Figure 8-67: Manual Key Definition
Security Parameter Index (SPI): (HEX, 100 - FFFFFFFF) A 32 bit value that
together with an IP address and a security protocol, uniquely identifies a particular
security association. The local and remote values must be coordinated with their
respective values on the IPSec peer.
Use Different Encryption Keys Selecting this option allows you to define both
local and remote algorithm keys when defining the IPSec protocol (in the next sec-
tion).
IPSec Protocol Select between the ESP and AH IPSec protocols. The screen
will refresh accordingly:
 ESP – Select the encryption and authentication algorithms, and enter the algo-
rithm keys in hexadecimal representation.
 AH – Select the hash algorithm, and enter the algorithm key in hexadecimal
representation.
Click 'OK' to save the settings.
8.4.1.4 IPSec Gateway-to-Host Connection Scenario
In order to create an IPSec connection between Watson and a Windows host, you
need to configure both the gateway and the host. This section describes both Wat-
son's configuration and a Windows XP client configuration.
