What do you want to block?

1) Users from the school accessing another proxy somewhere? Then you need
   to block all http/https requests on your router. I.e., every connection
   that does not come from your proxy needs to be blocked.
2) Other users from the outside using your proxy? Define an ACL to allow
   access only from your internal network. Or have Squid listen on the
   internal network interface only.

Hope this helps,

Peter
