Reach static NAT mappings from inside

Greetings

I've been playing around with FDM and an FTD 7.0.1 and I'm having trouble understanding how to reach a NATed host from the inside network. It's a pretty basic setup with 192.168.1.0/24 as my inside network and 10.10.10.0/24 as an DMZ with some hosts with public services.

I've set up a NAT with port translation from DMZ to Outside where the DMZ host port 443 is translated to Outside 8443. FDM won't let med select the advanced DNS option but the NAT rule and corresponding ACL is working for traffic coming in from the Internet but I don't understand how to get this to work from the inside 192.168.1.0/24 network using the same DNS entry as on the Internet which resolves to my Outside IP.

 

Any suggestions?

Regards

Fredrik
