149Chapter 9 Customizing Services
When Network preferences or Internet Connect nishes importing the VPN
conguration, the user must enter an account name and may enter a password,
and whatever the user enters is saved as part of the VPN conguration upon quitting
the application. If the user saves both the name and password as part of the VPN
conguration, anyone using that computer will then be able to log in automatically for
a VPN connection to your server.
For security, you can instruct users to enter their account name but leave the password
blank, and then quit the application (System Preferences or Internet Connect). If users
don’t save a password as part of the VPN conguration on their computers, they will be
asked to log in each time they make a VPN connection to your server.
For information you can give users instructing them how to use the VPN conguration
le, see Setting Up a Mac Users VPN Connection on page 11 5 .
Changing the IP Address Range for VPN
You can use Server Preferences to change the range of addresses you want the server
to reserve for assigning to remote computers when they make a VPN connection to
the server. For example, you might make the range larger to make more IP addresses
available for VPN connections.
Important: These are addresses on the servers network, and they must not be used by
other computers or devices on the network. This range of addresses must not include
any static IP addresses in use on the network and must not overlap the range of IP
addresses that the DHCP server assigns.
