5.6.4 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 numbers 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.

For example, if you set the Public Port number 21 (FTP) to be mapped to the IP Address

192.168.1.100, then all the ftp requests from outside users will be forwarded to the local

server with IP address of 192.168.1.100.
