Firmware Version:

I find v1.31 firmware breaks the function of NAT loopback/hairpinning on X55 US version 1.30 hardware.

 

Would anyone advise?

Hi, is the current firmware 1.3.1 Build 20251122 Rel. 36074?

Are the satellite Deco units connected via Ethernet Backhaul?

-Can I have some screenshots of the network maps on the Deco App:

By the way, what are the local servers that you plan to access locally via the public IP/domain?

Wait for your reply.

Best regards.

Thanks for your quick reply.

 

The firmware version is v1.3.1 Build 20251122 Rel. 36074

Satelite Deco connected via Ethernet Backhaul as attached in the jpeg.

Nginx Proxy Manager was installed in a server of my local network.
Public ip and domain of the all services cannot be accessed by local devices via Local Network Wi-Fi but they can all be accessed via mobile network.

Local ip of all services can all be accessed.

I think the reason is that NAT loopback/haripinning does not function anymore after the update of the firmware.

 

Any idea?

Hi, thanks for the update.

I saw a similar feedback a few days ago on another model, but I'm not sure why it was triggered after the firmware upgrade.

I'll follow up on your case via email and ask the senior engineer for further assistance.

Please check whether you can receive my email.

Best regards.
