PPPoE

PPPoE lets a network client interact with a service provider’s equipment, such as

a broadband modem—most often xDSL—to achieve access to high-speed data

networks. It relies on the Ethernet and PPP standards. It uses an authentication

strategy that includes a username and password to create a PPPoE session from

the VPN 3002 to your ISP Access Concentrator.

PPPoE is a VPN 3002 feature, transparent to the central-site Concentrator to

which the VPN 3002 connects. To use PPPoE, for the VPN 3002 public interface

you must:

• Enable PPPoE.

• Supply a username and password.

UDP NAT/FW Transparent IPSec

UDP NAT/FW Transparent IPSec enables secure transmission between the VPN

3002 Hardware Client and the central-site Concentrator through a device, such as

a firewall, that is performing Network Address Translation (NAT).

Using this feature encapsulates encrypted data traffic within UDP packets. The

VPN 3002 also sends keepalives frequently, ensuring that the mappings on the

NAT device are kept active.

While you do not have to configure this feature on the VPN 3002, the following

requirements do apply. To use IPSec through NAT:

• You must upgrade both the central-site Concentrator and the VPN 3002 to

Release 3.0.2 or higher.
