Thanks, I do not like to modify stubs - here is a method that should work: there is a /etc/zentyal/samba.conf with "listen" and "listen_external" directives.. so setting the vlans as "external" and setting "listen_external=no" should work, not sure what else this means for zentyal behavior thou... not sure how to use the "listen" as there also seems to be only "yes,no" - not sure what this is for setting listen to no would cause most of the zentyal functions to be useless right?
