DNS problems with vpnc and Network Manager

If you are using vpnc to connect to VPN and using Network Manager to manage your network

sudo apt install vpnc
sudo vpnc-connect vpnserver

After succesful connection with vpnc nslookup works fine but ping not.

zajc@comp:~$ nslookup computer
Server:        127.0.1.1
Address:    127.0.1.1#53


Name:   computer
Address: 172.16.1.150

zajc@comp:~$ ping computer
ping: computer: Name or service not known

The workaround is to disable the local forwarding nameserver by commenting out the line "dns=dnsmasq" in /etc/NetworkManager/NetworkManager.conf.

[main]plugins=ifupdown,keyfile,ofono
#dns=dnsmasq
