Step 8 Define an Incoming SPI and an Outgoing SPI. The SPIs are hexadecimal
(0123456789abcedf) and can range from 3 to 8 characters in length.
Caution Each Security Association must have unique SPIs; no two Security Associations can share
the same SPIs. However, each Security Association Incoming SPI can be the same as the
Outgoing SPI.
Step 9 The default values for Protocol, Phase 2 Encryption, and Phase 2 Authentication are
acceptable for most VPN SA configurations.
Note The values for Protocol, Phase 2 Encryption, and Phase 2 Authentication must match
the values on the remote SonicWALL.
Step 10 Enter a 16 character hexadecimal encryption key in the Encryption Key field or use the default
value. This encryption key is used to configure the remote SonicWALL encryption key,
therefore, write it down to use when configuring the SonicWALL.
Step 11 Enter a 32 character hexadecimal authentication key in the Authentication Key field or use
the default value. Write down the key to use while configuring the SonicWALL settings.
