    Ok thank you for your help.

    Looked up the DNS domain and that IP address shows different to the one I was using and thought the DVR was. I tried using that for port forwarding but when trying to apply it states 'This IP should be in the same subnet as the LAN IP'

    Looked up the WAN IP of the Orbi as your advice but cant see anything under the Router status settings as you advise and any IP address I can see there does not match the one found against my DNS look up.

     

    This is sounding promising!


    There are two sets of IPs in play here--public WAN addresses and private LAN addresses.

     

    The public WAN IP address of the Orbi router should be shown under the "Internet Satus" display.  See attached screen shot from the user's manual. Your No-IP dynamic DNS must resolve to this WAN IP, or port forwarding will not work. You should also see the same WAN IP if you go to http://www.whatsmyip.org from a device connected to Orbi.

    Your DVR will have a private LAN IP when connected to Orbi, something like 192.168.1.25.  When you setup your forwarding rule, you must reference the private LAN IP of the DVR as the Internal IP address in the forwarding GUI.

     

    It would help if you posted your IP addresses and some screen shots of what you are entering. You can replace part of the WAN IP address for provacy, e.g. 71.23.XX.125.
