DNAT probs

hi all

I've got this network as sketched below...

                  internal net
                      |
                      |
                +-----+----+
+--------+      |          |
| router +------+ Firewall |------ dmz
+--------+      |          |
                +----------+


The computers on the dmz and the internal net have all unofficial addresses 
with DNATing into the DMZ for those that should be available from the 
outside.

The problem occurs when a computer on the dmz (192.168.x.y) tries to address 
another computer there by its official address (resolved from DNS). The 
firewall (netfilter/iptables) doesn't seem to be able to do the dmz -> 
netfilter -> dmz NATing.

Any ideas?
