What about it? - You set common external-DNS on the customer facing side to
refer that address to the tunnel manager and the TM then takes care of the
packet's rewriting. Or did I miss something here?

As to public publishing, create a virtual server on a set of the ISP's well
known addresses and stack the servers up. What's the problem?
