Hi Mark That was our first preference (seen from a functionality point of view), however having those ports open from all the clients to the internal side is unacceptable to the network security people since it would involve having to allow sessions being initiated from clients on the outside to the server on the inside and they will not allow outside initiated connections. The solution with the external server placed between two firewalls and other stuff where you only needed to permit traffic from on IP to one IP on specific ports was the only way to transport data from the outside to the inside that could be approved.
