Why can I not release IP addresses? Even with a reboot it still holds on to old addresses. I created a reservation and when I look in the clients list I see 3 different addresses for the same device.

If you set your client devices to use DHCP and reboot them, they will obtain one IP address only. If you reboot Orbi, the list of attached devices will be cleared.

What modem/router(s) do you have, how are they connected, in what order are they connected, is Orbi in AP mode or router mode, what type of client device is exhibiting the problem, is there more than one client device with the problem...

Good news and bad news. 192.168.1.162 is actually a real device. It is a Wemo wall light switch. All of my other Wemo switches show up as "Belkin International" as the device model and "Wemo" as the device name. I had named 192.168.1.162 as "Chamberlian" and "Garage door" and then when I moved the device to a reserved IP, .162 was available and in a reboot it was assigned to the Wemo light switch. Which is a real problem. Apparently names stay with the IP, not the device (or, more specifically) the MAC address.) I had come from an Amplifi system and those names were tied to MACs, not IPs. I am not sure that this is what the typical user would expect when they name a device.

You need to reboot your devices (not Orbi) to get the devices to release their IPs. Also, make sure your devices are set to use DHCP to get an IP and don’t have hard coded IP addresses.

Devices have been repeatedly rebooted, IPs remain.

I am running on fiber, no modem, just a Calyx ONT that is feeding me straight Ethernet into the house. I took the orbi off line on Saturday afternoon to hook my AMPLIFI back up and check their latest firmware. I will put the Orbi back on line this evening and check it. If the system has been off for more than 24 hours, every lease should have expired.

What FW version is loaded on the Orbi router?

  2.1.3.4
  
  just plugged it back in and powered it up after 24+ hours off line.
  
  The reaerved IP at 192.168.1.99 that I set for the garage door is there, but so is the old 192.168.1.162 that was dynamically assigned days ago.
  
  i did name the device when it was .162. Can’t find a way to release this.

    It's still hard to help you without more specific information on what is going on.
    
    What exactly do you mean 1.99 is there but so is the old 1.162? The IP is where? Where are you seeing two IPs listed? On the Orbi attached devices screen?
    
    I believe all that Orbi is doing is reporting devices that respond to arp.
    
    Is this garage door device the only device exhibitng this behavior? Can you actually connect to the device at bith IP addresses? I would look at your device as the possible culprit.
    
    Anyway... if this is not causing you any actual network problems you should be able to ignore it. There is no rule against one device having two IPs. You just cannot have one IP being used by two devices.

  I recommend you make a new post about your question regarding VPN. This thread is dealing with DHCP and reservations.
