The server provides both ipv4 and ipv6 endpoints. Since I have global ipv6 at home, my client defaults to connecting over ipv6. The connection consistently drops after only a few minutes of being connected. If I force the connection to use ipv4 (by hard-coding the host resolution in /etc/hosts), the connection is stable. If I use ipv6 and force proto-tcp=yes, the connection is stable. If I use the default ipv6 and udp, the connection is not stable. Using tcp for VPNs is suboptimal. Hard-coding addresses in /etc/hosts is suboptimal. This may be a bug in openvpn rather than in network-manager-openvpn, but I'm starting here. It's possible there are pathMTU issues involved, but I reproduced this same problem when I was on a different network from my home network (though I did not confirm, when I had access to this other network, that it was ipv6-enabled). I will work on getting more details about both sides of the network to try to debug this. --- ProblemType: Bug ApportVersion: 2.20.10-0ubuntu13 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.10 InstallationDate: Installed on 2010-09-24 (2957 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair Package: network-manager-openvpn 1.8.6-1ubuntu1 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 4.18.0-10.11-generic 4.18.12 Tags: cosmic Uname: Linux 4.18.0-10-generic x86_64 UpgradeStatus: Upgraded to cosmic on 2018-10-18 (11 days ago) UserGroups: adm admin cdrom dialout docker libvirt libvirtd lpadmin lxd mythtv plugdev sambashare sbuild src sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager-openvpn/+bug/1800542/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
