I am have the same issue as @Flince in this topic: DHCP guest reservation alert triangle
I have rebooted my router, but the warning persists. The address reservations do appear in the LAN settings.
This is on a Flint2 - Admin Panel 4.9.0
My main network (from which I’m accessing the router is 192.168.8.x
The network these devices are on is 192.168.9.x
Is there any update on this? Is there actually an issue here in setting an address reservation on a different subnet, or is it just a misleading warning? The reservation does seem to be working.
