Do you have your vpn configuration in network-manager so that all traffic should go through it, or do you have "Use this connection only for resources on its network" checked? That's in ipv4-settings->routes, same under ipv6-settings.
Also, I assume your /etc/resolv.conf, *after* connecting to the vpn, still has only one "nameserver" entry and pointing at 127.0.1.1? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1704288 Title: Ubuntu 16.04 VPN : DNS information leaking through dnsmasq To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dnsmasq/+bug/1704288/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
