Virtual IPs

Running the DFL-500 in NAT mode hides the addresses of the computers on your internal network from the
Internet. To provide Internet access to a server on your internal network, you must make an association
between the Internet address of the server and the actual IP address of the computer on the internal network
that is running the server. This association is called a Virtual IP.
Once you have created a Virtual IP, you can add Incoming policies to allow access to the server by adding
the virtual IP to the Destination address of the policy.

Adding Virtual IPs

•
To add a Virtual IP:
•
Go to Firewall > Virtual IP .
•
Click New to add the Virtual IP.
•
Enter a Name for the Virtual IP.
The name can contain numbers (0-9) and upper and lower case letters (A-Z, a-z), and the special
characters - and _. Spaces and the @ character are not allowed.
•
In the External IP Address field, enter the Internet IP address of the server.
This must be a static IP address obtained from your ISP for this purpose and must not be the same as the
external address of the DFL-500. However, your ISP must route this address to the external IP address of
the DFL-500.
•
In the Map to IP field, enter the actual IP address of the web server.
•
Click OK to save the Virtual IP.
•
Repeat these steps to add Virtual IPs for all of your internet servers.
