After you change the secret here, all VPN users must make the same change in their
VPN congurations. For information about making this change, see “Setting Up a User’s
VPN Connection Manually” on page 11 7 .
Creating a VPN Conguration File
You can use Server Preferences to generate a le that Mac users can open to create a
VPN conguration automatically. After creating the VPN conguration, a user can make
a VPN connection to the server and its network via the Internet. The conguration le
works with Mac OS X v10.3 or later.
To generate a VPN conguration le:
1 In the VPN pane of Server Preferences, click Save As, select a location for the VPN
conguration le, and click Save.
2 Distribute the saved conguration le to users who need to set up a VPN conguration
on their Macs.
To set up a Mac, a user simply opens the VPN conguration le you generated. Opening
this le opens either the Network pane of System Preferences or Internet Connect
(depending on the Mac OS X version), and then imports a VPN conguration with all
information necessary to make a VPN connection except the name and password of a
user account on the server. If Internet Connect asks the user where to put the imported
conguration, the user should select VPN (L2TP). The user should not select VPN (PPTP)
or any other option.
