WebDAV Access from LAN Blocked on AX3000 (Port 6008) — Cyberduck 401 Unauthorized

I'm using a GL.iNet AX3000 router (firmware current as of Oct 2025) and attempting to access a connected USB drive via WebDAV from a Windows 11 25H2 ARM-based PC. The router is intended to be a front end for the drive.

I already found in Windows 10 that to get access I have to connect to the AX3000 router as my wi-fi network. However, I then can’t connect to my Wi-Fi connected printer, etc. Those devices are connected and have to stay Wi-Fi connected to my ISP’s router. That’s not ideal, but workable in Windows 10. Windows 11 is another story. So please don’t tell me I failed to connect to the router’s wi-fi.

Other settings are:

  • WebDAV is enabled in the admin panel

  • Port is set to 6008

  • Shared folder path is /disk1_part1, disk name: OLCMC 2024

  • “Allow Access WebDAV from WAN” is toggled on

  • No option exists to allow WebDAV access from LAN

From my LAN-connected PC, Cyberduck 9.2.4 (dated 15 Sep 2025) consistently returns:

  • 401 Unauthorized when using correct router credentials

  • 405 Not Allowed when trying anonymous login or alternate paths

I’ve confirmed:

  • WebDAV service is reachable at 192.168.8.1:6008

  • Credentials match router login

  • Path /disk1_part1 is valid and mounted

There appears to be no way to enable WebDAV access from LAN clients. The only toggle is WAN-specific, and LAN requests are rejected even with valid credentials.

Can you confirm whether LAN access via WebDAV is supported on AX3000? If not, is there a firmware workaround or alternate method to expose /disk1_part1 to LAN clients via WebDAV or FTP?

I’ve already tested SMB1, FTP, and fallback tools like WinSCP and Cyberduck.

Thanks in advance.

Hi

We have tested the MT3000 with firmware 4.8.1 and are able to use the Cyberduck connect the WebDAV server on LAN or WAN without problem.

Note: If you are using the HTTPS protocol, please trust the GL self-signed certificate in Cyberduck.

Here are our test settings:
