It's not just VLANs. Using a switch (as opposed to a hub) will cause the same
problem. Some (managed) switches allow you to put individual ports into the
equivalent of promiscuous mode as well - all traffic on all ports is visible to
the promiscuous port - but if you're using an unmanaged switch you're pretty
much out of luck.
(Perhaps all the above is implicit when you say "VLAN". Just making sure...)
