Configuring VPNs for remote access

The VPN 3000 Concentrator enters into Quick Configuration mode the first time it is powered up.

Quick Configuration is a configuration wizard that guides you through the initial configuration settings. To begin performing the 11 steps outlined above from the CLI, connect your console to the

concentrator and power on the concentrator.

As the system boots, various information is displayed on the console screen. After the system has performed the boot functions, you should see the login prompt. When prompted, supply the default administrator login name of admin and the default password, which is also admin. Note that the password is not displayed on the console screen as you type it, as shown in the following CLI output.

Setting the system time, date, and time zone

At this point, the concentrator is waiting for you to verify the current time by pressing Enter or to type in a new time. Notice that the system prompt changes to Quick to indicate that the system is waiting for you to confirm or enter data. The following example also shows the entries that are required (in boldface type) to complete the configuration of the date, time zone, and daylight-savings time support information.

Configuring the private LAN interface

The next phase of the CLI Quick Configuration steps is to configure the Private LAN interface.

This is simply a matter of setting the IP address and subnet mask information and then specifying the speed and duplex mode to use for the interface. Those steps are shown in the output, which is displayed as soon as you enter your preference for daylight-savings support.

The administrator wanted to use a 24-bit subnet mask. When he entered a Class C IP address for the interface, the system automatically brought up the 24-bit Class C default subnet mask. The administrator simply pressed Enter to accept this subnet mask setting. Also notice that the administrator explicitly set the speed of the interface to 100 Mbps and to Full Duplex rather than accepting the default automatic detection settings.

From the menu displayed at the end of the previous output display, you can see that you have the option of also configuring the Public interface. If the hardware configuration had additional interfaces, you would see menu options for configuring those interfaces, too.

The browser-based manager is the configuration tool of choice for the VPN 3000 Concentrator.

The CLI is used only to enable network connectivity so that you can communicate with the concentrator through the network from your administration workstation. Configuration of additional interfaces and all remaining concentrator settings is accomplished through the browser-based manager.

To finish the CLI initial configuration of the VPN concentrator, simply save your changes to the Config file and then exit the Quick Configuration mode.

Configuring remaining interface settings

When you click to start Quick Configuration, the VPN Manager displays the IP Interfaces screen. Notice that the screen’s title bar shows the complete path to this screen (Configuration | Quick | IP Interfaces), as it would be shown if you had worked down to this screen through the table of contents. This 3005 display shows that the Private interface is configured and operational and that the Public interface is not yet configured.
