Can I connent to Synology Drive in WAN

I can connect to my NAS in LAN.
But I can’t connect to my NAS in WAN. How to set to connect in WAN?

Hi~ @atoon ,

To use it over WAN, you need to configure ddns and port forwarding. It is recommended to perform port forwarding directly on the router rather than on the NAS server.
Please contact your network administrator.
