Netgraph -- I love it's power, but the documentation is frustratingly sparse
regarding certain fundamental concepts.

I will give ng_vlan a brief try later this week when I have some free time to
experiment.  Do you know if I can attach services and assign an IP to the
virtual interface created by ng_vlan?  For some context, my server is receiving
traffic tagged with VLAN 0.  Services on that interface (e.g., dhcp client)
don't appear to recognize the traffic because it is tagged as vlan 0 (versus
being not tagged at all).  So I'm trying to create an interface assigned to
vlan 0 so that I my services on that interface will work.  Think ng_vlan can
help me do that?


For some context these links describe my problem and a Linux solution to it:

I'm trying to create a FreeBSD equivalent solution.  I've already successfully
duplicated the functionality of ebtables using Netgraph.  I'm just stuck at the
last part because I can't assign vlan 0 to an interface (or create a virtual
interface on vlan 0) to which I can move my services (e.g., DHCP client).

Thanks.
