IF everything your users need to be able to reach the Internet with CAN be proxied, and management will pony up the cash for a proxy server and software, then yes, the proxy server should go in the DMZ. Not every organization can justify both the restriction and the expense.
True.
A proxy means that there is no direct traffic ONLY if there are rules on the firewalls that prohibit direct traffic. (A "deny all" rule is still a rule.) So for organizations that deploy a proxy this way, the second ruleset is extremely simple -- but not void.
Ah, my bad again. I meant "deny all" when I said I would consider the ruleset void. Of course "deny all" is a rule too, but as it is (or should be) the default rule I didn't look at it as a ruleset. Sorry for the mistakable wording.
