Deco M4 second Ethernet port stop working when Internet is down

Model: Deco M4

Hardware Version: V2

Firmware Version: 1.5.5 Build 20220823 Rel. 41353

Hi,

I just setup my Deco network like the picture bellow.

The problem I am facing is that my Local Media Server, which is just an ARM64 computer running Debian, gets disconnected when the internet is down. I hypothesize that the Main Deco goes to Wan/backhaul listening mode when the eth1 gets disconnected from the internet.

I already switched the eth1 and eth2 ports, and I still have the same problem. Is there a way to force one of the ports to behave as a regular Ethernet port?

Adding more info to the first post. The problem happens when I restart the Main router, during the time that eth1 is disconnected the main Deco break eth2.

Steps to reproduce:

Set up the Main Deco
Connect it to the internet using eth 1 or 2
Connect a computer to the other Ethernet port
Start transferring a file from the Local Media Server to another computer on the WiFi network
Disconnect the Internet (Wan) Ethernet cable or restart the Modem

What happens: When I do that the Local Media Server gets disconnected until the Wan connection is restored. WiFi devices are not impacted.

What I expect to happen: Local Media Server would keep transferring the file to the other computer on the local network.
