使用 FTP (Windows OS)

FTP傳輸速率快，可用於在家庭網路（LAN）和遠端（WAN）。然而，文件必須先傳輸到電腦，然後才可以打開並查看。此外，您必須知道您的網路伺服器的IP地址，才能進行連線動作，遠端連線則要確認您的路由器轉連線埠(20~21)是否有開通。

您可以在管理頁面中的系統設置 > 系統資訊 > NAS資訊內，找出您的網路伺服器的IP地址。「本地 IP 位置」可用於您的家庭網路；「UPnP通訊埠轉發」的IP，可用於遠端連線。

使用FTP時，我們建議您安裝一個專用的 FTP客戶端軟體。這不僅是更方便，也可以更容易管理您的帳戶和檔案。

If you would like to login remotely using FTP, set up port forwarding on your network router first. Redirect the incoming FTP traffic on port 21 to the IP address of your network drive. Otherwise, you can only use FTP when both your computer and the network drive are connected to the same local network. For more information about port forwarding and how to setup your network router, please see the guides at http://portforward.com or refer to the documentation of your network router.

Setup FTP Service

Login to your network drive as administrator.
Go to Preferences > FTP.
Make sure the FTP service is up and running.
If you plan on using an SSL encrypted FTP connection, enable the option Enforce SSL.

File Explorer

You can use the file explorer to open an FTP folder but in general, we recommend using a 3rd party FTP client.

On your computer, open the file explorer.
In the address field, enter ftp:// followed by the IP address of your network drive and click Enter on your keyboard or click on the Go to arrow in the file explorer.
When prompted for the login credentials, enter the username and password of your user account on the network drive and click Log On. As an example, the administrator would enter admin for both username and password.
You can now manage your files on the network drive.

If you prefer, you can also add the username and password to the URL, in order to reduce the steps it takes to login and remove the additional password prompt. The correct syntax for the URL is ftp://username:password@192.168.33.30.

FTP Client

A FTP client makes it easier to manage multiple accounts and it is also more convenient to transfer the files. In addition, the FTP client provides functions like pause, resume, error logs, backup and more. If you already have a FTP client, simply use your preferred program. If you are still looking for a client, you could try FileZilla or Core FTP just to name two.

Start up your FTP client. In this example, we are using FileZilla.
Open the Site Manager.
Click New Site and create a new account for your network drive.
For the host, enter the IP address of your network drive. On your home network, use the local IP address. For remote access, use the external IP address.
For the protocol, select FTP - File Transfer Protocol.
For the encryption, select Use plain FTP. If you have setup the FTP server to use SSL encryption, select Require explicit FTP over TLS instead.
For the logon type, select Normal and then enter the username and password of your user account on the network drive. As an example, the administrator would enter admin for both username and password.
Under normal circumstances, these are all the settings you have to configure and the rest can be left at default. However, if you have changed the port number for the FTP server and it's not using the default port 21, remember to enter the correct port number in the FTP client at this point.
Double check all your settings and then click Connect. If you are using SSL encryption, you will be prompted to accept the certificate at this point.
You can now manage your files on the network drive.
