Setting up the L2TP VPN server with IPsec encryption (PSK)

1. Log into your router management page (see “Access your router management page”

on page 7).

2. Click on System and click L2TP Server Setup.

3. For the Mode, select the Enable option to enable the L2TP server.

4. In the Local IP Address field, enter an IP address other than the LAN IP address.

(Default LAN IP: 192.168.10.1) (e.g. 192.168.80.1)

Note: Entering an IP address different from the LAN IP address as the Local IP of the L2TP

server ensures your L2TP VPN clients are able to access the Internet and the router LAN

network via full tunneling. If the LAN IP address is entered, L2TP VPN clients will be

allowed to access router LAN and not the Internet.

5. In the Remote Start/End IP Address fields, enter an IP address range (within the same

Local IP Address subnet range) to assign to L2TP VPN clients.

In this example, we assigned 192.168.80.1 as the Local IP Address for the L2TP server so

we will assign a range such as 192.168.80.10-192.168.80.20.

6. Under L2TP Over IPSec Settings, for the Mode, select Enable.

7. Enter the Pre-shared Key for IPsec encryption.

8. Click the WAN ID drop-down list to select the correct WAN interface for the L2TP over

IPsec server.

9. Click Save at the bottom.

10. Click on System, click on PPTP/L2TP Account Setup, and click Create Account.
