How To Configure A Connection To VPN

You can use a virtual private network (VPN) to connect components to one network by using another network, such as the Internet. Virtual private networks do this by "tunnelling" through the Internet or another public network in a manner that provides the same security and features as a private network. With a VPN, connections across the public network can transfer data by using the routing infrastructure of the Internet, but to the user, the data seems to travel over a dedicated private link. 

Overview of a VPN

A VPN is a method of connecting to a private network (for example, your office network) by way of a public network (for example, the Internet).A VPN gives you the benefit of a dial-up connection to a dial-up server, plus the ease and flexibility of an Internet connection. Using an Internet connection permits you to connect to resources all over the world and still, in most places, connect to your office by making a local call to the nearest Internet access phone number. If you have a high-speed Internet connection such as cable or digital subscriber line (DSL) at your computer and at your office, you can communicate with your office at full Internet speed. This is much faster than any dial-up connection that uses an analog modem.

VPN's use authenticated links to make sure that only authorised users can connect to your network, and they use encryption to make sure that others cannot intercept and cannot use data that travels over the Internet. Windows XP achieves this security by using Point-to-Point Tunnelling Protocol (PPTP) or Layer Two Tunnelling Protocol (L2TP). A Tunnelling Protocol is a technology that helps make the transfer of information over the Internet more secure from one computer to another.

VPN technology also permits a corporation to connect to its branch offices or to other companies over a public network, such as the Internet, while helping to maintain secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link.Configure a VPN connection from a client computer

    1.Use one of the following methods:

        >Click Start, point to Connect To, and then click the new connection.

        >If you added a connection shortcut to the desktop, double-click the shortcut on the desktop.

    2.If you are not currently connected to the Internet, Windows offers to connect to the Internet.

    4.To disconnect from the VPN, right-click the icon for the connection, and then click Disconnect.

Note: If you cannot connect to shared resources on the remote network by computer, you can use the remote computer's IP address to connect by using UNC (\\<IP_Address>\Share_name). Edit the hosts file in the Windows\System32\Drivers\ folder, and add an entry to map the remote server's name to its IP address. Then use the computer name in a UNC connection (\\Server_name\Share_name).

Troubleshoot VPN connections

Troubleshooting VPN connection issues typically involves contacting your Internet service provider (ISP), your VPN server administrator, or your router or firewall manufacturer.When you try to connect to your VPN server, you may not be able to connect, and you may receive an error message that resembles the following:

678: The remote computer did not respond.

930: The authentication server did not respond to authentication requests in a timely fashion.

800: Unable to establish the VPN connection.

623: The system could not find the phone book entry for this connection.

720: A connection to the remote computer could not be established.

Final words

Virtual private network helps to access the websites if the websites are blocked in any of the colleges or schools and in universities.A tunnel will be formed while making use of a normal VPN. Proxy VPN will helps to redirect to the websites which are unassailable by changing the DNS of the connected network locally until the time time which we are using the VPN. Once VPN is disconnected we can't access the websites again because the primary DNS will be coming here in scenario where your Mac-address is already registered in the DNS server. Proxy VPN's are of many types and we recommend "ukvpn" proxy will be working fine to by all the websites that are blocked.
