Virtual Server
Advanced > 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 32) 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. To open several ports please refer
to “
Gaming” section on page 35.
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 24).
2. Click on Advanced, and click on Virtual Server.
3. Review the virtual server settings.
• Rule Enabled: Selecting Enabled turns on the virtual server and selecting
Disabled turns off the virtual server.
• Rule Name: Enter a name for the virtual server.
• IP Address: Enter the IP address of the device to forward the port (e.g.
192.168.10.101).
• 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. 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.
• Public Port: Enter the port number used to access the device from the Internet.
• 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.
• Schedule: Select the defined schedule you would like to have the rule to be
applied (see “
Set Schedule” section on page 31).
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.
• Add: Saves a new virtual server entry.
• Clear: Discard changes to an existing virtual server.
