I used the gui to change what the MT gives out for IP addresses to a couple devices. I also verified they are correct under Network / DHCP Reservations.
I have rebooted both devices a few times over a couple days, they are still using the original DHCP address. Yes the lease is 24 hours so that has passed too. I am running 8.1.1. I have used reservations on many different devices providing dhcp in the past and present and they always worked. Does the MT need something different? I verified the MAC addresses for the interface getting the address. What am I missing? -Bill
