My M4 deco had to be reset (red light). After I reset it, I updated the firmware.  Then I added my port forwarding information for a gate controlled that I want forwarded.  I rebooted the M4 deco but the port isn't opening.  I'm checking with Canyoume.org and it's not working.  When I set port forwarding a year ago it was straight forward and worked right away.  For some reason it won't work now.  Is it the new firmware that's causing the issue?  It shows the port should be forwarded in the settings.
