4. In the General section:
a. Enter a description name in the Policy Name Field such as “salesperson”. This name will
be used as part of the remote identifier in the VPN client configuration.
b. Set Direction/Type to Responder.
c. The Exchange Mode will automatically be set to Aggressive.
5. For Local information:
d. Select Fully Qualified Domain Name for the Local Identity Type.
e. Enter an identifier in the Remote Identity Data field that is not used by any other IKE
policies. This identifier will be used as part of the local identifier in the VPN client
configuration.
6. Specify the IKE SA parameters. These settings must be matched in the configuration of the
remote VPN client. Recommended settings are:
• Encryption Algorithm: 3DES
• Authentication Algorithm: SHA-1
• Diffie-Hellman: Group 2
• SA Lifetime: 3600 seconds
7. Enter a Pre-Shared Key that will also be configured in the VPN client.
8. XAUTH is disabled by default. To enable XAUTH, select:
• Edge Device to use this router as a VPN concentrator where one or more gateway tunnels
terminate. (If selected, you must specify the Authentication Type to be used in verifying
credentials of the remote VPN gateways.)
• IPsec Host if you want this gateway to be authenticated by the remote gateway. Enter a
Username and Password to be associated with the IKE policy. When this option is chosen,
you will need to specify the user name and password to be used in authenticating this
gateway (by the remote gateway).
9. If Edge Device was enabled, select the Authentication Type from the pull down menu which
will be used to verify account information: User Database, RADIUS-CHAP or RADIUS-PAP.
Users must be added through the User Database screen (see “User Database Configuration” on
page 5-34 or “RADIUS Client Configuration” on page 5-35).
Note: If RADIUS-PAP is selected, the router will first check the User Database to
see if the user credentials are available. If the user account is not present, the
router will then connect to the RADIUS server.
