help with Moca VLAn

I have a firewalla gold plus that runs 2 segmented networks.  I also have a 3 device mesh that is in AP mode. The main mesh device has an internet connection and LAN ports.  The other mesh devices have just LAN ports.  I want to run a MOCA backhaul on a separate network so there is less traffic on the backhaul and am confused how to set up the firewalla.  One of the Mocas I can plug into the firewalla to run as a separate network.  But how do I set up the DHCP?  Since the main mesh device accesses the internet thru the Moca, it seems that I would want the address to be the same subnet as the segmented network.  Otherwise it would assign a different subnet to the wireless devices. Can I set up DHCP on hte same subnet as the segmented network so all the devices can communicate with each other?  Or do I need to set up a different subnet and make rules so that all the devices can commicate with each other?  Or do I need to run a VLAN and make the internet connection on the main mesh run on one VLAN and the backhauls on a different VLAN?  It seems that the easiest way would be to put the internet connection on the main mesh on the segmented network and then put the backhaul LAN on the Moca, but I dont have access to the segmented network at that location, just the Moca.

    MocA adapters should be pretty transparent, meaning, they are just like a longer ethernet wire; you should just treat them as is, and provision the unit.

    I also not sure if MoCA can pass VLAN traffic, you will need to look into that.

    I just realized, if all I want to use the moca for is backhaul, I dont think I even need a 4th moca or to connect it up to the firewall.  All I need to do I think is to connect all 3 coax to a splitter.  Is that correct?

    whodiini - your question is timely for me.

    I am on xFinity (Comcast) 1.2Gbps cable. Currently, among 30+ other devices, I have an Apple TV 4k 3rd generation in the living room connected wirelessly to my network and it is behind the Firewalla Gold SE.

    I want to switch the Apple TV over to wired connection via MOCA. My fear is that, since I have the xFinity modem/router/gateway in bridge mode to accommodate the Firewalla, that if I connect the Apple TV via MOCA that I will have no firewall/protection to the Apple TV since the MOCA occurs at the xFinity gateway, outside the Firewalla.

    Is it possible to arrange my network to have full Firewalla protection and also make use of MOCA? If so, can you suggest the connection diagram/settings?

    Thanks in advance.

    [Edit 8/17/24] Another post on the forums indicated to route the ethernet from 1 MoCA to a port on the FW. This precludes using the xFinity XB7 gateway as a MoCA device, so will require a minimum of 2 additional MoCA devices, which I have. If I get it working, I'll come back and update with a diagram and any nuances.

    [Edit 8/18/24] See the crude network diagram below. Is this correct: it's working, is it secure?

    Your MocA 2 need to connect to the switch, I don't think you can connect to the same main home spliter. The MoCA interface is just a simple ethernet bridge, so one side you should have ethernet and the other side ethernet as well.

    Thanks for the comments! The arrangement in the diagram works, functionally.

    I should have been more clear in my question: is the Apple TV a security risk since there is no firewall before it?
