Hi, I'm having exactly the same problem as described by @raffraffraff - after connection to the VPN the dnsmasq instance handled by NetworkManager no longer makes DNS queries for addresses outside the VPN (eg. google.com) but it can resolve ones internal to the VPN (eg. web- dev.myorg.private).
Using DIG to make a direct DNS query to any remote DNS server works fine, so it looks like dnsmasq has got in a tizz. To add a little more info... I'm able to add a file /etc/NetworkManager/dnsmasq.d/debug containing the line "log-queries" and I can see lines in syslog like: ... dnsmasq[25056]: forwarded www.google.com to 129.215.205.191 So obviously dnsmasq is trying to process the requests but failing. I can also see dnsmasq picking up new configurations from DBUS as I connect/disconnect but there are no errors reported. I also note that dnsmasq is trying to make queries via the public DNS servers, but when connected to the VPN all the queries should go to the trusted DNS server provided on the VPN (this is discussed in bug 1639776) but I think this is a separate issue.

My VPN have a DNS server configured by OpenVPN and config pushed by it while connecting. This server is not registered by dnsmasq so domain names are not resolved but pinging by IP address works. When I test name resolving by pointing to DNS server (172.16.1.1) from VPN provider it's works. For example: $ host google.com 172.16.1.1 Using domain server: Name: 172.16.1.1 Address: 172.16.1.1#53 Aliases: google.com has address 172.217.0.174 google.com has IPv6 address 2607:f8b0:400b:807::200e google.com mail is handled by 30 alt2.aspmx.l.google.com. google.com mail is handled by 20 alt1.aspmx.l.google.com. google.com mail is handled by 40 alt3.aspmx.l.google.com. google.com mail is handled by 10 aspmx.l.google.com. google.com mail is handled by 50 alt4.aspmx.l.google.com. But if I test without pointing DNS server is not working: $ host google.com ;; connection timed out; no servers could be reached My /etc/resolv.conf: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 127.0.1.1 To repair this bug I have to kill dnsmasq and it's automatically reloaded.
