Introduction to VPNs
A VPN is a connection between two endpoints in different networks to allow
private data to be sent securely over a shared or public network, such as the
Internet. This tunnel establishes a private network that can send data securely
between these two locations or networks. A VPN tunnel uses industry-standard
encryption and authentication techniques to secure the data sent between the
two networks. It can be used to create secure networks linking a central office
with remote offices, telecommuters, and/or professionals on the road.
There are several ways to create a VPN connection:
• Site to Site VPN (Gateway To Gateway), page 123
• Remote Access (Client To Gateway), page 123
• Remote Access with Cisco QuickVPN, page 125
• Remote Access with PPTP, page 125
