Sam,

I'm not sure what you are running into, but if you did a quick swap and 
test, your switches may not have caught up to the changes by the time 
you tested.  I ran into that when doing a midday cutover to a new 
firewall.  You can avoid that by pinging from Leaf to the DNAT target 
and vice-versa.  Once you see those pings going, this is a non-issue.

Here is a rule from a functional firewall that is DNAT'ing traffic 
arriving on a specific interface (in this case the only one in zone 
net2) and a specific (fake) IP on that interface for you to compare to 
the old version of the rule.

> DNAT         net2   loc:10.1.3.4          tcp     80       -  69.254.254.254
