set vpn

inbound_authentication={nonemd5sha1}

The optional authentication algorithm, used with the associated authentication key specified by the “inbound_auth_key” option, to authorize access on the VPN tunnel for inbound traffic.

none

No authentication algorithm is used.

md5

MD5 authentication algorithm, which uses 128-bit keys.

sha1

SHA1 authentication algorithm, which uses 160-bit keys.

inbound_auth_key={ascii keyhex key}

The authentication key for inbound traffic, according to the authentication algorithm specified by the “inbound_authentication” option. The authentication key may be specified as an ASCII value using alpha-numeric characters or may be specified as a hexadecimal value prefixed by “0x”. The following table lists the associated lengths of the authentication keys based on the authentication algorithm.

Algorithm	Size	Key Length
		ASCII	Hexadecimal
MD5	128-bit	16	32
SHA1	160-bit	20	40

inbound_encryption={nonedes3desaes}

The optional encryption algorithm used with the associated encryption key specified by the “inbound_enc_key” option to encrypt data on the VPN tunnel for inbound traffic.

none

No encryption algorithm is used.

des

DES encryption algorithm, which uses 64-bit keys.

3des

3DES encryption algorithm, which uses 192-bit keys.

aes

AES encryption algorithm, which uses 128-bit keys.
