 69.173.127.3 10.10.100.3 255.255.255.255 UGH 1 0 0 eth0 69.173.127.3 0.0.0.0 255.255.255.255 UH 1024 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 This is the "route -n" output of my computer after disconnecting from the VPN: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.10.100.3 0.0.0.0 UG 1024 0 0 eth0 10.10.96.0 0.0.0.0 255.255.248.0 U 0 0 0 eth0 69.173.127.3 0.0.0.0 255.255.255.255 UH 1024 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 As you can see, after disconnection from the VPN, this extra line remains: 69.173.127.3 0.0.0.0 255.255.255.255 UH 1024 0 0 eth0 Which seems to be what is causing the problem, as it makes it impossible to reach IP address 69.173.127.3 which is exactly the IP address of the VPN server. By manually removing this extra line with the following command: sudo route delete 69.173.127.3 The routing table reverses to its original configuration: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.10.100.3 0.0.0.0 UG 1024 0 0 eth0 10.10.96.0 0.0.0.0 255.255.248.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 And I am now able again to initiate the VPN connection. This issue was not present before upgrading to vivid vervet, so I am not sure what the original behavior in utopic unicorn was. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1423546 Title: [vivid] unable to manage vpn after vpn goes down To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1423546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
