For Example
: You want to share some large files with your friends outside of your local
area network, however, they are too big, and it’s not convenient to transfer them. Then, you
can build a FTP server on your computer and set the router’s port range forwarding to
enable your friends to access to these files on your computer. Suppose that your FTP
server or your computer’s static IP address is 192.168.0.10, and you wish your friends can
access the server through the default port 21 and adopts TCP protocol.
Please follow the steps below to configure.
1.Enter 21 in both start port and end port fields, or you can also select FTP from the
well-known service port and its port 21 will be added to the corresponding field
automatically.
2. Enter 192.168.0.10 in the LAN IP column, and then select “Both” as the protocol and
select “Enable”.
3. As the picture shown below.
4. Click the “Ok” button to save the settings.
And now, when your friends want to visit the FTP server, they only need to enter
ftp://xxx.xxx.xxx.xxx:21 in the address field. Here, xxx.xxx.xxx.xxx means the router’s WAN
IP address. For example, when your router’s WAN IP address is 172.16.102.89; your
friends need to enter ftp://172.16.102.89:21 in the address field.
