Yes my configuration was – internet router to GK-mt1300 AC1300 – GL-MMT1300-37d – that is connecting to the OpenVpn firewall land connecting to it without any issues 00. i see it in their web interface ---- then I have clients contacting to the MMT1300 device without any issues I can connect via webbrowser to the device but it does not go anywhere else from there – everything is staying within that private network
