Hi Sten,

Thanks for your help and the DHCP server is working fine. But just wonder if the server is serving over 100 static clients and I think it is not possible to configure the dynamic address pool with those static clients in the deny list.

Best Regards,
Billy

Hi

First pool is ok, second pool forbids BOOTP clients but still allows all
dhcp clients, including those from "Static-1".

You may want to try adding:
deny members of "Static-1"
to the second pool, that way an address will only be given from first
pool to any member of Static-1.
