So what roll over and say we can't use are own router with VM if we have to double NAT then thats that and VM will have to understand we really need modem mode and yes it works on 1Gb but we want more don't we I be happy with 900Mb if VM do that if thats the way its going to be should I need it.
But lets put the real reason VM are doing this and why they are so tight on this is snooped packets being sent out by home routers made to not care about the source IP as it leaves someone infected router as part of a DDoS VM had two options cheap and dirty NAT to which they lock the source IP down or DAI ( Dynamic ARP Inspection) the clean way on the hub to lock the source IP down without NAT
With all and any due that's completely wrong. The devices running in bridge mode would be fine doing source address filtering and even if they weren't there's the BNG on the other side of the PON which will be quite aware of which IP addresses it should be receiving traffic on its subscriber facing interfaces from given it's in the same layer 2 segment and is providing IP addresses.
I'm not sure where you've gotten the idea from that this is why VM don't want modem/bridge mode: it isn't. Nothing to do with DDoS or filtering at all. Everything to do with VM's use of TR-069 and the lack of an IP address on bridge mode PON devices to send TR-069 to. PON devices talk with the OLT over OMCI. VM can't manage their CPE on Nexfibre via OMCI and really like being able to manage their CPE.
