    The issue sounds a lot like the ISP device changed from being "only a router" to a combination "modem/router".

    When the Orbi is given a WAN IP address starting with 192.168.1, it automatically switches the IP subnet on the LAN side of the Orbi to 10.0.0.x  In a "Double NAT" situation, Orbi can forward all the ports it wants to, but the connections will never reach the Orbi because the ISP router will block them. See https://kb.netgear.com/30186/What-is-Double-NAT 

     

    There are two recommended solutions:

    1. Place the ISP device into "modem only" or "bridge" mode.  This will leave the Orbi as the only router and port forwarding will work again.
    2. Place the Orbi into Access Point mode and set up port forwarding on the ISP router.  Most routers have basically the same capabilities, so most routers can do this.

    My own choice would be #1.

Thanks for the timely reply! What would be the easiest way to access the ISP router's interface? The adress I used previously does not seem to work when connected to orbi. Should I just direct connect to the previous router?

Yes, to mess with the ISP device, connect directly to it if you can.
