The D-Linkcan be configured as a virtual server so that remote users accessing Web or FTP services via the public IP address can be automatically redirected to local servers in the LAN (Local Area Network).
The D-Link firewall feature filters out unrecognized packets to protect your LAN network so all computers networked with the are invisible to the outside world. If you wish, you can make some of the LAN computers accessible from the Internet by enabling Virtual Server. Depending on the requested service, the D-Link DIR-601 redirects the external service request to the appropriate server within the LAN network.
The D-Link DIR-601 is also capable of port-redirection meaning incoming traffic to a particular port may be redirected to a different port on the server computer.
Each virtual service that is created will be listed at the bottom of the screen in thes List. There are pre-defined virtual services already in the table. You may use them by enabling them and assigning the server IP to use that particular virtual service.
This will allow you to open a single port. If you would like to open a range of ports, refer to the next page.

Private Port/Public Port: Enter the port that you want to open next to Private Port and Public Port. The private and public ports are usually the same. The public port is the port seen from the Internet side, and the private port is the port being used by the application on the computer within your local network. Protocol Type: Select TCP, UDP, or Both from the drop-down menu. Protocol Type:Select TCP, UDP, or Both from the drop-down menu.

The DDNS feature allows you to host a server (Web, FTP, Game Server, etc…) using a domain name that you have purchased (www.whateveryournameis.com) with your dynamically assigned IP address. Most broadband Internet Service Providers assign dynamic (changing) IP addresses. Using a DDNS service provider, your friends can enter in your domain name to connect to your server no matter what your IP address is.
