RBR50 crashes during configuration

Hello,   since I've updated to 2.5.1.8, the system has become a real pain in the ass when configuring dhcp and I have no clue how to fix it. I need to reserve the addresses of about 50 IoT devices ...

    Hi, i spent several hours re-installing and configuring the devices. Fact is, I can't restart the system since it tends to forget the configured addresses. The workaround is to use backups every time and since the router is hooked to my UPS, chances are that it's not gonna restart due to power loss. Fingers crossed and in the meantime I've looked at other solutions...

     

    To finish this story: today, my router had a fatal accident with a 10 pound hammer, crashed it completely to pieces. It was quite satisfying... The remains will be delivered to the local dump.

     

    The reason for this is that this little **bleep** chose to give my surveillance cam a new network address the other day (yes, not the one that's still reserved in the DHCP-Server) - what's more, it chose one that collides with my internal dns server address - which is connected via cable -, causing just a very little bit of a bloody mess in my network. I've checked it twice: the cam gets a new address every time(!!) it reconnects. Seems like *this* Orbi didn't even know the term "lease time". In combination with the colliding addresses, this is just a no-go. I'm done with it and switching to a more reliable system. Lucky enough, the test systems are already sitting on my table.

     

    Just a last word about the double NAT and my network setup: the internal net behind the Orbi-DHCP caused the problems. It's never shown any problem with the internet connection or the devices in my DMZ zones. I really tried to fix these problems via updates, reserving addresses  etc but if the systems doesn't even remember that the same MAC has been given an address just 10 seconds before (and leases a new one every time), it's junk. Even more, if it ignores fixed addresses.

     

    Cheers,
