Well, there was no firewall drawn in your network topology in
that visio file. Anyway, admitting that you want to enforce security
measure, but you shouldn't make your networks like that.
Just put two disjoint/mutually exclusive network (addresses) to
avoid problem. (Cf some network books.)
I've no idea what you mean by "source machine replying ..." One
thing is sure, your router is lost by your config.
