Then you need to figure out what process is keeping us from binding the to interface:

Try switching the connection first manually and then running the
"executing ..." commands manually (below the icd2 dbus error message [which is just complaint about the interface missing introspection data])

Then before the dnsmasq command see what processes are listening and where "netstat -lnp" should give a list, port 53 is the one we're mostly interested in.
