Clients Keep Disappearing from Address Reservation List

User123 · 2024-10-23T18:50:03.980Z

Hi everyone. I'm encountering a strange issue with the Address Reservation feature on my Flint 2 router. I've added eight clients to the reservation list, but the last three consistently disappear from the list periodically. I can re-add them, but after some time, they vanish again. This issue only affects these three clients; no others are affected. Does anyone know what might be causing this or how to fix it?

Could it be that your devices are using random Mac when they re-connect? If set to random Mac then obviously your reserved address will not apply as the devices Mac has changed. For example on android you can select use "device Mac" when you join the network you devices Mac will stay the same and as a result the address reservation will work. By default android can suggest using randomised Mac for security reasons, again you just toggle to use devices Mac before joining the network (could be under advanced settings)

No, I specifically disabled random MAC addresses for those clients before adding them. Even if I hadn't, why would the settings disappear on their own? They wouldn't work with randomized MAC addresses, but why disappear? It seems more like a firmware bug to me.

It could well be. I would suggest giving more info about the 3 clients in question and wait for a staff member to comment.

These devices are all Android-based, including one phone and two TV sticks. The only other commonality among them is that their IP addresses are utilized in mwan3 rules to direct traffic to a specific WAN port, rather than load balancing like the other devices.

Using this thread instead of creating a new one with the same issue.
I also have this problem.
I have a Slate AX on 4.6.8 firmware.
All the clients on the "Address Reservation" list disappear randomly after creating it.
I thought it was after a reboot since I had it scheduled, but it turns out that is not the case.
Unfortunately, I need this list to be permanent as it was before, otherwise some things break on my network.
Any assistance would be appreciated.
