Do you have your vpn configuration in network-manager so that all traffic should go through it, or do you have "Use this connection only for resources on its network" checked? That's in ipv4-settings->routes, same under ipv6-settings.
Also, I assume your /etc/resolv.conf, *after* connecting to the vpn, still has only one "nameserver" entry and pointing at 127.0.1.1? -- 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/1704288 Title: Ubuntu 16.04 VPN : DNS information leaking through dnsmasq Status in dnsmasq package in Ubuntu: Incomplete Bug description: Hi, After connecting the VPN # killall -USR1 dnsmasq # tail syslog.log ...

The last 192.168.0.254 name server is running on my local router and forward request to my ISP (this is the default name server when VPN is not activated). When I query the DNS, queries are sent to each name server which makes a DNS information leaking to my ISP I validated that by the mean of tcpdump on eth and tun interfaces and also by using that site: https://www.dnsleaktest.com/ I tried to force the VPN DNS server IPs in the VPN configuration (edit Vpn connection -> ipv4 - > Automatic Adresses only ..) but the result is the same. dnsmasq must not have the local DNS present while VPN connection is established.
