Virtual Server
Access > Virtual Server
Virtual Server (also called port forwarding) allows you to define specific ports (used or
required by a specific application) and forward them to a single IP address (a computer
or device) on your network. Using this feature is more secure compared to using DMZ
(see DMZ on page 34) in which DMZ forwards all ports instead of only specific ports
used by an application. An example would be forwarding a port to an IP camera
(TRENDnet IP cameras default to HTTP TCP port 80 for remote access web requests) on
your network to be able to view it over the Internet.
Since most ISPs constantly change your home IP address, to be able to access the Virtual
Server port(s) from the Internet it is recommended to setup Dynamic DNS service (See
DynDNS section).
1. Log into your router management page (see “Access your router management page”
on page 27).
2. Click on Access, and click on Virtual Server.
3. Review the virtual server settings.
• Enabled – Selecting Enabled turns on the virtual server and selecting Disabled
turns off the virtual server.
• Name – Enter a name for the virtual server.
• Protocol – Select the protocol required for your device. TCP, UDP, or you can
select Both to choose both TCP & UDP (recommended).
Note: Please refer to the device documentation to determine which ports and
protocols are required.
• Private Port – Enter the port number required by your device. Refer to the
connecting device’s documentation for reference to the network port(s)
required.
• Public Port – Enter the port number used to access the device from the
Internet.
Note: The Public Port can be assigned a different port number than the Private Port
(also known as port redirection), however it is recommended to use the same port
number for both settings. Please refer to the device documentation to determine
which ports and protocols are required.
To simplify configuration, there is a list of commonly used pre-defined virtual server
entries to modify, otherwise, you can choose to manually add a new virtual server.
• LAN Server – Enter the IP address of the device to forward the port (e.g.
192.168.10.101).
Note: You should assign a static IP address to the device or use DHCP reservation to
ensure the IP address of the device does not change.
