Type a name to identify the tunnel configuration.

Select the phase 1 configuration to assign to this tunnel. See 

. The phase 1 configuration describes how remote peers or clients 

will be authenticated on this tunnel, and how the connection to the remote 

peer or client will be secured. 

If the tunnel will be included in a hub-and-spoke configuration, you may select 

the concentrator from the list. The hub must be added to the FortiGate 

configuration before it can be selected here. See 

.

Select the encryption and authentication algorithms that will be used to 

change data into encrypted code.
Add or delete encryption and authentication algorithms as required. Select a 

minimum of one and a maximum of three combinations. The remote peer 

must be configured to use at least one of the proposals that you define.
You can select any of the following symmetric-key algorithms:
•

NULL-Do not use an encryption algorithm.

DES-Digital Encryption Standard, a 64-bit block algorithm that uses a 56-
bit key.

3DES-Triple-DES, in which plain text is encrypted three times by three 
keys.

AES128-A 128-bit block algorithm that uses a 128-bit key.

AES192-A 128-bit block algorithm that uses a 192-bit key.

AES256-A 128-bit block algorithm that uses a 256-bit key.
