What are Public IP Address and Private IP Address
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
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.
Get Your Public IP Address from ISP
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.
Below shows the menu items for Internet Access.
4.1.2 PPPoE/PPPoA
PPPoA, included in RFC1483, can be operated in either Logical Link Control-Subnetwork
Access Protocol or VC-Mux mode. As a CPE device, Vigor router encapsulates the PPP
session based for transport across the ADSL loop and your ISP’s Digital Subscriber Line
Access Multiplexer (SDLAM).
To choose PPPoE or PPPoA as the accessing protocol of the internet, please select
PPPoE/PPPoA
from the
Internet Access
menu. The following web page will be shown.
