Orbi RBR50 doesnt pick up when external IP address changes

    All

     

    All - FYI - i finally found out what the issue was

     

    Aussie Broadband has a system in place that doesnt match up the true external IP address with the one used as "external" in the router - which is why they dont match.

     

    This was not the case when i was with Optus, they matched by default.

     

    Aussie Broadband explained that they have a default system for IP addresses that has that effect, so i asked them to switch that system off for me - and it fixed it - the two IP's are the same now

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

 

Possible the modem wasn't correctly passing thru or the modem didn't reboot or update it's WAN IP table.

      Has a factory reset and setup from scratch been performed since last update?
