6.8.1.1 Editing an Existing Transform Set
If the attributes of an existing transform set no longer lend themselves as useful, consider editing the
transform set to be relevant with the needs of existing VPN peers.
To edit the attributes of an existing transform set:
1. Select Security > IPSec VPN from the main menu tree.
2. Click the Configuration tab.
3. Select an existing transform set and click the Edit button.
Name Displays a transform set identifier used to differentiate transform sets. The
index is helpful when transform sets with similar attributes need to be revised
or discarded.
AH Authentication
Scheme
Displays the AH Transform Authentication scheme used with the index.
Options include:
• None - No AH authentication is used.
• AH-MD5-HMAC - AH with the MD5 (HMAC variant) authentication
algorithm.
• AH-SHA-HMAC - AH with the SHA (HMAC variant) authentication
algorithm.
ESP Encryption
Scheme
Displays the ESP Encryption Transform used with the index. Options include:
• None - No ESP encryption is used with the transform set.
• ESP-DES - ESP with the 56-bit DES encryption algorithm.
• ESP-3DES - ESP with 3DES, ESP with AES.
• ESP-AES - ESP with 3DES, ESP with AES (128 bit key).
• ESP-AES 192 - ESP with 3DES, ESP with AES (192 bit key).
