You may recall that we had to create a special security group for any user who is going to be accessing the network over the VPN connection. Therefore, I am assuming your remote users have been added to the necessary group and your client computers already have Internet access.
To allow a Windows XP client computer to access your private network, you must tell it to use a VPN connection.
- To do so, open the Control Panel and select the Network and Internet Connections option.
- Select the Create A Connection to the Network At Your Workplace option.
- Windows will now ask you if you want to create a dial-up connection or a VPN connection. Select the VPN option and click Next.
- At this point, you will see the Company Name prompt. Here you can enter the name of your company, the name of the server that you are connecting to, or anything else to describe the connection.
- Click Next. You will be prompted to enter the IP address of the server that you are connecting to. This will be the external IP address (the one connected to the Internet) of your VPN server.
- Click Next again, followed by Finish to create your connection.
