124 Appendix B Setup Example

7 Click LDAP to configure DHCP to identify the server you are configuring as the source

of directory information for clients who are served dynamic IP addresses.

The server you are setting up is automatically identified in the Server Name field,

because you set up a master LDAP domain on the server when you used Server

Assistant. Other settings are optional for this example.

8 Click WINS to configure DHCP to serve Windows-specific settings to clients who are

served dynamic IP addresses.

Supply these values:

WINS/NBNS Primary Server: 198.168.0.1

NBDD Node Type: Broadcast (b-node)

9 Click Save, then click Start Service.

Step 6: Set up NAT service

1 In Server Admin, select NAT in the Computers & Services list.

2 Click Settings.

3 Select the external interface from the “Share your connection from” pop-up menu.

4 Click Save, then click Start Service.

Step 7: Set up VPN service

1 In Server Admin, select VPN in the Computers & Services list.

2 Click Settings.

3 Enable L2TP over IPSec (Layer Two Tunneling Protocol, Secure Internet Protocol) for

Mac OS X version 10.3 computer users, Linux or UNIX workstation users, and Windows

XP users. While PPTP, described in the next step, can also be used, L2TP provides the

greatest security because it runs over IPSec.

Specify the shared secret by typing a string in “IPsec shared secret”. Enter a string that

isn’t intuitive. For example, specify digits, symbols, and uppercase and lowercase

characters in unusual combinations. The recommended string length is 8 to 12

characters.

To restrict VPN connections to members of a group, select “Restrict access to group”

and select the group. Click the Users & Groups button to open a drawer from which

you can drag a group name into the field.

Enter a starting and ending IP address to indicate which addresses the VPN server can

assign to clients. Avoid addresses the DHCP server is set up to serve. Also avoid

addresses you specify if you enable PPTP.
