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

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.

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.

Network Connection by 3G USB Modem

For 3G mobile communication through Access Point is popular more and more, Vigor2830

adds the function of 3G network connection for such purpose. By connecting 3G USB Modem

to the USB port of Vigor2830, it can support HSDPA/UMTS/EDGE/GPRS/GSM and the

future 3G standard (HSUPA, etc). Vigor2830n with 3G USB Modem allows you to receive 3G

signals at any place such as your car or certain location holding outdoor activity and share the

bandwidth for using by more people. Users can use four LAN ports on the router to access

Internet. Also, they can access Internet via 802.11n wireless function of Vigor2830n, and

enjoy the powerful firewall, bandwidth management, VPN features of Vigor2830n series.

After connecting into the router, 3G USB Modem will be regarded as the third WAN port.

However, the original WAN1 and WAN2 still can be used and Load-Balance can be done in

the router. Besides, 3G USB Modem in WAN3 also can be used as backup device. Therefore,

when WAN1 and WAN2 are not available, the router will use 3.5G for supporting

automatically. The supported 3G USB Modem will be listed on Draytek web site. Please visit

www.draytek.com for more detailed information.

3.1.2 General Setup

This section will introduce some general settings of Internet and explain the connection modes

for WAN1, WAN2 and WAN3 in details.

This router supports multiple-WAN function. It allows users to access Internet and combine

the bandwidth of the multiple WANs to speed up the transmission through the network. Each

WAN port can connect to different ISPs, Even if the ISPs use different technology to provide

telecommunication service (such as DSL, Cable modem, etc.). If any connection problem

occurred on one of the ISP connections, all the traffic will be guided and switched to the

normal communication port for proper operation. Please configure WAN1, WAN2 and WAN3

settings.

This webpage allows you to set general setup for WAN1, WAN2 and WAN3 respectively.

Load Balance Mode

This option is available for multiple-WAN for getting enough

bandwidth for each WAN port. If you know the practical
