Add Virtual Server
Because NAT can act as a “natural” Internet rewall, your router protects your network from being
accessed by outside users when using NAT, as all incoming connection attempts will point to your
router unless you specically create new Virtual Server entries to forward those ports to a PC on
your network.
When your router needs to allow outside users to access internal servers, e.g. a web server, FTP
server, Email server or game server, the router can act as a “virtual server”. You can set up a local
server with a specic port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21),
Telnet (port 23), SMTP (port 25), or POP3 (port 110), When an incoming access request to the router
for a specied port is received, it will be forwarded to the corresponding internal server.
Time Schedule: A self-dened time period to enable your virtual server. You may specify a time
schedule or Always on for the usage of this Virtual Server Entry. For setup and detail, refer to Time
Schedule section
Application: Users-dene description to identify this entry or click Helper to select existing predened
rules. There are 20 predened rules. Click the Radio button to select the rule; Application, Protocol
and External/Redirect Ports will be lled after the selection.
Protocol: It is the supported protocol for the virtual server. In addition to specifying the port number
to be used, you will also need to specify the protocol being used. The protocol used is determined
by a particular application. Most applications will use TCP or UDP.
External Port: The Port number which will be used by the Remote/WAN client when accessing the
virtual server.
Redirect Port: The Port number which is used by the Local server in the LAN network.
Internal IP Address: The private IP in the LAN network, which will be providing the virtual server
application. Candidates list all the existing PCs connecting to the network. You can assign a PC a
specic IP address and MAC from this list.
Example:
If you like to access your Router remotely through the Web/HTTP at all time, you would need
to enable port number 80 (Web/HTTP) and map to the Router IP Address. Then all incoming
HTTP requests from you (Remote side) will be forwarded to the Router with the IP address of
192.168.1.254. Since port number 80 has already been predened, next to the Application click
Helper. When a predened rule window pops up, select HTTP_Sever from the rule list.
Application: HTT_Sever
Time Schedule: Always On
Protocol: tcp
External Port: 80-80
Redirect Port: 80-80
