ADVANCED – VIRTUAL SERVER
Use this window to set up forwarding rules applied to inbound (WAN-to-LAN) traffic. The Virtual
Server function allows remote users to access services on your LAN such as FTP for file transfers or
SMTP and POP3 for e-mail. The Wireless Broadband Router will accept remote requests for these
services at your Global IP Address, using the specified TCP or UDP protocol and port number, and
then redirect these requests to the server on your LAN with the LAN IP address you specify.
Remember that the specified Private IP Address must be within the useable range of the subnet
occupied by the Router.
UDP/TCP port redirection is used to direct inbound traffic to the specified servers or workstations
on your private network. Port redirection can also be used to direct potentially hazardous packets
to a proxy server outside your firewall. For example, you can configure the Router to direct HTTP
packets to a designated HTTP server in the DMZ. You can define a set of instructions for a specific
incoming port or for a range of incoming ports. Each set of instructions or rule is indexed and can be
modified or deleted later as needed.
Below you will find a list of some common used ports and their corresponding application:
Port Application Port Application
20 FTP Data (FTP Server)
21 FTP (FTP Server)
22 SSH (Secure Shell)
23 Telnet
25 SMTP (Mail Server – Outgoing)
80 HTTP (Web Server)
110 POP3 (Mail Server – Incoming)
2000 Remotely Anywhere
5800 VNC
5900 VNC
For more ports and their corresponding applications, see: http://portforward.com/cports.htm
Note: When you are using an application which supports UPnP Port Mapping, the router can be
automatically configured by the application when needed. In that case, you don’t need to
setup your port mappings manually.
Note: When using Virtual Server rules, it is advised to configure the computer(s) with a Fixed IP
Address instead of a Dynamic IP Address.
Note: In the next picture you will see an example of a Virtual Server configuration.
