I have a server with 10 ip's that I want to give access to some friends via authentication but I'm stuck on squid's config file.

Let's say I have these ip's available on my server:

212.77.23.10 212.77.1.10 68.44.82.112

And I want to allocate each one of them to a different user like so:

212.77.23.10 goes to user manilodisan using password 123456 212.77.1.10 goes to user manilodisan1 using password 123456 68.44.82.112 goes to user manilodisan2 using password 123456

I managed to add the passwords and authentication works ok but how do I do to restrict one user to one of the available ip's?

I have a basic setup from different bits I found over the internet but nothing seems to work. Here's my squid.conf (all comments are removed to make it lighter):

acl ip1 myip 212.77.23.10
acl ip2 myip 212.77.1.10
