VPN Menu
The Virtual Private Network (VPN) menu (Figure 3-34) enables you to configure a
connection between the CPE and a VPN, e.g., to access a corporate network when
telecommuting for work. You can enable a Layer 2 Tunneling Protocol (L2TP) gateway or
a Layer 2 network connection to the VPN.

3.5.1 IPSec
The IP security (IPSec) network protocol suite is used between 2 communication points
across the IP network. The protocols provide data authentication, integrity, and
confidentiality protection services. They are needed for secure key exchange and key
management between the two network entities.
The top of the IPSec window is where you can add one or more security policies (Figure
3-35). The status of each policy you create will display in the lower half of the window.
Figure 3-35 IPSec
To configure an IPSec policy for this CPE, select the ADD POLICY button (Figure 3-36). Enter
the policy name, remote gateway, local and remote subnets, and pre-shared key for the
VPN connection. The Advance Settings offer additional parameters such as key exchange
version, IKE encryption method, etc. Refer to Table 3-5.
