2Click on the Authentication tab.

Figure 124 shows the authentication parameters available for each tunnel protocol.

3Do one of the following:

–Choose IPSec from the Protocol pull down menu.

-Use the information in Table 18 to select the IPSec Signature Algorithm that determines how IPSec packets exchanged between the ANG and Aurorean users are signed and verified.

-Use Table 18 to select the Time Period and Data Transferred values which set how long the key lifetime should last in terms of time elapsed or kilobytes amassed.

-Click Apply.

–For PPTP, no additional work is required. Unlike IPSec, PPTP does not authenticate individual packets; instead, PPTP relies on user authentication using MS-CHAP. After the remote user is authenticated, all PPTP packets are allowed access.
