Another way of improving the security of the PLC network and of the IP local

area network consists of installing a PPPoE server and an associated RADIUS

server. This technique is used for implementing IP “tunnels” between the computers

connected to the PLC local area network and to the Internet gateway; these clients

are authenticated on the RADIUS server.

If an intruder successfully connects to a PLC local area network, he cannot use

the local area network as long as he is not connected to the PPPoE server and to the

RADIUS server on the gateway. Therefore, the hacker’s station can neither access

other computers connected to the PLC network nor access the Internet via the PLC

network gateway.

Figure 10.19 illustrates the concept of PPPoE tunnels established between the

client computers and the Internet gateway and enabling the securing of exchanges

between the gateway (and the Internet) and these client computers.
