Intranet IP address in internet setup
Having previously been up and running just fine, I've changed ISP and am now unable to get port forwarding to work.
I think the issue is in the Orbi, not the ISP but I can't figure out what the problem is.
One thing I have seen is in the Internet Setup screen, there is an Intranet IP address option which is currently disabled. I can't tell what it was set to before and the help center doesn't include any information about it...

(I enabled it just to reveal the other options, otherwise they are hidden)
I downloaded the instructions again from the netgear support site but they make no mention of this setting.
What is it for, and what is the effect of having it not enabled?
I presume you mean that IPv6 is disabled on the RBR router?
Ya seen some ISPs have odd issues with IPv6. Not to mention Orbi FW can have some oddities as well.
Glad you got it working. Please mark your thread as solved so others will know. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

What region and language is this router using? (Pull down in upper right corner of the screen for language)
I suspect typos. My Internet screen looks like this:
Notice the spelling is "internet" (not "intranet") and has "from ISP". No "Enable". And the static IP options are visible all the time (just greyed out).
What firmware version is on this router? Current is v7.2.6.21.
Port Forwarding works only when the router has a public IP address,i.e. is not "behind" another router. What equipment did the new ISP provide? is it a plain modem or fiber ONT, or is it a combination device?
I have that setting too. The mystery one is near the bottom of the screen for me.
It looks like I have the current software - v7.2.6.21_5.0.20
Router is connected directly to the ONT via the WAN port. It's exactly the same physical connection that I had with my previous ISP until a few weeks ago.
in this case, I moved from Sky to PlusNet ... this lost me IPv6 (which I hadn't appreciated) and needed me to use the PPPoE configuration which I had never done before. I do have a public IP address so double NAT is not an issue.Here's my full screen with public IP redacted.
I since tried enabling the mystery setting but, of course it doesn't seem to have made any difference.
I'm sure port forwarding was working before as I have servers that connect in to a machine on my LAN to read a status page and they worked fine until yesterday. I did try (and fail) to get tunnelbroker services working which led to this headache; I've since completely disabled the IPv6 function in the router but port I'm still having issues reaching the machines via the forwarded ports from the internet and from the lan (via my public IP). On the LAN the target ports are reachable and responding fine.
I'd make contact with your ISP and have them help you with this. Be sure to ask them if connecting a external router ot there ONT is supported by them or if there router is needed.
Power OFF the ONT and RBR for 1 minute then back on as well.
