Add Virtual Server - Billion BiPAC 7402GL R4 User Manual

Add Virtual Server

Because NAT can act as a "natural" Internet firewall, 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 specifically create Virtual Server entries to forward those ports to a PC on your
network.
When your router needs to allow an outside user to access the internal server, 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 specific port number for this service, 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 specified port is received, it will be forwarded to the corresponding internal server.
Application: User defined description to identify this entry or click the Application drop-down
menu to select an existing predefined rules.
: 20 predefined rules are available. Application, Protocol and External/Redirect
Ports will be filled 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 used. The protocol used is
determined by a particular application. Most applications will use TCP or UDP.
Time Schedule: User defined time period to enable your virtual server. You may specify a time
schedule or select "Always on" for this Virtual Server Entry. For setup and detail, refer to Time
Schedule section.
External Port: The Port number on the Remote/WAN side used when accessing the virtual
server.
Redirect Port: The Port number 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. List all existing PCs connecting to the network. You may assign a PC
with IP address and MAC from this list.
