Re: [squid-users] ACL and localhost problems

In this test I do not want to allow for the local network. I am using a web
content filter (Dansguardian) to listen on port 8080 and then direct to 3128
of squid. I do not want users to be able to connect directly to squid. The
web content filter is on the same system and it was my thought that it would
use localhost. The howto's on Dansguardian speak of this and even some of
the archives from this list seem to point that way. As I said in the
example below, although I may not have worded it correctly, if I change the
line reading "http_access allow localhost" to "http_access allow all"
everyone can get to and use the proxy. This is allowed by "acl all src
0.0.0.0/0.0.0.0 unless I am mistaken.

I hope that this makes more sense.
