3.4.3.5 Virtual Server Configuration
Being a natural Internet firewall, the ADSL Router protects your network from being accessed by outside
users. When it needs to allow outside users to access internal servers, e.g. Web server, FTP server, E-
mail server or News server, this product can act as a virtual server. You can set up a local server with
specific port number that stands for the service, e.g. Web (80), FTP (21), Telnet (23), SMTP (25), POP3
(110), DNS (53), ECHO (7), NNTP (119). When an incoming access request to the router for specified
port is received, it will be forwarded to the corresponding internal server.
