I did some tests, and can confirm that with n-m 1.2.6-0ubuntu0.16.04.1 my local DNS (sent via dhcp to the machine) is also added to the DNS server list when the VPN is established: Aug 31 20:36:32 31-64 dnsmasq[1118]: setting upstream servers from DBus Aug 31 20:36:32 31-64 dnsmasq[1118]: using nameserver 10.0.5.5#53(via ens3) Aug 31 20:36:32 31-64 dnsmasq[1118]: using nameserver 10.172.64.1#53 for domain private Aug 31 20:36:32 31-64 dnsmasq[1118]: using nameserver 10.172.64.1#53 for domain internal (...) The line about using the 10.0.5.5 nameserver does not appear the logs when using n-m 1.2.2. As far as I can see, there are two other bugs filed about this: bug #1671606 DNS server from vpn connection is not being used after network-manager upgrade to 1.2.6-0ubuntu0.16.04.1 bug #1688018 DNS server from vpn connection is not being used after network-manager upgrade to 1.2.6 ** This bug has been marked a duplicate of bug 1688018 DNS server from vpn connection is not being used after network-manager upgrade to 1.2.6 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
