Oh boy, well thank you for the information. I looked at my old machine running openshift origin 1.0.7 and it has dnsmasq running on port 53 and things seem to work fine. External traffic routes to my containers running in openshift. Also, I did have my setup running on this new machine for a couple of days and things with dnsmasq running on 53 seemed to work too. Is giving port 53 over to openshift really necessary?
