Configuring Address Assignment
• Don’t Require Encryption—PPTP connections may use Microsoft encryption to encrypt data (the
default). During connection setup, clients may or may not agree to use Microsoft encryption; they
will be connected in either case.
Step 3 Check L2TP to enable Layer 2 Tunneling Protocol. (This box is checked by default.)
Step 4 If you enable L2TP, click one of the radio buttons to select the encryption option:
• Require Encryption—L2TP connections must use Microsoft encryption to encrypt data. This option
requires MS-CHAP and provides maximum security. During connection setup, clients must agree to
use encryption or they will not be connected.
• Don’t Require Encryption—L2TP connections may use Microsoft encryption to encrypt data (the
default). During connection setup, clients may or may not agree to use Microsoft encryption; they
will be connected in either case.
Step 5 Check IPSec to enable remote-access user connections using Internet Protocol Security protocol. (This
box is checked by default.) This option supports only remote-access IPSec connections from the VPN
3000 Client or a similar protocol-compliant client. To configure IPSec LAN-to-LAN connections, see
Configuration | System | Tunneling Protocols | IPSec LAN-to-LAN under regular system configuration.
Step 6 Check WebVPN to enable remote-access user connections via SSL using a web browser or e-mail client.
Step 7 Click Continue to proceed.
If you enable none of the protocols, skip to the section on Changing Admin Password, page 3-21.
If you enable at least one protocol, continue to the next section.
