Blocking Internet for certain ip address .

How do you block internet access for certain ip address . I have bind them

i have a 2820n

i have searched on the forum no match

Bind the machines that you DO want to have internet access, and leave the rest on DHCP

Enabled 'Strict Bind' to prevent any machines not in the bind list from accessing the internet.

Thanks for the prompt reply
