VoIP ROUTER ADSL

3.6.3.6 Virtual Server

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.

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.

Public Port (from) & Port (To): Enter the public port number & range you want to configure.

Port Type: Select TCP if you want to scope for the connection-based application service on the

remote server using the port number. Or select UDP if you want to scope for the connectionless

application service on the remote server using the port number.

Host IP Address: Enter the IP address of certain internal server to which requests from the

specified port is forwarded.
