Vigor2820 series is an ADSL and broadband router with WAN interface. It provides
policy-based load-balance, fail-over and BOD (Bandwidth on Demand), also it integrates IP
layer QoS, NAT session/bandwidth management to help users control works well with large
bandwidth.
By adopting hardware-based VPN platform and hardware encryption of AES/DES/3DS, the
router increases the performance of VPN greatly, and offers several protocols (such as
IPSec/PPTP/L2TP) with up to 32 VPN tunnels.
The object-based design used in SPI (Stateful Packet Inspection) firewall allows users to set
firewall policy with ease. CSM (Content Security Management) provides users control and
management in IM (Instant Messenger) and P2P (Peer to Peer) more efficiency than before.
By the way, DoS/DDoS prevention and URL/Web content filter strengthen the security
outside and control inside.
Vigor2820 “S” series models support two ISDN ports. Phone S0 port is dedicated for ISDN
phone and ISDN/Phone S0 port is configurable for ISDN line and phone if required. It can
support multiple SIP registrars with high flexible configuration and call handling options.
Object-based firewall is flexible and allows your network be safe. In addition, through VoIP
function, the communication fee for you and remote people can be reduced.
Before you use the Vigor router, please get acquainted with the LED indicators and
connectors first.
The displays of LED indicators and connectors for the routers are different slightly. The
following sections will introduce them respectively. If the model of router you have does not
support ISDN and/or VoIP function, simply ignore the relational description.

For the hardware connection, we take “n” model as an example.
Caution: Each of the Phone ports can be connected to an analog phone only. Do not
connect the phone ports to the telephone wall jack. Such connection might damage
your router.
Such information is provided for Vigor2820 S models (e.g., Vigor2820VS).
Phone S0 is always fixed to connect ISDN phone. However, ISDN /Phone S0 is configurable
as NT or TE mode. When the user configures ISDN /Phone S0 as NT mode in VoIP>> Phone Settings, the orange LED will light on to indicate ISDN-NT is selected. And by
using ISDN phone adapters (coming from the router package), the user can connect several
phones to Vigor2820VS for communication. Refer to the following figure for reference.
Yet, if the user configures ISDN / Phone S0 as TE Mode in VoIP>> Phone Settings, the

supports the DSL WAN interface for Internet access.
22..22..11 PPPPPPooEE//PPPPPPooAA
PPPoE stands for Point-to-Point Protocol over Ethernet. It relies on two widely accepted
standards: PPP and Ethernet. It connects users through an Ethernet to the Internet with a
common broadband medium, such as a single DSL line, wireless device or cable modem. All
the users over the Ethernet can share a common connection.
PPPoE is used for most of DSL modem users. All local users can share one PPPoE
connection for accessing the Internet. Your service provider will provide you information
about user name, password, and authentication mode.

After finished basic configuration of the router, you can access Internet with ease. For the
people who want to adjust more setting for suiting his/her request, please refer to this chapter
for getting detailed information about the advanced configuration of this router. As for other
examples of application, please refer to chapter 4.
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
WAN group and click the Internet Access link.
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:
Weebb
W
Coonnffiigguurraattiioonn
C
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
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.
For 3G mobile communication through Access Point is popular more and more, Vigor2820
adds the function of 3G network connection for such purpose. By connecting 3G USB
Modem to the USB port of Vigor2820, it can support HSDPA/UMTS/EDGE/GPRS/GSM
and the future 3G standard (HSUPA, etc). Vigor2820 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
Vigor2820n, and enjoy the powerful firewall, bandwidth management, VPN, VoIP features
of Vigor2820 series.
After connecting into the router, 3G USB Modem will be regarded as the second WAN port.
However, the original Ethernet WAN1 still can be used and Load-Balance can be done in the
router. Besides, 3G USB Modem in WAN2 also can be used as backup device. Therefore,
when WAN1 is 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.

