Authentication Algorithm
If you enable AH, then select the authentication algorithm:
• MD5 — the default
• SHA1 — more secure
Enter the keys in the fields provided. For MD5, the keys should be 16
characters. For SHA-1, the keys should be 20 characters.
Key - In
Enter the keys.
• For MD5, the keys should be 16 characters.
• For SHA-1, the keys should be 20 characters.
Any value is acceptable, provided the remote VPN endpoint has the same
value in its Authentication Algorithm Key - Out field.
Key - Out
Enter the keys in the fields provided.
• For MD5, the keys should be 16 characters.
• For SHA-1, the keys should be 20 characters.
Any value is acceptable, provided the remote VPN endpoint has the same
value in its Authentication Algorithm Key - In field.
Encapsulated Security
Payload (ESP) Configuration
ESP provides security for the payload (data) sent through the VPN tunnel.
Generally, you will want to enable both encryption and authentication.
when you use ESP. Two ESP modes are available:
• Plain ESP encryption
• ESP encryption with authentication
These settings must match the remote VPN endpoint.
SPI - Incoming
Enter a hexadecimal value (3 - 8 chars). Any value is acceptable, provided
the remote VPN endpoint has the same value in its Outgoing SPI field.
SPI - Outgoing
Enter a hexadecimal value (3 - 8 chars). Any value is acceptable, provided
the remote VPN endpoint has the same value in its Incoming SPI field.
Enable Encryption
Use this check box to enable or disable ESP Encryption.
Encryption Algorithm
If you enable ESP Encryption, then select the Encryption Algorithm:
• DES — the default
• 3DES — more secure
Key - In
Enter the key in the fields provided.
• For DES, the key should be eight characters.
• For 3DES, the key should be 24 characters.
Any value is acceptable, provided the remote VPN endpoint has the same
value in its Encryption Algorithm Key - Out field.
Key - Out
Enter the key in the fields provided.
• For DES, the key should be eight characters.
• For 3DES, the key should be 24 characters.
Any value is acceptable, provided the remote VPN endpoint has the same
value in its Encryption Algorithm Key - In field.
