Hi Amos,

Thanks for the reply. Sorry, what I meant by that was that I was logged into the Squid Windows server using remote desktop so that I could edit the configuration so that is separate from the machine trying to use Squid a a proxy.

So it would seem like the issue is with the firewall from what you're saying? Using the most basic Squid config pointing it at the firewall as a parent should be all I need to do for the Windows username to be passed through to the firewall?
