Testing the VPN Concentrator
To test if you are able to connect to the VPN Concentrator and reach the private network, it is not necessary to install a software client. You can use either of the following methods.
•
On a remote PC, connect to an ISP and use PPTP to create a secure tunnel through the Internet to the VPN Concentrator's public interface.
•Connect a PC to the network on the public side of the VPN Concentrator. Use Microsoft Dial-Up Networking to create a tunnel to the public interface of the VPN Concentrator.
This example steps you through the latter method. It uses Microsoft Dial-Up Networking on Windows 2000. If you are using a different operating system, your procedure might differ from the one shown here.
Note These instructions describe a typical installation. Please consult your ISP and your network system administrator for specific settings and instructions.
Before You Begin
To set up the test, follow these steps.
Step 1 Configure the VPN Concentrator with the following settings:
•Ethernet 2 (Public) interface with appropriate IP address (for example, 192.168.12.34) and default public filter.
•Appropriate DNS server, domain name, and default gateway.
•PPTP tunneling protocol with encryption required (MSCHAP).
•Address assignment from an appropriate configured pool of IP addresses.
•User authentication from the internal server.
•Client username (for example, simonz) and password (for example, 9se7pt14) added to the internal server user database.
Step 2 Connect a Windows 2000 PC to your network on the public side of the VPN Concentrator.
