PPPoE cannot be used with HA
For reasons connected with the way IP addresses are shared in a NetDefendOS high availability
cluster, PPPoE will not operate correctly. It should there not be configured with HA.

Example 3.11. Configuring a PPPoE Client
This example shows how to configure a PPPoE client on the wan interface with traffic routed over PPPoE.
CLI

Then enter:
•
Name: PPPoEClient
•
Physical Interface: wan
•

3.3.5. GRE Tunnels
Overview
The Generic Router Encapsulation (GRE) protocol is a simple, encapsulating protocol that can be
used whenever there is a need to tunnel traffic across networks and/or through network devices.
GRE does not provide any security features but this means that its use has extremely low overhead.

GRE does not provide any security features but this means that its use has extremely low overhead.
Using GRE
GRE is typically used to provide a method of connecting two networks together across a third
network such as the Internet. The two networks being connected together communicate with a
common protocol which is tunneled using GRE through the intervening network. Examples of GRE
usage are:
