I'm not familiar with systemd-resolved but it seems that you are not using it as otherwise you'd have 127.0.0.53 in /etc/resolv.conf?
If you could run a packet capture while you do DNS lookups when connected to the VPN that would be useful. You could capture with: sudo tcpdump -w /tmp/dns.pcap -ni any port 53 Then resolve some queries you expect to be answered by your VPN provided DNSes. After that, please attach the /tmp/dns.pcap in here. FYI, this will show us what you resolved so don't run the capture while you are doing anything private. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685391 Title: DNS leak in Xubuntu 17.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1685391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
