2. To configure L2TP settings, select L2TP as the tunnel type.
3. Select one of the L2TP Authentication methods. Click the drop-down list and select the authentication method that you want to use for the branch office connection.
   
   

   Note: When you change the Authentication Type, the screen immediately changes to reflect the requirements of the new authentication method. Any changes that you might have made on the Authentication part of the previous screen are lost.

   
   
4. Enter the local user ID and password for the local gateway that you are configuring.
5. Enter the user ID of the remote gateway that you are configuring.
6. Enter the password for the UID, then confirm the password to verify that you entered it correctly. If you selected a variation of MS-CHAP V2 authentication, no password is required for the Local UID.
7. Select a Compression setting. Click to enable the L2TP Microsoft Point-to-Point Compression (MPPC ) packet compression. Compression should be used when encryption is selected on analog modems. This is because encryption renders a modem's compression ineffective, and it can severely affect the performance of compressible applications. Also, data that is compressed before being transmitted makes more efficient use of lower speed network links.
8. Select the Compression/encryption stateless mode. Click to Enable or Disable this selection. This selection is not used if encryption and compression are both disabled.
9. Select an L2TP access concentrator. Use this entry to specify the L2TP Access Concentrator that you want to perform authentication between the gateway and the NAS. You can use the New L2TP Access Concentrator link to jump to the screen where you can create a new access concentrator.
10. Select an IPSec data protection level.
