The Allow filter is used to assign IP addresses to those MAC addresses only which are added in the allow list. Whereas, the Deny filter is used to restrict the assigning of IP addresses to those MAC addresses which are in the deny list i.e. DHCP Server would not assign IP Address to the clients that are part of the Deny Filter. For this practical, we will configure the Deny Filter. Right click on Deny and then click on New Filter.
