Strange Problem with Port 80

That could be true.  I believe we are actually using Surf Control.

Would it be likely that this proxy would not affect Squid, yet would affect Varnish?

I ask, merely because Squid appears to be working properly.

And I'd much rather use Varnish than Squid at this point and would like to find a solution or at least an explanation so I can do some other testing from a non-proxied location.

My guess is that there is some sort of content-scanning transparent
proxy between you and the server.
