Hi.
Remember to copy the mailing list too, someone else might be interested
in the future.
Well, there's your problem then, you enable the dhcp package which acts
as a dhcp server and dnsmasq which does so as well, so you can't have
both doing the same job.
So either you just use one by unselecting the other or if you need both
you'll need to tell each other to not meddle with the interface the
other is using via configuration files (interface=xx in dnsmasq.conf,
for dhcp i believe you need an invocation option for that).
My guess is you are trying both to get a result and this happened, and
that you only want dnsmasq around.
Regards.
