	Key	Select one of the following options for the key exchange method:
	(continued)Management 		Auto (IKE)
			– Encryption: The Encryption method determines the length of the key used
			to encrypt/decrypt ESP packets. Notice that both sides must use the same
			method.
			– Authentication: The Authentication method authenticates the
			Encapsulating Security Payload (ESP) packets. Select MD5 or SHA. Notice
			that both sides (VPN endpoints) must use the same method.
			 MD5: A one-way hashing algorithm that produces a 128-bit digest
			 SHA: A one-way hashing algorithm that produces a 160-bit digest
			– Perfect Forward Secrecy (PFS): If PFS is enabled, IKE Phase 2 negotiation
			will generate new key material for IP traffic encryption and authentication.
			Note that both sides must have PFS enabled.
			– Pre-Shared Key: IKE uses the Pre-Shared Key to authenticate the remote
			IKE peer. Both character and hexadecimal values are acceptable in this
			field, e.g., "My_@123" or "0x4d795f40313233". Note that both sides must use
			the same Pre-Shared Key.
			– Key Lifetime: This field specifies the lifetime of the IKE generated key. If
			the time expires, a new key will be renegotiated automatically. The Key
			Lifetime may range from 300 to 100,000,000 seconds. The default lifetime is
			3600 seconds.
			Manual
			– Encryption: The Encryption method determines the length of the key used
			to encrypt/decrypt ESP packets. Notice that both sides must use the same
			method.
			– Encryption Key: This field specifies a key used to encrypt and decrypt IP
			traffic. Both character and hexadecimal values are acceptable in this field.
			Note that both sides must use the same Encryption Key.
			– Authentication: The Authentication method authenticates the
			Encapsulating Security Payload (ESP) packets. Select MD5 or SHA. Notice
			that both sides (VPN endpoints) must use the same method.
			 MD5: A one-way hashing algorithm that produces a 128-bit digest
			 SHA: A one-way hashing algorithm that produces a 160-bit digest
			– Authentication Key: This field specifies a key used to authenticate IP
			traffic. Both character and hexadecimal values are acceptable in this field.
			Note that both sides must use the same Authentication Key.
			– Inbound SPI/Outbound SPI: The Security Parameter Index (SPI) is carried
			in the ESP header. This enables the receiver to select the SA, under which a
			packet should be processed. The SPI is a 32-bit value. Both decimal and
			hexadecimal values are acceptable. e.g., "987654321" or "0x3ade68b1". Each
			tunnel must have a unique Inbound SPI and Outbound SPI. No two tunnels
			share the same SPI. Note that the Inbound SPI must match the remote
			gateway's Outbound SPI, and vice versa.
