2.6 Internet Access Setup
Quick Start Wizard
offers user an easy method to quick setup the connection mode for the
router. Moreover, if you want to adjust more settings for different WAN modes, please go to
Quick Setup
group and click the
Internet Access Setup
link. This section will introduce
some basic concepts of Internet and explain the connection modes in details.
2.6.1 Basics of Internet Protocol (IP) Network
IP means Internet Protocol. Every device in an IP-based Network including routers, print
server, and host PCs, needs an IP address to identify its location on the network. To avoid
address conflicts, IP addresses are publicly registered with the Network Information Centre
(NIC). Having a unique IP address is mandatory for those devices participated in the public
network but not in the private TCP/IP local area networks (LANs), such as host PCs under the
management of a router since they do not need to be accessed by the public. Hence, the NIC
has reserved certain addresses that will never be registered publicly. These are known as
private
IP addresses, and are listed in the following ranges:
From 10.0.0.0 to 10.255.255.255
From 172.16.0.0 to 172.31.255.255
From 192.168.0.0 to 192.168.255.255
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
To acquire a public IP address from your ISP for Vigor router as a customer premises
equipment, there are three common protocols:
Point to Point Protocol over Ethernet
(PPPoE), PPPoA
and
MPoA
.
Multi-PVC
is provided for more advanced setup of the above.
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.
In the
Quick Setup
field, you can configure the router for different connection types, such as
ISDN, PPPoE, PPTP, Dynamic/Static IP or Broadband Access with ISDN dial backup. Note
that the types of ISDN and Broadband Access with ISDN dial backup are available only to
Vigor routers with the ISDN interface (e.g. Vigor2900VGi).
