Yep, sure did. I did finally get this sorted. I was blaming the router... After clearing my browser cache, I was able to go back into the UI and add more than 3 reservations. I think this was some...

@XC90 Strangely enough - my unit is NOT accepting any reservations beyond the first three. Has anyone configured FOUR or more DHCP reservations??

@Fae Bought this, updated it. And this thing is an unusable mess. So many issues in this device. The product description says multi-net NAT routing, but that tab doesn't even exist on this device....
