Configuring VPN in Windows

There are two steps:
* Set up one computer to share files (server).
* Set up another computer to access them (client).
Begin by setting up the server:
Open Internet Explorer and go to www.whatismyip.com. Write down the IP address. You will need it to configure the client.

1. Click the Start button and click Run.
2. Type control and hit Enter.
3. Click Network and Internet Connections.
4. Click Network Connections .
5. Click Create a New Connection, which is the first option on the left toolbar.
6. The New Connection Wizard will open. Click Next.
7. Choose Set up an advanced connection, the last element on the list. Click Next .
8. Choose Accept incoming connections. Click Next.
9. You will see the Devices for Incoming Connections screen.
10. Do not select anything on this screen. Click Next.
11. Select Allow virtual private connections. Click Next.
12. Select to whom you want to give access. Click Next. If a user is not listed, you will have to add an account. See "Related Wikihows" for more information.
13. Do not change anything on the Networking Software screen. Click Next.
That's it! Your computer is now set up to allow for VPNs. Click Finish to complete the wizard.
Now proceed to connect the client:

1. Click the Start button and click Run.
2. Type control and hit Enter.
3. Click Network and Internet Connections.
4. Click Network Connections.
5. Click Create a New Connection, which is the first option on the left toolbar.
6. The New Connection Wizard will open. Click Next.
7. Select Connect to the network at my workplace and click Next.
8. Select Virtual Private Network connection and click Next.
9. Type the name of your network in the blank box. Click Next.
10. Enter the IP address you wrote down earlier and click Next.
11. Select Add a shortcut to this connection to my desktop and click Finish.

Tips :

1. Both computers must be connected to the internet.
2. The user name and password must be entered exactly as you saved them.
3. The IP address must be written exactly as listed on the screen.
4. If the VPN doesn't work, turn off your firewall.

Warnings :

Do not give access to the "guest" account. It does not require a password, allowing anyone to access the VPN.
