FIELD DESCRIPTION
Active Protocol Press [SPACE BAR] to choose from ESP Tunnel, ESP Transport, AH Tunnel or
AH Transport and then press [ENTER]. Choosing an ESP combination causes the
AH Setup fields to be non-applicable (N/A)
ESP Setup The ESP Setup fields are N/A if you chose an AH Active Protocol.
SPI (Decimal) The SPI must be unique and from one to four integers ("0" to "9").
Encryption
Algorithm
Press [SPACE BAR] to choose from NULL, DES, 3DES or AES and then press
[ENTER]. Fill in the Key1 field below when you choose DES and fill in fields Key1 to
Key3 when you choose 3DES. Select NULL to set up a tunnel without encryption.
When you select NULL, you do not enter any encryption keys.
Key1 Enter a unique eight-character key. Any character may be used, including spaces,
but trailing spaces are truncated.
Fill in the Key1 field when you choose DES and fill in fields Key1 to Key3 when you
choose 3DES.
Key2 Enter a unique eight-character key. It can be comprised of any character including
spaces (but trailing spaces are truncated).
Key3 Enter a unique eight-character key. It can be comprised of any character including
spaces (but trailing spaces are truncated).
Authentication
Algorithm
Press [SPACE BAR] to choose from MD5 or SHA1 and then press [ENTER].
Key Enter the authentication key to be used by IPSec if applicable. The key must be
unique. Enter 16 characters for MD5 authentication and 20 characters for SHA-1
authentication. Any character may be used, including spaces, but trailing spaces are
truncated.
AH Setup The AH Setup fields are N/A if you chose an ESP Active Protocol.
