uverse motorola nvg510- port forwarding DVR not detect
Some time this modem does not detected the DVR connected to it.
The DVR will show up on the device list on the modem but not on the list when doing port forwarding, this can be serious issue.
Few thing can be done to solve this issue. Try running the diagnostics and then restart device. This will most likely solve this issue. If not try restarting you DVR and the modem.
I still does not work try resetting the modem.
