Synology

Mount a Synology NAS as a Windows drive over WebDAV.

Before you begin

Prepare the following in advance:

  • Install and enable the WebDAV Server package in DSM — Synology's guide.
  • For access from outside your network, set up DDNS: DSM → Control Panel → External Access → DDNS → Add — about Synology DDNS.
  • Default WebDAV ports: 5005 (http) / 5006 (https).

Connect

  1. Click Add in the toolbar.
  2. Choose NAS → Synology.
  3. Select https, enter the server address (DDNS hostname or IP) and port, then your DSM username and password.
  4. Pick the TLS/SSL version matching your DSM setting, and click Connect.

Settings

Setting Description Default
Protocol https or http https
Address / Port NAS host and WebDAV port 5006 (https)
Path Shared folder mounted as the drive root all shares
TLS/SSL TLS version used for https auto
Timeout Seconds to wait for a server response —
Read-only Blocks writes to the mounted drive off

Behavior & limits

  • DSM's TLS/SSL profile level decides which TLS versions the NAS accepts (Control Panel → Security → Advanced): Modern = TLS 1.3 only, Intermediate = 1.2/1.3, Old backward = 1.0–1.3. Match RaiDrive's TLS/SSL setting to it — see Synology: TLS/SSL profile level.
  • DSM shared-folder permissions are enforced on the drive.

Troubleshooting

Symptom Cause Fix
Connection refused WebDAV Server package not running Start/install the package in DSM
TLS handshake fails DSM profile set to Modern, old TLS selected Select TLS 1.3, or lower the DSM profile level
Works on LAN only Ports 5005/5006 not forwarded Forward the port on your router; use the DDNS hostname
Trying to connect via QuickConnect fails Synology QuickConnect does not support WebDAV/SFTP/FTP Use a DDNS hostname (or IP) and the WebDAV port instead — see forum thread
