DSTNAT & Rb1100AH

I seem to have an issue with dstnat rule on my RB1100AH. I have a live ip assigned to the unit, and I forward traffic coming to it to a remote CPE on my wireless network. This has worked fine since I set it up a while ago, but today stopped forwarding and havent been able to resolve. The hardware is an RB1100AH ver 5.5 - has anyone experienced / been able to reolve this?

Post the output of “/ip address print detail”, “/ip route print detail”, “/interface print”, “/ip firewall export”, and an accurate network diagram.
