Model: Archer AX20

Hardware Version: V1

Firmware Version: Archer AX20 v1.0

Hi guys, a version of dropbear is running on my wireless router (SSH-2.0-dropbear) on TCP port 20001. All unnecessary services have been disabled but I failed to pinpoint this TCP port 20001.

On another note, on the same device, no firewall logs have been register and or will we have a flexibility to block TCP/UDP ports in the future.

Thanks

Hello @dazoveride

Thank you for reaching out to us and welcome to the TP-Link community.

As far as I'm informed, port 20001 is used for connection via SSH, and it's opened and reserved for the secured connection between the Wi-Fi router and the Tether app by default.

Please be aware that you cannot manually disable it.
