ESP Configuration. ESP (Encapsulating Security Payload) provides security for the payload

(data) sent through the VPN tunnel.

SPI—enter the required security policy indexes (SPIs). Each policy must have unique SPIs. These

settings must match the remote VPN endpoint. The "in" setting here must match the "out" setting

on the remote VPN endpoint, and the "out" setting here must match the "in" setting on the remote

VPN endpoint.

Encryption—select the desired Encryption Algorithm, and enter the key in the field provided. For

3DES, the keys should be 24 ASCII characters and for DES, the keys should be 8 ASCII

characters.

• DES—the Data Encryption Standard (DES) processes input data that is 64 bits wide,

encrypting these values using a 56 bit key. Faster but less secure than 3DES.

• 3DES—(Triple DES) achieves a higher level of security by encrypting the data three times

using DES with three different, unrelated keys.

Authentication—select the desired SHA-1 or MD5 Authentication Algorithm, and enter the key

in the field provided. For MD5, the keys should be 16 ASCII characters. For SHA-1, the keys

should be 20 ASCII characters.

• MD5—128 bits, faster but less secure.

• SHA-1 (default)—160 bits, slower but more secure.
