XB7 - Offline Devices and Port Forwarding
Recently I upgraded my home’s Comcast Gateway to one of the newest models available in the state of New Mexico, it is a XB7, model number CGM4331COM. It has been working well for TV and Internet and phone calls, but it is still a very frustrating experience when it comes to port management.
I have a number of IP-based security cameras that I need to view “remotely” [when I am not in the presence of my home network]. This ability requires that I port-forward the IP addresses of these cameras within the gateway.
The cameras are working fine when I am at home and they are using either a wireless or wired network connection. However, my gateway lists these cameras as “Offline Devices” despite the fact that they are working perfectly, except for remote viewing. Devices that the gateway recognizes as Offline Devices cannot be added to the list of forwarded ports.
I have restarted the gateway. I have told the gateway to “forget the devices”, and then reinstalled the devices. Neither worked (on multiple occasions) to get the gateway to recognize the cameras as Online Devices.
I need someone at Tech Support to tell me the “magic steps” to make the gateway “recognize” an Offline Device and transition it to an Online Device, so that I can open the ports for “remote viewing”.

No known changes to resolve this problem. Comcast tech support appears to be clueless as to answering this problem.

I have the same problem. Even though my wireless devices are working fine, the gateway says they are offline. My problem is that shared pc's don't show up on the other network pc's. The one solution that works is to restart the Gateway using Xfinity's network app. Everything immediately shows up as online and on all other network pc's. Unfortunately, it only lasts for a few days at a time and I have to restart the Gateway again. The Comcast techs I've dealt with have been clueless about the cause.

Thanks for responding. Recently I used the Xfinity app on my iPhone, and the IP cameras previously show as “Not-Connected” off-line devices were now listed as “Connected”. So, forwarding their ports was simple. Haven’t run across a situation yet where a camera was on-line but shown as “not-connected”. So for now, all is good - but I would still like to know how to manually transition a working but “not-connected” device to connected status.
