VPN Virtual Private Network is an important tool to connect from the private network to the remote sitec
Basically, a VPN
virtual private network is a private network that uses a public network (usually
the Internet) to connect remote site or users together. Instead of using a dedicated,
real world connection such as leased line, a VPN virtual private network uses
"virtual" connections routed through the Internet from the company's
private network to the remote site or employee.
As the popularity
of the Internet grew, businesses turned to it as a means of extending their
own networks. First came intranets, which are password protected sites designed
for use only by company employees. Now, many companies are creating their own
VPN virtual private network to access to the remote site and distant offices.
There are two common types of VPN virtual private network. Remote access, it is a user to LAN connection used by a company that has employees who need to connect to the private network from various remote site and locations. Typically, a corporation that wishes to set up a large remote access program will outsource to an enterprise service provider (ESP). The ESP sets up a network access server (NAS) and provides the mobile users with desktop client software for their computers. The telecommuters can then dial a toll-free number to reach the NAS to access the corporate network.