This section will introduce some general settings of Internet and explain the connection
modes for WAN1 and WAN2 in details.
This router supports dual WAN function. It allows users to access Internet and combine the
bandwidth of the dual WAN 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 and WAN2

33..22 LLAANN
Local Area Network (LAN) is a group of subnets regulated and ruled by router. The design
of network structure is related to what type of public IP addresses coming from your ISP.
33..22..11 BBaassiiccss ooff LLAANN
The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the router will talk to other public hosts on the Internet by using
public IP address and talking to local hosts by using its private IP address. What NAT does is
to translate the packets from public IP address to private IP address to forward the right
packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that
assigns private IP address to each local host. See the following diagram for a briefly
understanding.
In some special case, you may have a public IP subnet from your ISP such as
220.135.240.0/24. This means that you can set up a public subnet or call second subnet that
each host is equipped with a public IP address. As a part of the public subnet, the Vigor
router will serve for IP routing to help hosts in the public subnet to communicate with other
public hosts or servers outside. Therefore, the router should be set as the gateway for public
hosts.
Vigor router will exchange routing information with neighboring routers using the RIP to
accomplish IP routing. This allows users to change the information of the router such as IP
address and the routers will automatically inform for each other.
WWhhaatt iiss SSttaattiicc RRoouuttee
When you have several subnets in your LAN, sometimes a more effective and quicker way
for connection is the Static routes function rather than other method. You may simply set
rules to forward data from one specified subnet to another specified subnet without the
presence of RIP.

DHCP Server
Configuration
DHCP stands for Dynamic Host Configuration Protocol. The
router by factory default acts a DHCP server for your network so
it automatically dispatch related IP settings to any local user
configured as a DHCP client. It is highly recommended that you
leave the router enabled as a DHCP server if you do not have a
DHCP server for your network.
If you want to use another DHCP server in the network other than
the Vigor Router’s, you can let Relay Agent help you to redirect the
DHCP request to the specified location.
Enable Server - Let the router assign IP address to every host in
the LAN.
Disable Server – Let you manually assign IP address to every host
in the LAN.
Relay Agent – (1

DHCP server is located the relay agent should redirect the DHCP
request to.
Start IP Address - Enter a value of the IP address pool for the
DHCP server to start with when issuing IP addresses. If the 1st IP
address of your router is 192.168.1.1, the starting IP address must
be 192.168.1.2 or greater, but smaller than 192.168.1.254.
IP Pool Counts - Enter the maximum number of PCs that you
want the DHCP server to assign IP addresses to. The default is 50
and the maximum is 253.
Gateway IP Address - Enter a value of the gateway IP address for
the DHCP server. The value is usually as same as the 1st IP address
of the router, which means the router is the default gateway.

automatically apply default DNS Server IP address: 194.109.6.66
to this field.
Secondary IP Address - You can specify secondary DNS server IP
address here because your ISP often provides you more than one
DNS Server. If your ISP does not provide it, the router will

Note: There are two reasons that we have to apply RIP Protocol Control on 1st
Subnet. The first is that the LAN interface can exchange RIP packets with the
neighboring routers via the 1st subnet (192.168.1.0/24). The second is that those
hosts on the internal private subnets (ex. 192.168.10.0/24) can access the Internet
via the router, and continuously exchange of IP routing information with different
subnets.

Usually, the router serves as an NAT (Network Address Translation) router. NAT is a
mechanism that one or more private IP addresses can be mapped into a single public one.
Public IP address is usually assigned by your ISP, for which you may get charged. Private IP
addresses are recognized only among internal hosts.
When the outgoing packets destined to some public server on the Internet reach the NAT
router, the router will change its source address into the public IP address of the router, select
the available public port, and then forward it. At the same time, the router shall list an entry
in a table to memorize this address/port-mapping relationship. When the public server
response, the incoming traffic, of course, is destined to the router’s public IP address and the
router will do the inversion based on its table. Therefore, the internal host can communicate
with external host smoothly.
The benefit of the NAT includes:
zSave cost on applying public IP address and apply efficient usage of IP address.
NAT allows the internal IP addresses of local hosts to be translated into one public IP
address, thus you can have only one IP address on behalf of the entire internal hosts.
zEnhance security of the internal network by obscuring the IP address. There are
many attacks aiming victims based on the IP address. Since the attacker cannot be
aware of any private IP addresses, the NAT function can protect the internal network.
On NAT page, you will see the private IP address defined in RFC-1918. Usually we use
the 192.168.1.0/24 subnet for the router. As stated before, the NAT facility can map one
or more IP addresses and/or service ports into different specified services. In other words,
the NAT function can be achieved by using port mapping methods.
Below shows the menu items for NAT.

