I want to design a MoCA distribution network for a condominium building with one head-end at the fiber Internet source and 10 secure cpe locations. Actiontec and other brands appear to offer security when used in pairs, requiring 20 adapters in my application. That is messy and expensive as 11 adapters should be enough. One head end using moca 2.0 or 2.5 offers enough throughput. I'm concerned about security since all cpe's are on the same network. A different vlan at each cpe would solve it, but don't know a moca vendor who has implemented vlans or isolation tags. Is there another security method?
