Hi All,
Thank you guys for your help
I have tried your suggestions,
Yes Ron I know that two programmes can't both listen on the same port at the
same time
but I thought the Apache was essential for the Proxy server, so thanks for
the suggestion,
I am including bits of my config here, because now I am getting "Access
Denied" even from a local network:
Can you guys please take a look at it and see if you can spot what's causing
the access denied.
note I have tried to allow everything and removed all the "deny" directives
and yet it's still denies any access from my local network.
That is why I get so confused with Squid, I don't understand it's logic to
be perfectly honest, and let me remind you that this config used to work
just fine at least it used to allow access to the internet to all the
clients on my local network.

Can anyone see what's wrong with this config and if possible to point it out
to me, your help would be much appreciated

Thanking you in advance
