What is the behavior of MoCA devices when using Bridge mode on the modem?

Hi, I recently got a new Xfinity One modem and it supports MoCA.  I enabled it and was able to connect through the use of an adapter.  I however had problems because the modem was serving addresses in the 10.x.x.x address domain and I run my own router in the 192.168.x.x address domain. I did not want to change the configuration of my network so I reconfigured the Modem to operate in "Bridged" mode. My understanding was that in this mode, it would take any DHCP requests and pass them to the router. However this does not appear to be the case. The address I now see is 169.254.x.x which is indicative of an unconfigured device. My question is what happens to your embedded MoCA when running in bridge mode? I am assuming that the sequece of events goes: 

   DHCP request->ethernet--->moca_adaptor-->modem-embedded-service->bridge->router;

and for the return trip:

router->bridge->embede Moca service->moca_adapter->ethernet->host requsting DHCP

 

But from the results I am getting from my moca adapters, there is something broken in the chain. 

Thank in advance.
