Joe, I still can't reproduce your issue. Can you please verify against what I'm trying: 1. Setup a VPN that provides DNS via DHCP 2. Connect to that VPN and verify DNS by: $ systemd-resolve --status (...) Link 4 (tun0) (...) DNS Servers: X.X.X.X (...) 3. Disconnect VPN and edit connection: $ nmcli connection edit myvpn nmcli> set ipv4.dns-priority -30 nmcli> save $ nmcli connection show myvpn | grep dns-priority ipv4.dns-priority: -30 ipv6.dns-priority: 0
4. Re-connect to VPN and try to reach a name within the VPN: $ dig some.host.in.my.vpn I have used: $ apt-cache policy network-manager network-manager: Installed: 1.10.6-2ubuntu1.2 Please tell me in which of the steps in your case network-manager behaves differently. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1851407 Title: NetworkManager 1.10.6-2ubuntu1.2 breaks VPN DNS Status in network-manager package in Ubuntu: Confirmed Bug description: NetworkManager as of 1.10.6-2ubuntu1.2 has cause a regression whereby a VPN connection which sets it's dns-priority to a negative value, which should cause the DNS server supplied by the DNS connection to be placed first, instead now refuses to place the DNS server into the resolver under any circumstance. Pinning the 1.10.6-2ubuntu1.1 works around the issue. I suspect the fix-dns-leak-lp1754671.patch has caused this regression. This patch should be reverted as soon as possible to restore proper functionality of network manager with respect to VPN servers with DNS resolvers. $ lsb_release -rd Description: Ubuntu 18.04.3 LTS Release: 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1851407/+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
