Hmmm, I may be unclear on this. When doing DNAT, is the source IP address of the 
traffic coming from firewall and going to the internal host set to the internal 
address of the firewall? Or does it remain the address of the outside host that 
initiated the traffic in the first place.

I always *assumed* (a bad thing) that it was the latter. Thus my statement regarding 
the need for SNAT on the outbound traffic.
