Port forwarding no longer working

I have had a number of ports forwards for several years and they no longer seem to be working.

I can see the ports setup in the xfi app and see they are forwarded to the correct internal addresses, but the services are not reachable from outside the network. I have verified I can reach these systems internally on my network and they are properly listening to the correct ports.

When I attempt to delete or edit any of the port forwards on the app it gives me an error and tells me to either try again later or reboot my gateway.  I have rebooted my gateway several times, but still am unable to modify any of the port forwarding settings.

Hello @cvraspir, thank you for taking the time to reach out to us on the forums I hope you are doing well! I appreciate you giving us such a detailed message to help us fully understand what is going on it helps a ton.

 

That is certainly quite odd that the ports are entered correctly, but won't function as intended and that you are unable to edit/delete them in the app. We will want to do some troubleshooting on our end to see if we can get this issue corrected for you.

 

Can you send us a private message with your first and last name and address to get started?

I opened a case with support.  The frontline engineer didn't even know they had to configure the settings via the myxFi app.  I believe my case has been escalated, but I have not heard back anything.

I was able to delete all the port forwarding settings I had when I did the factory reset of the modem.  Unfortunately, that means that I have no port forwarding at all and when I try to do add any it tells me to Try again later.

Well after going through another factory reset the issue seems to have been resolved.  It looks like it was having trouble adding at first, but then suddenly it started working again.  Not sure what changed, but so far things are working again after a second full reset of the modem.  Note the second reset I did the hold the WPS button for 60 seconds to reset it and not through the admin page.  Not sure there is a difference, but that was one of note.

I figured this out - any static IP addresses now have to be within the DHCP address range and re-assigned as a reserved IP address on the Router (mine is an Arris available at 10.0.0.1 internally).  Once you have the machine IP address assigned within the DHCP range and set as a reserved IP, you can then use the online Xfinity port forwarding tools to re-create your port forwards.
