Ricoh C242SF Drop IP packets are discarded, Received, IKE Settings, Gateways such as VPN devices

8. Configuring the Machine Using Web Image Monitor

	Item	Description
	Action	Specify how the IP packets are processed from the following:
		• [Allow]: IP packets are both sent and received without IPsec applied to
		them.
		• [Drop]: IP packets are discarded.
		• [Require Security]: IPsec is applied to IP packets that are both sent and

	IPsec Settings
	Item	Description
	Encapsulation Type	Specify the encapsulation type from the following:
		• [Transport]: Select this mode to secure only the payload section of
		each IP packet when communicating with IPsec compliant devices.
		• [Tunnel]: Select this mode to secure every section of each IP packet.
		We recommend this type for communication between security
		gateways (such as VPN devices).
8	Security Protocol	Select the security protocol from the following:
		• [AH]: Establishes secure communication that supports authentication
		only.
		• [ESP]: Establishes secure communication that supports both
		authentication and data encryption.
		• [ESP&AH]: Establishes secure communication that supports both data
		encryption and authentication of packets, including packet headers.
		Note that you cannot specify this protocol when [Tunnel] is selected
		for [Encapsulation Type].
	Authentication	Specify the authentication algorithm to be applied when [AH] or [ESP&AH]
	Algorithm for AH	is selected for [Security Protocol] from the following:
		[MD5], [SHA1]
	Encryption Algorithm	Specify the encryption algorithm to be applied when [ESP] or [ESP&AH] is
	for ESP	selected for [Security Protocol] from the following:
		[None], [DES], [3DES], [AES-128], [AES-192], [AES-256]
