Hey Community,

 

We have received user feedback that when using official Firmware 1.2.10, or pre-release firmware 1.3.0 on Deco BE63 V2, Deco BE65 V2, and Deco BE11000 V2, NAT Loopback anomalies, such as the following, may occur:

 

  • Inability to access a local server using the WAN IP + Port from within the LAN, although it works fine via the LAN IP.
     
  • Accessing the server via the WAN IP from an external network works fine.

 

Applies to: 

Deco BE63 V2

Deco BE65 V2

Deco BE11000 V2

 

Available Solutions: 

Our R&D department has provided beta firmware to address this behavior. We encourage affected users to download and manually update to this beta firmware and to share feedback on their experience.

Hi @Ryan

 

Is this firmware file the same as the one shared in the 1.3.0 beta thread below?


https://community.tp-link.com/en/home/forum/topic/856030

 

The filenames are identical and both have the same updated date stamp of 13 February 2026.

Hi  @WelshPaul 

 

Yes, they are the same―the original pre-release thread had its download link updated to ensure users have the most up-to-date solution. 

 

This new thread was created to help raise awareness for the updated beta solution for users affected by the reported NAT Loopback behavior.
