Scenario: Site-to-Site VPN
Configuration
This chapter describes how to use the adaptive security appliance to create a
site-to-site VPN.
Site-to-site VPN features provided by the adaptive security appliance enable
businesses to extend their networks across low-cost public Internet connections to
business partners and remote offices worldwide while maintaining their network
security. A VPN connection enables you to send data from one location to another
over a secure connection, or tunnel, first by authenticating both ends of the
connection, and then by automatically encrypting all data sent between the two
sites.
