Virtual Private Networks (VPNs) let you securely extend the boundaries of your
internal network and use insecure communication channels (such as the
Internet) to safely transport sensitive data. VPNs are used to allow a single user
or remote network to access the protected resources of another network.
Symantec Gateway Security 300 Series appliances support three types of VPN
tunnels: Gateway-to-Gateway, Client-to-Gateway, and wireless Client-to-
Gateway. To configure wireless Client-to-Gateway tunnels, see the Symantec
Gateway Security 300 Series Wireless Implementation Guide.
Securing your network connections using VPN technology is an important step
in ensuring the quality and integrity of your data. This section describes some
key concepts and components you need to understand to effectively configure
and use the appliance's VPN feature.
VPN tunnels can also support dynamic and static Gateway-to-Gateway
configurations, where tunnel parameters are created at each security gateway.
Both ends must have the same parameters, including secret keys, security
parameter indexes (SPIs), authentication schemes, encryption methods.
