9.4. PPPoE 63 PPPoE interface Since the PPPoE protocol runs PPP over Ethernet, the firewall needs to use one of the normal Ethernet interfaces to run the PPPoE tunnel over. Each PPPoE Tunnel is interpreted as a logical interface by the firewall, with the same filtering, traffic shaping and configuration capabilities as regular interfaces. The network traffic coming from the PPPoE tunnel will be transferred to the firewall ruleset for evaluation. The source interface of the network traffic is referred to the name of the associated PPPoE Tunnel in the firewall. The same is true for traffic coming from the opposite direction, that is, going into a PPPoE tunnel. Furthermore a Route has to be defined, so the firewall knows what IP addresses should be accepted and sent through the PPPoE tunnel. PPPoE can use a service name to distinguish between different servers on the same Ethernet network. IP address information PPPoE uses automatic IP address allocation which is similar to DHCP. When the firewall receives this IP address information from the ISP, it needs to store it in a network object with symbolic host/network names, in order to establish the PPP connection. User authentication If user authentication is required by the ISP, we can set in the firewall the user name and password for logging on to the PPPoE server. Dial on demand If dial-on-demand is enabled, the PPPoE connection will only be up when there is traffic on the PPPoE interface. It is possible to configure how the firewall should sense activity on the interface, either on outgoing traffic, incoming traffic or both. Also configurable is the time to wait with no activity before the tunnel is disconnected. D-Link Firewalls User's Guide
