[Select Algorithm]Select the [ESP], [ESP (AES-GCM)], or [AH (SHA1)] check box(es) depending on the IPSec header and thealgorithm used. AES-GCM is an algorithm for both authentication and encryption. If [ESP] is selected, alsoselect algorithms for authentication and encryption from the [ESP Authentication] and [ESP Encryption] drop-down lists.[ESP Authentication] To enable the ESP authentication, select [SHA1] for the hash algorithm. Select [Do NotUse] if you want to disable the ESP authentication.[ESP Encryption] Select the encryption algorithm for ESP. You can select [NULL] if you do not want tospecify the algorithm, or select [Do Not Use] if you want to disable the ESP encryption.[Connection Mode]The connection mode of IPSec is displayed. The machine supports transport mode, in which the payloads ofIP packets are encrypted. Tunnel mode, in which whole IP packets (headers and payloads) are encapsulatedis not available.11 Click [OK].● If you need to register an additional security policy, return to step 6.12 Arrange the order of policies listed under [Registered IPSec Policies].● Policies are applied from one at the highest position to the lowest. Click [Up] or [Down] to move a policy up ordown the order.Editing a policy● Click the corresponding text link under [Policy Name] for the edit screen.Deleting a policy● Click [Delete] on the right of the policy name you want to delete click [OK].13 Restart the machine.● Turn OFF the machine, wait for at least 10 seconds, and turn it back ON.Using the operation panel● You can also enable or disable IPSec communication from Use IPSec(P. 365)Security266
