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/4G USB Modem
For 3G/4G mobile communication through Access Point is popular more and more,
Vigor2860 adds the function of 3G/4G network connection for such purpose. By connecting
3G/4G USB Modem to the USB port of Vigor2860, it can support
LTE/HSDPA/UMTS/EDGE/GPRS/GSM and the future 3G/4G standard (HSUPA, etc).
Vigor2860n with 3G/4G USB Modem allows you to receive 3G/4G 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 LAN ports on the router to access Internet. Also, they can access
Internet via 802.11(a/b/g/n/ac) wireless standard, and enjoy the powerful firewall, bandwidth
management, and VPN features of Vigor2860n series.
After connecting into the router, 3G/4G USB Modem will be regarded as the WAN3/WAN4
port. However, the original WAN1 and WAN2 still can be used and Load-Balance can be
done in the router. Besides, 3G/4G USB Modem in WAN3/WAN4 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/4G 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/WAN4 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, WAN3
and WAN4 settings.
This webpage allows you to set general setup for WAN1, WAN2, WAN3 and WAN4
respectively. In default, WAN2 is disabled. If you want to enable it, simply click the WAN2
link and select
Yes
in the field of
