2.2 Virtual Server

BLW-54MF can enable Virtual Server function, and remote hosts can use public IP address to connect with the Internet and FTP and then enter the LAN, but all the PCs on the LAN will not be seen from the outside. Virtual Server function can let users set a local server with specific port number which stands for the specific port, such as Web (80), FTP (21), and Telnet (23). When BLW-54MF receives an incoming access request to the specific port, it will forward the request to the corresponding internal server which means the external request for accessing a specific port will be reassigned to a different port

To enable Server Port is like to open the firewall, which exposes your LAN to users on the Internet. It is to say that the NAT function of BLW-54MF will not be able to provide protection and prevent hackers.
