Using the -O/--only-site option should prevent setup from trying to 
retrieve the mirror list.

You'll then need to explicitly specify a mirror with -s/-site or via the 
GUI (Note that this accepts Windows paths as well as URLs).

If this means all mirror sites are also blocked, then you'll either need 
to provide a local package repository, or use setup's separate download 
and install actions.

The way that is supposed to work:

Run setup in "Download without installing" mode somewhere it can access 
a mirror, with the desired packages selected.

Then run it again in "Install from local directory" mode, with the same 
"Local package directory", and set of packages selected.

In practice the 2nd step can be very slow because (for some reason lost 
in the mists of time) setup checks for the existence of every possible 
package in the local package directory.  As a hack, this check can be 
disabled with -m/--mirror-mode.