Port Redirection is usually set up for server related service inside the local network (LAN),
such as web servers, FTP servers, E-mail servers etc. Most of the case, you need a public IP
address for each server and this public IP address/domain name are recognized by all users.
Since the server is actually located inside the LAN, the network well protected by NAT of
the router, and identified by its private IP address/port, the goal of Port Redirection function

Vigor2820 Series User’s Guide
is to forward all access request with public IP address from external users to the mapping
private IP address/port of the server.
The port redirection can only apply to incoming traffic.
To use this function, please go to NAT page and choose Port Redirection web page. The

Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc.
Since the common port numbers of these services (servers) are all the same, you may need to
reset the router in order to avoid confliction.
For example, the built-in web configurator in the router is with default port 80, which may
conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you need
to change the router’s http port toany one other than the default port 80 to avoid
Vigor2820 Series User’s Guide
conflict, such as 8080. This can be set in the System Maintenance >>Management Setup.
You then will access the admin screen of by suffixing the IP address with 8080, e.g.,

As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on
particular ports to the specific private IP address/port of host in the LAN. However, other IP
protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor
router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a
single host in the LAN. Regular web surfing and other such Internet activities from other
clients will continue to work without inappropriate interruption. DMZ Host allows a defined

While the broadband users demand more bandwidth for multimedia, interactive applications,
or distance learning, security has been always the most concerned. The firewall of the Vigor
router helps to protect your local network against attack from unauthorized outsiders. It also
restricts users in the local network from accessing the Internet. Furthermore, it can filter out
specific packets that trigger the router to build an unwanted outgoing connection.
FFiirreewwaallll FFaacciilliittiieess
The users on the LAN are provided with secured protection by the following firewall
facilities:
z User-configurable IP filter (Call Filter/ Data Filter).
z Stateful Packet Inspection (SPI): tracks packets and denies unsolicited incoming data
z Selectable Denial of Service (DoS) /Distributed DoS (DDoS) attacks protection
IIPP FFiilltteerrss
Depending on whether there is an existing Internet connection, or in other words “the WAN
link status is up or down”, the IP filter architecture categorizes traffic into two: Call Filter
and Data Filter.
zCall Filter - When there is no existing Internet connection, Call Filter is applied to all
traffic, all of which should be outgoing. It will check packets according to the filter
rules. If legal, the packet will pass. Then the router shall “initiate a call” to build the
Internet connection and send the packet to Internet.
zData Filter - When there is an existing Internet connection, Data Filter is applied to
incoming and outgoing traffic. It will check packets according to the filter rules. If legal,
the packet will pass the router.
The following illustrations are flow charts explaining how router will treat incoming traffic
and outgoing traffic respectively.
Stateful inspection is a firewall architecture that works at the network layer. Unlike legacy
static packet filtering, which examines a packet based on the information in its header,
stateful inspection builds up a state machine to track each connection traversing all interfaces
of the firewall and makes sure they are valid. The stateful firewall of Vigor router not just
examine the header information also monitor the state of the connection.
The DoS Defense functionality helps you to detect and mitigate the DoS attack. The attacks
are usually categorized into two types, the flooding-type attacks and the vulnerability attacks.
The flooding-type attacks will attempt to exhaust all your system's resource while the
vulnerability attacks will try to paralyze the system by offending the vulnerabilities of the
protocol or operation system.
The DoS Defense function enables the Vigor router to inspect every incoming packet based
on the attack signature database. Any malicious packet that might duplicate itself to paralyze
the host in the secure LAN will be strictly blocked and a Syslog message will be sent as
warning, if you set up Syslog server.
Also the Vigor router monitors the traffic. Any abnormal traffic flow violating the pre-defined
parameter, such as the number of thresholds, is identified as an attack and the Vigor router
will activate its defense mechanism to mitigate in a real-time manner.
The below shows the attack types that DoS/DDoS defense function can detect:
1. SYN flood attack
2. UDP flood attack
3. ICMP flood attack
4. Port Scan attack
5. IP options
6. Land attack
7. Smurf attack
8. Trace route

