To change the password for the unit (highly recommended for security reasons) simply check the “Change Password Box” and enter the new password into each of the two boxes. Press “Save” when you are done.

Virtual Server

Select the Virtual Server tab to set the Virtual Server settings, see figure 8. Virtual Server will allow you to open blocked ports in the DI-701 and reroute incoming traffic to specific machines on your internal network.

Certain applications use ports that can be seen as a security threat. The Virtual Server menu allows you to open these ports manually to allow a client computer to still access services that would otherwise be blocked. Additionally this reroutes port calls from the Internet to a specified client. This would allow individual FTP, Web, and other servers to be accessed from the Internet using the IP address of the DI-701. At the same time, other ports would be blocked protecting the servers from various attacks.

The setup is very simple, enter the port number and IP address in the provided fields and press Add and then Save. If you are not sure of the local client’s IP address, use the browse button to choose the computer by name. The DI-701 will reboot, you must reboot all client machines (or renew their IP addresses). In figure 8 the example shown is opens port 80 for one of the local machines. This would reroute any outside attempt to access a web page at the DI-701’s IP address to the local client. For normal use, ports typically do not need to be opened. Standard services are already recognized and allowed to pass by the DI-701. See the troubleshooting section (“My Internet application won’t work”) for additional information on opening ports.
