Setup VPN Without Modem In Bridge Mode

@XfinityTony Thank you for your reply.  Yes, I'm definitely aware that running both devices (Xfinity gateway and personal device) both in router mode is not ideal - but I'd also prefer NOT to use a streaming device such as a Roku on my outdoor TV.  Another question for you - if I purchase a MoCA adapter for my personal router, can I run the Xi6 "normally" using MoCA over my personal router, with the Xfinity gateway in bridge mode?  Would I need my own MoCA adapters anywhere else (such as on my other cable TV boxes) in order to make this work?

No problem at all @Techie9!  Wea re always glad to assist to ensure you are receiving the best experience with your service.  Purchasing the adapter can help with your connection, all depends on the equipment you are using in conjunction with that device.  I see that you are using both Xfinity leased equipment along with a store purchased personal device.  My question to you is, have you ensured that your personal device is on our certified modem list?  You can always double check here (https://comca.st/2WQnbnT) to ensure that you are using the best personal equipment to get the most out of your connection.  

Also, have you considered our xFi pods?  xFi Pods are easy-to-install devices that can be paired with a compatible xFi Gateway to help eliminate areas where WiFi coverage drops or is weak, also known as "dead spots."

xFi Pods help extend the range of the WiFi coverage in the home, but are not intended to provide the maximum speed of the Internet speed tier throughout the home. 2nd Generation Pods (XE2) have a maximum throughput of 500 Mbps and 1st Generation Pods (XE1) have a maximum throughput of 200 Mbps over a WiFi connection.

@XfinityArmand This didn't answer my question at all and contains inaccurate information. Can you please read the posts from the top and advise?

@Techie9

This is a great question. For starters, when the technician installed services originally, there should be a MoCa filter already installed. Regardless, the Xi6 and the Xi5 wireless boxes don’t run off of a MoCa connection and simply need the wireless connection. You should be fine to simply run the Xi6 as long as it is getting a wireless signal through a XB3/XB6/XB7 modem. Does this help to clarify what configuration you need to set that up?

@XfinityDevinC Thank you for replying!  So if I'm reading this correctly, I can put my Xfinity gateway into bridge mode and still be able to use by Xi6 wirless box normally?  My understanding is that the Xi6 required MoCa and MoCa was disabled when an Xfinity gateway is put into bridge mode.  If this is not the case and I can run my Xi6 off of my Xfinity gateway in bridge mode, then my problem is solved.
