VPN (Virtual Private Network) technology lets a computer using a public Internet connection join a private network by way of a secure “tunnel” between that machine and the network. The most common case is a business allowing its employees to connect to its work network from home or from the road.
There are two principal ways to configure VPN. The first and more-common scenario, called outgoing, is setting up a remote computer to call into the office network. The second scenario, called incoming, occurs on the network side, where a computer allows secure connections from other computers. Windows 7 comes preloaded with the Agile VPN client, which makes setting up either kind of connection relatively easy.
Step by Step: Connecting to a VPN (Outgoing)
Step 1 Click the Start button. In the search bar, type VPN and then select Set up a virtual private network (VPN) connection.
Step 2 Enter the IP address or domain name of the server to which you want to connect. If you’re connecting to a work network, your IT administrator can provide the best address.
Step 3 If you want to set up the connection, but not connnect, select Don’t connect now; otherwise, leave it blank and click Next.
Step 4 On this next screen, you can either put in your username and password, or leave it blank. You’ll be prompted for it again on the actual connection. Click Connect.
Step 5 To connect, click on the Windows network logo on the lower-right part of your screen; then select Connect under VPN Connection.
Step 6 In the Connect VPN Connection box, enter the appropriate domain and your log-in credentials; then click Connect.
Step 7 If you can’t connect, the problem could be due to the server configuration. (There are different types of VPN.) Check with your network administrator to see what kind is in use–such as PPTP–then, on the Connect VPN Connection screen, select Properties.
Step 8 Navigate to the Security tab and select the specific Type of VPN from the drop-down list. You may also have to unselect Include Windows logon domainunder the Options tab. Then click OK andConnect.
Step by Step: Building a VPN (Incoming)
Step 1 Click the Start button, and, in the search bar, type Network and Sharing.
Step 2 Click Change Adapter Settings in the left-hand menu.
Step 3 Click File, and then New Incoming Connection.
Step 4 Select the users you’d like to give access to and click Next.
Step 5 Click Through the Internet and select Next.
Step 6 Select the Internet Protocol you’d like to use. (The default TCP/IPv4–the line highlighted in the screenshot below–will work fine.)
