I hope someone can help me with this problem, it's been driving me insane for a while now. We have a firewall which, for reasons too long, convoluted, and mired in corporate mud, still runs 6.0.1 and cannot be upgraded. We need to disable the Squid transparent proxy completely, as it is interfering with some other functionality on our network. We have filtering and web control handled using another product, so we don't need this functionality at all.
I found the link;
http://wiki.contribs.org/Firewall#Bypass_ProxyWhich, with a minor edit, allows me to bypass it for one or more specific sites, which is nice, but what we really need to do is just remove Squid from the equation completely.
A preemptive thank you to anyone who can assist with this, and save what little of my hair I have left!
