Inbound AH
Authentication Key Configure a key for computing the integrity check on inbound traffic
with the selected authentication algorithm. The key must be 32/40
(for MD5/SHA1) hexadecimal (0-9, A-F) characters in length. The
key value must match the corresponding outbound key on the
remote security gateway.
Outbound AH
Authentication Key Configure a key for computing the integrity check on outbound
traffic with the selected authentication algorithm. The key must be
32/40 (for MD5/SHA1) hexadecimal (0-9, A-F) characters in length.
The key value must match the corresponding inbound key on the
remote security gateway.
Inbound SPI (Hex) Enter an up to six-character hexadecimal value to identify the
inbound security association created by the AH algorithm. The
value must match the corresponding outbound SPI value configured
on the remote security gateway.
Outbound SPI (Hex) Provide an up to six-character hexadecimal value to identify the
outbound security association created by the AH algorithm. The
value must match the corresponding inbound SPI value configured
on the remote security gateway.
ESP Type ESP provides packet encryption, optional data authentication and
anti-replay services for the VPN tunnel. Use the drop-down menu
to select the ESP type. Options include:
• None - Disables ESP. The rest of the fields are not be active.
• ESP - Enables ESP for the tunnel.
• ESP with Authentication - Enables ESP with authentication.
ESP Encryption
Algorithm Select the encryption and authentication algorithms for the VPN
tunnel using the drop-down menu.
• DES - Uses the DES encryption algorithm requiring 64-bit
(16-character hexadecimal) keys.
• 3DES - Uses the 3DES encryption algorithm requiring 192-bit
(48-character hexadecimal) keys.
• AES 128-bit: - Uses the Advanced Encryption Standard
algorithm with 128-bit (32-character hexadecimal) keys.
• AES 192-bit: - Uses the Advanced Encryption Standard
algorithm with 192-bit (48-character hexadecimal) keys.
• AES 256-bit: - Uses the Advanced Encryption Standard
algorithm with 256-bit (64-character hexadecimal) keys.