As a sub-functionality of IP Filter/Firewall, there are 15 types of detect/ defense function in
the DoS Defense setup. The DoS Defense functionality is disabled for default.
Click Firewall and click DoS Defense to open the setup page.
Enable Dos Defense Check the box to activate the DoS Defense Functionality.
Enable SYN flood
defense
Check the box to activate the SYN flood defense function. Once
detecting the Threshold of the TCP SYN packets from the Internet
has exceeded the defined value, the Vigor router will start to
randomly discard the subsequent TCP SYN packets for a period
defined in Timeout. The goal for this is prevent the TCP SYN
packets’ attempt to exhaust the limited-resource of Vigor router.
By default, the threshold and timeout values are set to 50 packets
per second and 10 seconds, respectively.
Enable UDP flood
defense
Check the box to activate the UDP flood defense function. Once
detecting the Threshold of the UDP packets from the Internet has
exceeded the defined value, the Vigor router will start to randomly
discard the subsequent UDP packets for a period defined in
Timeout. The default setting for threshold and timeout are 150
packets per second and 10 seconds, respectively.
Enable ICMP flood
defense
Check the box to activate the ICMP flood defense function. Similar
to the UDP flood defense function, once if the Threshold of ICMP
packets from Internet has exceeded the defined value, the router
will discard the ICMP echo requests coming from the Internet. The
default setting for threshold and timeout are 50 packets per second
and 10 seconds, respectively.
Enable PortScan

85
detecting this malicious exploration behavior by monitoring the
port-scanning Threshold rate, the Vigor router will send out a
warning. By default, the Vigor router sets the threshold as 150
packets per second.
Block IP optionsCheck the box to activate the Block IP options function. The Vigor
router will ignore any IP packets with IP option field in the
datagram header. The reason for limitation is IP option appears to
be a vulnerability of the security for the LAN because it will carry
significant information, such as security, TCC (closed user group)
parameters, a series of Internet addresses, routing messages...etc.
An eavesdropper outside might learn the details of your private
networks.
Block Land Check the box to enforce the Vigor router to defense the Land
attacks. The Land attack combines the SYN attack technology with
IP spoofing. A Land attack occurs when an attacker sends spoofed
SYN packets with the identical source and destination addresses, as
well as the port number to victims.
Block SmurfCheck the box to activate the Block Smurf function. The Vigor
router will ignore any broadcasting ICMP echo request.
Block trace routerCheck the box to enforce the Vigor router not to forward any trace
route packets.
Block SYN fragmentCheck the box to activate the Block SYN fragment function. The
Vigor router will drop any packets having SYN flag and more
fragment bit set.
Block Fraggle AttackCheck the box to activate the Block fraggle Attack function. Any
broadcast UDP packets received from the Internet is blocked.
Activating the DoS/DDoS defense functionality might block some
legal packets. For example, when you activate the fraggle attack
defense, all broadcast UDP packets coming from the Internet are
blocked. Therefore, the RIP packets from the Internet might be
dropped.
Block TCP flag scanCheck the box to activate the Block TCP flag scan function. Any
TCP packet with anomaly flag setting is dropped. Those scanning
activities include no flag scan, FIN without ACK scan, SYN FINscan, Xmas scan and full Xmas scan.
Block Tear DropCheck the box to activate the Block Tear Drop function. Many
machines may crash when receiving ICMP datagrams (packets) that
exceed the maximum length. To avoid this type of attack, the Vigor
router is designed to be capable of discarding any fragmented ICMP
packets with a length greater than 1024 octets.
86
Block Ping of DeathCheck the box to activate the Block Ping of Death function. This
attack involves the perpetrator sending overlapping packets to the
target hosts so that those target hosts will hang once they
re-construct the packets. The Vigor routers will block any packets
realizing this attacking activity.
Block ICMP Fragment Check the box to activate the Block ICMP fragment function. Any
ICMP packets with more fragment bit set are dropped.
Block Unknown
Protocol
Check the box to activate the Block Unknown Protocol function.
Individual IP packet has a protocol field in the datagram header to
Vigor2820 Series User’s Guide
indicate the protocol type running over the upper layer. However,
the protocol types greater than 100 are reserved and undefined at
this time. Therefore, the router should have ability to detect and
reject this kind of packets.
Warning MessagesWe provide Syslog function for user to retrieve message from Vigor
router. The user, as a Syslog Server, shall receive the report sending
from Vigor router which is a Syslog Client.
All the warning messages related to DoS Defense will be sent to
user and user can review it through Syslog daemon. Look for the
keyword DoS in the message, followed by a name to indicate what
kind of attacks is detected.
