DNS servers not correctly set in VPN

view full story

http://askubuntu.com – I have to use an OpenVPN network to work from home, and I occasionally have problems getting DNS to resolve. The problem comes and goes, and I can't reproduce it reliably. I took the OpenVPN config that my employer provided and fed it into the "Import" part of the VPN tab in the Network Manager settings (after installing network-manager-openvpn, of course). The DNS servers automatically provided by the VPN did not appear to work reliably. so I went to the "IPv4 settings" tab of the VPN settings and changed it to "Automatic (VPN) addresses only" and put the search domain and servers in by han (HowTos)
