I'm using NetworkManager 0.9.8.8 on Arch Linux and hitting a similar problem. It looks like it boils down to a problem with the temporary dnsmasq.conf file NetworkManager writes. I found the file by looking at the arguments passed to dnsmasq:
$ ps -C dnsmasq -ww --no-headers /usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var/run/NetworkManager/dnsmasq.pid --listen-address=127.0.0.1 --conf-file=/var/run/NetworkManager/dnsmasq.conf --cache-size=400 --proxy-dnssec --conf-dir=/etc/NetworkManager/dnsmasq.d $ cat /var/run/NetworkManager/dnsmasq.conf # domains and addresses changed to protect the innocent server=/example.com/10.101.109.80 server=/101.101.10.in-addr.arpa/10.101.109.80 server=/example.com/10.101.109.47 server=/101.101.10.in-addr.arpa/10.101.109.47 server=10.20.248.22 server=10.20.128.83 NetworkManager is prepending /domain/ strings to the returned DNS servers so that they are only used for the local domain. Remaining queries are falling to the bottom two servers, which are the original pre-VPN DNS servers, for which routes no longer exists causing DNS queries to anything other than example.com domain to fail. The file should really look like this: $ cat /var/run/NetworkManager/dnsmasq.conf server=10.101.109.80 server=10.101.109.47 server=10.20.248.22 server=10.20.128.83 Or even better, like this: $ cat /var/run/NetworkManager/dnsmasq.conf server=10.101.109.80 server=10.101.109.47 Manually configuring the DNS servers in NetworkManager results in the following: $ cat /var/run/NetworkManager/dnsmasq.conf server=/101.101.10.in-addr.arpa/10.101.109.80 server=/101.101.10.in-addr.arpa/10.101.109.47 server=10.20.248.22 server=10.20.128.83 This is still wrong. Prepending the domain should only be used when "Use this connection only for resources on its network" is checked.
