I am running Ubuntu 16.04.2 LTS and I updated all packages to latest stable version including dnsmasq-base (2.75-1ubuntu0.16.04.2). VPN connection is still not working. Wireshark show that all queries are forwarded to local DNS server instead of one defined by VPN. This is not only information leak bud it also break DNS resolution at all. I am getting "resolve call failed: Query timed out" from systemd-resolve and "no servers could be reached" from host command.
I downgraded network-manager manager again to 1.2.2-0ubuntu0.16.04.4 and it start working fine. Wireshak show that all DNS queries (at least during time i was monitoring it) are forwarded to correct DNS server defined by VPN server. Is there a way how to expedite this ? This bug is affecting lot of users and guys are considering to not stick with Ubuntu as work machine. If there is no clear way how to fix this then please downgrade network- manager and network-manager-gnome back to 1.2.2* version in stable tree. Especially the second one is important as it will resolve problems with GUI and was removed from Ubuntu repository right after update was introduced ... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dnsmasq in Ubuntu. https://bugs.launchpad.net/bugs/1639776 Title: name resolution (dnsmasq) fails to send queries out after suspend/resume reconnects the interface Status in dnsmasq package in Ubuntu: Fix Released Status in network-manager package in Ubuntu: Invalid Status in dnsmasq source package in Xenial: Fix Released Status in network-manager source package in Xenial: Invalid Status in dnsmasq source package in Yakkety: Fix Released Status in network-manager source package in Yakkety: Invalid Status in dnsmasq package in Debian: Fix Released Bug description: [Impact] * suspend/resume (which involves disconnection of network devices) leads to dnsmasq failures.
