Reflection and Hairpin NAT?

[pheriko]

Hello.

For the Reflection and Hairpin NAT setup, the dns that handle the domain name is external, do we need to setup a PTR ?

I have a web server behind opnsense LAN, I setup NAT reflection base on the doc from opnsense, but don't seen to work, if I setup a dyndns for the  hostname, works but if I Use the current domain name hosted on a X provider doesn't work, what I see is that the PTR doesn't work.

This is why my question, any input will be appreciated, regards.
