All of my devices connected to the 2.5G port cannot be connected to the AX86U via openvpn. May I ask what is the problem?

Look to the switch connected to that port. My NAS connected to the 2.5 GHZ port can be reached over OpenVPN.

I did not use any switches on the 2.5G port. openvpn is a server program that comes with the firmware. How should I troubleshoot it?

At the time of ASUS official firmware version 384, it was normal, and I did not change anything after using the Merlin firmware.
