Well‐known Service Port: The well‐known Service Port lists widely used protocol ports. Simply select a
port, an entry ID, and click the "Add to" button to transfer the selected port to the corresponding fields
of the selected entry. In case you cannot find the port you will need to enter it manually.
Example: You want to share some large files with your friends who are not in your LAN, however, it is not
convenient to transfer such large files across the network. You can set up your own PC as a FTP server and
use the Virtual Server feature to let your friends access these files. Assuming that the static IP address of
the FTP server (Namely, your PC) is 192.168.0.110, you will want your friends to access this FTP server on
the default port of 21 using the TCP protocol, details are explained below:
1. Enter 21 in both Ext Port and Int Port fields or select FTP from Well‐known Service Port and an entry ID
21 will be automatically transferred to the corresponding fields of the selected entry.
2. Enter 192.168.0.110 for the IP Address, select TCP and then select Enable.
