    Depends on the powerline adapters, not Tomato.

    I understand it depends on the powerline adapter. Is such support standard?

    I bought the product and tested it out. And yes, these powerline adapters support passing VLAN tags.

    Thanks for being the guinea pig! ;)

    Good show. Unless devices are designed really oddly (packet inspection) they should support passing VLAN tagging, since to the device they're just another Ethernet packet. Layer 2 devices shouldn't be particularly complicated.

    FWIW, my sentiments (when I read the initial post) were identical to that of Monk E. Boy. A layer 1 bridge of sorts (that's what I've understood PowerLine adapters to be) shouldn't be manipulating or tinkering with any part of underlying layers (layer 2 in this case, i.e. Ethernet frames utilising 802.1Q).

    However -- and please, someone actually familiar with use of Tomato's VLAN stuff correct me if I'm wrong (it's very likely I am) -- my understanding is that the VLAN firmware builds do not actually use 802.11Q at all.

    The VLAN tagging is 802.1q.
