Problem adding a device to port management. It's re-adding the old device

[bodger]

Hi all,

I had a Raspberry PI running pi-hole and Home Assistant, with port forwarding for the Home Assistant to allow me remote access to my dashboard. The RPi was running out of memory, so I swapped it out for an Rpi4 with 8GB. The device slotted straight into place and has the same IP address (###.###.##.###)

The old device is no longer on the network.

Within port management on the Google Home app via my Android phone, the port management still shows the old device (MAC address beginning with b8:27) and says it's "Not available". If I delete it, then it disappears from the list. 

I then add a new Port management rule, and select the new device (MAC address beginning d8:3a) put in my port rules select the prototcol and click save. I get the pop up "Rule was added successfully".

I then go back to the port management list and the old device is listed again and is still "Not available"

I can't add the new device alongside the old one because the port rule is the same for both of them.

I've tried deleting the device, exiting the app, then going back in to add, makes no difference. Every time I add the new device the old one reappears!

Any help appreciated.

Hey @bodger .

I suspect that the reason is due to IP address assigning within the Google Home app. The following article will guide you to the setting if you are not familiar: DHCP IP reservation or Set a Static IP address for a device 

• Check to make sure that the IP you assigned the new Raspberry PI wasn't statically assigned to the old one. If so, delete the old assignment and assign the IP to the new device.
• If the above doesn't work, check that MAC randomization is turned off on any capable devices which will also affect port forwarding rules.

Let me know if this solves the issue or if you need further assistance.
