vpnc resolvconf breaks DNS records

Question

I have Ubuntu 11.04, Network Manager + vpnc + resolvconf. I have some VPN and wired connections configured in Network Manager.

Whenever I connect to the VPN my /etc/resolv.conf gets populated with the VPN's DNS nameservers in front of the eth0 record. However after five minutes or so, the eth0 connection's nameserver becomes first in the list.

How can I disable this kind of behavior?

Answer 1

Add the following to your vpnc config (if using the command line, edit it through the gui for Network Manager)

DNSUpdate no
