Defining a VPN Security Association
When you click New or Modify from the Security Associations window, the VPN
Properties window appears. This window is used to add or modify VPN
associations. The window contains four tabs that are used to enter distinct
information about a VPN association.
Configuring the General tab
The General tab is used to enter basic information about the VPN association.
To configure the General tab, follow the steps below.
1 In the Name field, type the name of this VPN.
2 In the Enabled field, select Yes to enable this VPN association, or select No
to disable it.
3 In the Encapsulation field, select one of the following:
• Tunnel—The more popular form of VPN encapsulation. Both the data
and the source and destination IP addresses are encrypted within the
encapsulated payload.
• Transport—The native form of VPN. Transport mode encrypts the data
but the source and destination IP addresses are not concealed.
See “Transport mode vs. tunnel mode” on page 397 for a more detailed
explanation of these terms.
4 In the Burb drop-down list, select the burb to which you want to assign this
VPN. The Sidewinder G2 terminates each VPN in a burb so that access
rules may be applied to the VPN.
