DNS from which machine/s? The clients, or the proxy/ies? (In a proxy
setup the clients will use DNS because they always do, and the proxy will use
DNS because it needs to contact the real server).

It's not clear to me from the above diagram which computer is running
netfilter (iptables). Tell us this and we can suggest how to redirect your
DNS requests (if indeed that is the problem).

Indeed - I would actually recommend that you chain the proxies together using
the squid configuration file, so that they know how they're interconnected.

That would not be a bad idea at all. If you're running a caching proxy, it
can benefit quite a bit from having a (very) local DNS server as well.
