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.
