If it helps, I do not think the Squid IP is necessary at this point. The
error message happening shows the Browser is successfully contacting the
proxy. It just not permitted through.

 if you really don't want to reveal any of your IPs at all you can
replace them in the published details with a placeholder value. So long
as you pick a unique placeholder for each IP and use them consistently
through the discussion. So we can a) see clearly when two different IPs
are occuring (eg to point out when they should be the same etc.).

If you still don't want to say. Then all we can do is point you at the
FAQ about how to write access controls. Maybe it will teach you how to
write the necessary rules yourself.


 see particularly the sections above "How do I allow my clients to use
the cache?".

That FAQ says (what I think is) the solution to your problem, but the
sections above the answer are needed to understand what values need
entering into *your* particular squid.conf which may differ from the FAQ

As Anthony said the 172.* IPs are already allowed in the default config
so a simple cut-n-paste of the FAQ example text into your squid.conf at
change anything.
