New C3700 cannot make address reservations
Title says it all. I cannot make dhcp reservations for my lan devices. Get this stupid message that the table is full even though it is empty.

I've got the C3000 Firmware V1.01.05. I was having the same issue with it.
I was able to get it to take reservations by doing the following steps.
1) In the Advanced/Setup/LAN Setup screen, set the Starting IP Address to .10 (default) and Ending IP Address to .20
2) Apply Config
3) Click to add reservation. It will then pop up IP addresses that have been assigned. Go back and change the Ending IP Address to .254 (or whatever you want to use as your end IP address).
4) Apply Config
It will then allow you to add. Note that reservations IP addresses must be part of the pool. So if you want to reserve x.y.z.200 then the IP pool range must include .200. Typically when you setup DHCP reserved addresses they are not part of the pool but this device works differently.
Hope this works for you,
Steve

Thank you for your tip, srandlet!
It worked for my C3700-100NAS.
Cheers!
