Can you clarify what the issue is ?
It is as simple as needing to connect to the server at different IPs (i.e. the internal IP from inside, the external IP from outside), but using the same URL ? If so, then split horizon DNS is your friend - and I'm assuming that's what you are referring to when you say using BINDs response policy.

I run split horizon DNS at home. I have an internal zone for thehobsons.co.uk which has internal addresses for my devices, and an external zone for it which lists only the public IPs. Two views (in BIND terminology), with rules applied to determine which view is used for which clients.
Some will tell you that it's wrong - but as long as we have NAT then it's a decent and reliable workaround for the breakage that NAT causes.
