Troubleshooting

Each direction requires a separate key. The encryption or hash algorithm that you selected when 
enabling manual keys determines the exact key length. For a list of these key lengths, go to Enter 
manual keys.

1.

In the Security Policy Editor, in the Network Security Policy list, expand the specific secure 
connection .

2.

For this connection, click My Identity.

3.

In the Select Certificate box, in the My Identity group, click None.

4.

For the selected connection, expand Security Policy.

5.

In the right pane, in the Select Phase 1 Negotiation Mode group, click Use Manual Keys.

6.

In the Network Security Policy list, expand Key Exchange (Phase 2). 

7.

Click the specific proposal.

8.

In the IPSec Protocols group, Encapsulation Protocol (ESP) and Authentication Protocol 
(AH) are mutually exclusive check boxes:

•

To encrypt and authenticate the data, select the Encapsulation Protocol (ESP) check box. 

a.

In the Encryption Algorithm box, click an option:

–

For minimal security, DES 

–

For medium security, Triple-DES (the default)

–

For maximum security, AES-128, AES-192, or AES-256

–

For no security, Null 

Record your selection; you need it to determine the length of the key for the ESP 
Encryption Key box when entering inbound and outbound keys.

b.

In the Hash Algorithm box, click an option:

inbound key

<-->

outbound key

outbound key

<-->

inbound key
