Loopback/Hairpinning stopped working?

Model: Deco X60  
Hardware Version:
Firmware Version: 1.2.4

I had my DNS pointing to google on my DHCP server and it was resolving hostnames to my WAN IP and working fine. Now, attempting to connect on the WAN IP doesn't work. If I set my hosts file to resolve to the internal IP it works fine.

Hi, Do you plan to access a local server via WAN IP+ internet port?

PS: The tested server can not be the web interface of Deco X60 since its remote access could only be via Deco APP.

 

Could you please refer to this link and check whether you might have a double NAT issue:

Double NAT

Wait for your reply and best regards.

yeah not double NAT. Accessing internal servers on the WAN IP through a port forward.

 

it was working.

Hi, Thanks for your feedback.

Could you please explain more about "ive setup split DNS now instead"? Can I have some screenshots of the split DNS settings?

What were your original DNS settings?

 

Apart from the NAT loopback, are you able to access the internal server from an external network?

Best regards.
