Point taken, and I should have mentioned that it's NAT in play.
I agree, it's a problem that not all firewalls can hairpin public IPs back
to their private IPs, but when working with what you got sometimes the
solution isn't ideal.

Second, s/configuration/DNS/, which I would argue is the wrong layer.
Solve routing problems at the routing layer. But I realize that there
are differing opinions on this.
Nothin' ever doesn't change, but nothin' changes much.
