IPsec
1 [IPsec]
Key settings for use with IPsec can be selected as
[Auto Key Exchange] or [Manual].
Auto Key Exchange Setting
1 [IPsec SA Encryption Algorithm]
Set the IPsec SA encryption algorithm to [AES->3DES],
[AES->3DES->DES] or [AES->3DES->DES->NULL].
The specified algorithm will be checked for an
applicable encryption algorithm starting from the left.
2 [IPsec SA Authentication Algorithm]
Set the IPsec SA authentication algorithm to
[HMAC_SHA1_96] or [HMAC_SHA1_96->HMAC_MD5_96].
The specified algorithm will be checked for an
applicable authentication algorithm starting from the
left.
3 [IPsec SA Validity Period (min)]
Set the duration of validity for IPsec SA (factory default
setting is [480]).
4 [ISAKMP SA Encryption Algorithm]
Set the SA encryption algorithm for use with auto key
exchange protocol IKE to [AES->3DES] or
[AES->3DES->DES].
5 [ISAKMP SA Authentication Algorithm]
Set the SA authentication algorithm for use with auto
key exchange protocol IKE to [SHA1] or [SHA1->MD5].
6 [DH Group]
Select [Group 2] or [Group 2->Group 1] for the key
generation information that will be used in the DH
algorithm for key exchange via auto key exchange
protocol IKE.
7 [ISAKMP SA Validity Period (min)]
Set the duration of validity for ISAKMP SA (factory
default setting is [480]).
IPsec Set (Auto Key Exchange)
IPsec Sets 1 to 5 are available, and you can specify IPsec
settings for one communication device for each IPsec Set.
1 [IPsec Set]
Set IPsec Set to [Disable], [Enable in IPv4] or [Enable
in IPv6].
2 [IPsec Mode]
Set IPsec mode to [Tunnel Mode] or [Transport Mode].
3 [Destination IPv4 Address], [Destination IPv6 Address]
Enter the IP address of the connection destination.
4 [Source IPv4 Address], [Source IPv6 Address]
Enter the IP address of the source.
5 [Security Protocol]
Set the IPsec protocol to [ESP], [AH] or [ESP and AH].
If [ESP] is selected, enter only the setting items relating
to ESP.
If [AH] is selected, enter only the setting items relating
to AH.
If [ESP and AH] is selected, enter all setting items.
6 [Security Gateway IP Address (IPv4/IPv6)]
If IPsec mode is set to [Tunnel Mode] in 2, set the IP
address of the security gateway.
7 [Destination Subnet Mask Length (IPv4)], [Destination
Prefix Length (IPv6)]
This setting is required only if IPsec mode is set to
[Tunnel Mode] in 2.
If IPv6 is used, enter a desired prefix length for the
connection destination in the range of 16 to 128.
If IPv4 is used, enter a desired length in the range of 1
to 32.
[IPsec] IPsec Settings
The following can be set here.
• IPsec
Set the IPsec setting method.
• Auto Key Exchange Setting
Set auto key exchange.
• IPsec Set
IP security can be specified through auto key
exchange or manual setting with up to five
communicating devices.
