So if you want to use the shares as local folders from windows explorer, the best way is to use the webdav feature.
- first, you
should enable the https server (and so use the port 443)
- enable what shares you want to get access via WebDav ( in WebDav menu). Please note that the users access are then the same than those set for the samba server.
That's all on the NAS side.
On your router (ISP box), you must open the port 443 (add a rule TCP in/out toward the local IP of your NAS).
If you don't have a static public IP (WAN IP), you must use a DDNS provider instead of your public IP.
On your remote PC, create a network drive (
http://help.wildapricot.com/display/DOC/Setting+Up+WebDAV+in+Windows+7) with this url
https://yourddns/sharename (or
https://yourWANIP/sharename if you have a static IP)
Note: according with your windows OS, it could have an issue with the CA certificate of the NAS. In this case, you must manually import it as a trust root authority.
