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.
Enter a name for the rule or select an application from the drop-down menu. Select an application and click << to populate the fields.
Enter the IP address of the computer on your local network that you want to allow the incoming service to. If your computer is receiving an IP address automatically from the router (DHCP), you computer will be listed in the “Computer Name” drop-down menu. Select your computer and click <<. 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. Inbound Filter: Select Allow All (most common) or a created Inbound filter. You may create your own inbound filters in the Advanced > Inbound Filter page.
The schedule of time when the Virtual Server Rule will be enabled. The schedule may be set to Always, which will allow the particular service to always be enabled. You can create your own times in the Tools > Schedules section.
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.
