Authentication Key Enter 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 must match the
corresponding inbound key on the remote security
gateway.
Inbound SPI (Hex) Define an (up to) six-character (maximum) hexadecimal
value to identify the inbound security association created
by the encryption algorithm. The value must match the
corresponding outbound SPI value configured on the
remote security gateway.
Outbound SPI
(Hex) Enter an (up to) six-character (maximum) hexadecimal
value to identify the outbound security association created
