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. To open several ports please refer

to “

Port Forwarding” section on page 36.

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

(outlined in Identify Your Network

section page 32).

1. Log into your router management page (see “Access your router management page

”

on page 25).

2. Click on Access, and click on Virtual Server.

3. Review the virtual server settings. Click Save Settings to save settings.

Check the option to the left most of the entry to enable and uncheck to disable.

• Name: Enter a name for the virtual server.

Note: You can also click the Application Name drop-down list to select from a

predefined list of applications and click << to copy the information into the fields.

• IP Address: Enter the IP address of the device to forward the port (e.g.

192.168.10.101).

Note: You can also click the Computer Name drop-down list to select a computer

from the DHCP client list and click << to copy the information into the field.

• 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.

• Protocol: Select the protocol required for your device. TCP, UDP, Both (TCP and

UDP), or Other to define a non-listed protocol.

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.It is recommended to assign a

static IP address to the device or use DHCP reservation to ensure the IP address of

the device does not change.

• Schedule: Select the defined schedule you would like to have the rule to be

applied (see “Create Schedule

” section on page 34).

• Inbound Filter: Select the defined IP address range to allow access. (see “Inbound

Filter” section on page 37).

Example: To forward TCP port 80 to your IP camera

1. Setup DynDNS service (see Identify Your Network

section page 32).
