Ports Blocked, Advanced Security Stuck
Good afternoon,
I have a generator with a Mobile Link WIFI device connected, the device requires communication with ports 8080, 8081, 443, 123 and 53. The Mobile Link device only works on 2.4ghz and I have a WIFI extender connected but port test show all 5 ports to be blocked by my Wireless network.
I have Comcast/ xFinity Gateway (Cisco DPC3941T) and i have been using the my xFinity website to try to resolve the issue. I am also working with a technical support person from Generac Mobile Link Support since my attempts to get assistance from Comcast were denied. We have made several attempts to resolve the issue including port forwarding but the Advanced Security option is grayed out and has been stuck in TURNING ON wait 10 minutes for months. I only noticed it during my conversation with the Mobile Link Tech Support. Comcast didn't even attempt to troubleshoot the issue and that is very frustrating for me.
We have attempted everything i can think of and have reset the gateway and have not seen a change in the Advanced Security functionality. I have searched and found other posts from 6-12 months ago, and before i call Comcast to have my device replaced, I wanted to verify there wasn't something more i should do first.
PLEASE I really want to be able to monitor my generator and i can't until i get these ports opened.
Thanks
Scott K.

It's not about your issue, but....
That sounds like an incredibly poorly designed app if you are required to blow holes in your firewall for it. I could seeing it being OK if your trademarked Mobile Link device contacted a central server with encryption, then you connect to the central server with your phone. It's always still sketchy just due to cloud and phone security issues.
When you do get your gateway replaced, or buy a 3rd party one, consider running openvpn.net or wireguard.com on a box on your network. Then you VPN in, and can check on the generator. Both are free. I'd trust running the server software myself more than the folks who put that on the market and told you point the world at their device.

Hello @user_e23d3b! If you haven't already replaced your equipment we would be happy to help in any way we can. To confirm, does this link have the information you wanted or do we need to dig in a little deeper?
