VPN

3 types of VPN:

• Remote access - allow remote users like telecommuters to securely access the corporate network wherever and whenever they need to.


• Site to site - or intranet VPNs, allow a company to connect its remote sites to the corporate backbone securely over a public medium like the Internet instead of requiring more expensive WAN connections like Frame Relay.


• Extranet - allow an organization’s suppliers, partners, and customers to be connected to the corporate network in a limited way for business-to-business (B2B) communications.
