Squid + Modificações

Galera o seguinte, segue minha regra que está sem autenticação, mas com blok de downlodas e sites, mas o seguinte: Queria por exemplo:

- 2 IP's liberaram somente alguns sites
- outros 2 liberarm somente alguns sites
- e o resto tudo ate downloads

Seriam tipo 3 regras prendidas a IP's que depois eu ira prender ao MAC,

como poderia adicionar nesta regra?
