TRENDnet User's Guide Open a device on your network to the Internet This router can provide access to devices on your local area network to the Internet using the Virtual Server, Special Application, method (DMZ NOT recommended). DMZ Access > Firewall & DMZ You may want to expose a specific computer or device on your network to the Internet to allow anyone to access it. Your router includes the DMZ (Demilitarized Zone) feature that makes all the ports and services available on the WAN/Internet side of the router and forwards them to a single IP address (computer or network device) on your network. The DMZ feature is an easy way of allowing access from the Internet however, it is a very insecure technology and will open local area network to greater threats from Internet attacks. It is strongly recommended to use Virtual Server (also called port forwarding, see "Virtual Server" on page 36) to allow access to your computers or network devices from the Internet. 1. Make the computer or network device (for which you are establishing a DMZ link) has a static IP address. Signing up for a Dynamic DNS service (outlined in Identify Your Network section page 33) will provide identification of the router's network from the Internet. 2. Log into your router management page (see "Access your router management page" on page 25). 3. Click on Access, and click on Firewall & DMZ. 4. Select Enable in the DMZ Host section. TEW-751DR 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 36) 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 37. 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 33). 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. 5. Enter the IP address you assigned to the computer or network device to expose to the Internet. Note: You can also click the Computer Name drop-down list to select a computer from your DHCP client list and click
