Choosing either of the top two checkboxes means that the Encapsulating Security Payload (ESP) header will be used to encrypt and authenticate packets.

Choosing either of the bottom two checkboxes specifies that the Authentica- tion Header (AH) will be used to authenticate packets.

Encryption

This set of checkboxes specifies the encryption algorithm to be used for the tunnel session.

DES (Data Encryption Standard) uses a 56-bit key to scramble the data. 3DES uses three different keys and three applications of the DES algorithm to scramble the data.

ϖNote: You may choose only one authentication and one encryption method. The default setting of ESP (MD5,DES) is recommended for most setups.
