I have problem with squid

I have a network of Ip Range 10.120.1.0/24, and i providing Net Access to clients by SQUID proxy server.

Now i want a acl that restrict some of the above IPs (10.120.1.1 - 10.120.1.50) to access some web sites and full access to some IPs (10.120.1.51 - 10.120.1.100).


I already created a file of web sites that has to be restrict.

That is working well.

But question is here that when i am applying this acl list to my squid all the IPs get restrict to access web sites that is in the list.

Pl. help me to out of this problem.
