Saying "there's a leak" doesn't mean anything. What makes you think it's the case? What are you looking at to tell it's the case?
Please show the data you're using, preferably with something that looks like an IP address (even if it's not the exact thing in your configuration, it should make sense -- we need to see that the value is the same as what is in logs, etc.) Additionally, please make sure you include the logs at least from NetworkManager (/var/log/syslog), preferably the whole syslog as things like what dnsmasq says are also relevant. Also, please try to kill -USR1 the dnsmasq process: sudo pkill -USR1 -c -e dnsmasq Then include here what gets written by dnsmasq to /var/log/syslog, both before connecting to the VPN, and after connecting to it. We need to see what nameservers are used on and off the VPN to be able to tell at all if some requests are sent to the wrong server. ** Changed in: openvpn (Ubuntu) Status: New => Incomplete ** Changed in: openvpn (Ubuntu) Assignee: (unassigned) => Mathieu Trudel-Lapierre (cyphermox) ** Changed in: openvpn (Ubuntu) Milestone: None => ubuntu-17.03 ** Changed in: openvpn (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652525 Title: DNS leak in ubuntu 16.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openvpn/+bug/1652525/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
