...that usage of port 3128 was an example. Looking back, I see you're
using port 8080. It would really help if you'd actually said that
instead of burying it in some output!

Try it again, but with 8080 instead.

Erm... I'm not sure that will do what you need it to. I'm not sure, in
fact, what that does!

If you try the NOQUEUE target again with *your configuration*, not my
example, then see what it does.
