Well, in either case, there's going to be #VLAN on the #MoCA network, cause even with the router I will need to get multiple networks to my server.
The question is, will the MoCA endpoints be usable as access ports, or will all devices have to be VLAN aware?
If an ordinary device receives both untagged and tagged frames, what does it do with the tagged frames?
What if I do without the switch though...
From what I can tell, the #MoCA network functions as a switch. And assuming the FTTdp thing just bridges it all through, I'm basically connected to ISP router through a switch. So broadcasts and whatever junk will be sent to the ISP, which will probably drop the #VLAN junk, but the vast majority of the packets won't be sent there. So it'll work...
