[Dnsmasq-discuss] Client DHCP Configuration Question

[bad.cow5843 at fastmail.com]

Hi Berto (and Geert)

Thanks for the help. It's useful to know that NM can be configured to adapt its use of dhcp configuration information. I didn't make any changes, but the machine seems to have fixed itself now and both DNS servers are listed when both connections are up, so the problem doesn't show up anymore. Since I won't have access to this machine from today I very probably won't be filing a debian bug.
