IPsec Settings (IPsec)
If [ESP] or [ESP and AH] was set under [Security Protocol] in (5), the following items must be
set.
(8) [SA ESP Encryption Algorithm]
Select [AES], [3DES], [DES] or [NULL] as the ESP encryption algorithm according to the
encryption algorithm supported by the device to connect to.
Normally [AES] or [3DES] is recommended.
(9) [SA ESP Authentication Algorithm]
Select [HMAC_SHA1_96], [HMAC_MD5_96] or [No Authentication]as the ESP authentication
algorithm according to the authentication algorithm supported by the device to connect to.
If [ESP] is used alone, [No Authentication] cannot be selected.
(10) [SA ESP Encryption key (outbound)]
Set the SA encryption key for outbound . If [AES], [3DES] or [DES] was selected in (8), set a
128-bit, 192-bit or 64-bit hexadecimal, respectively. [This item need not be set if [NULL] was
selected.
(11) [SA ESP Authentication key (outbound)]
Set the SA authentication key for outbound . If [HMAC_SHA1_96] or [HMAC_MD5_96] was
set in (9), set a 160-bit or 128-bit hexadecimal, respectively. This item need not be set if [No
Authentication] was selected.
(12) [SA ESP SPI (outbound)]
Set the SA SPI value for outbound. Set a desired value in a range of 256 to 4294967295.
(13) [SA ESP Encryption key (inbound)]
Set the SA encryption key for inbound. If [AES], [3DES] or [DES] was selected in (8), set a
128-bit, 192-bit or 64-bit hexadecimal, respectively. This item need not be set if [NULL] was
selected.
