As the router plays a role to manage and further protect its LAN, it interconnects groups of
host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the
Vigor router. The router itself will also use the default private IP address: 192.168.1.1 to
communicate with the local hosts. Meanwhile, Vigor router will communicate with other
network devices through a public IP address. When the data flow passing through, the
Network Address Translation (NAT) function of the router will dedicate to translate
public/private addresses, and the packets will be delivered to the correct host PC in the local
area network. Thus, all the host PCs can share a common Internet connection.

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is
required for bridging customer premises equipment (CPE). Point to Point Protocol over
Ethernet (PPPoE) connects a network of hosts via an access device to a remote access
concentrator or aggregation concentrator. This implementation provides users with significant
ease of use. Meanwhile it provides access control, billing, and type of service according to
user requirement.
When a router begins to connect to your ISP, a serial of discovery process will occur to ask for
a connection. Then a session will be created. Your user ID and password is authenticated via
PAP or CHAP with RADIUS authentication system. And your IP address, DNS server, and
other related information will usually be assigned by your ISP.
