After having issues with the LTE-Connection on several RUT950 devices I upgraded the firmware to version RUT9XXX_R_00.06.03.2.
This fixed the issue but I have now another issue:
somehow my port forward rules do not persist after every reboot. If I go to the menu firewall->port foward and press "save" my rules function immediatly. But if I reboot the device, the rules do not function anymore. Is there another way to check if the port forward rules are persistent?
Thank you for your help
