First of all I'm a total noob

Second let me explain you my problem.
I have set up a squid anonymous proxy server following this guide:
http://www.howtoforge.com/anonymous-...d-3-centos-5.x
so I'm using a ncsaauth system.
Let's say I have 2 users test and demo and let's say I have 4 outgoing ip's on the server.
I want user test to be able to use 2 of the ips and user demo to be able to access the other 2 ips.
On my current configuration each user is able to access any ip from my server. I know I should do this with acl but I have no idea how to do it.
The problem is better described here

but this guy didn't got any answer.
Also search about 2 days and I wasn't able to find anything.
Thanks in advance for the help
