Vigor122, an ADSL2/2+ modem, integrates IP layer QoS, NAT session/bandwidth management
to help users control works well with large bandwidth.

DrayTek Vigor122 supports PPPoE/PPPoA relay (PPPoA to PPPoE bridging) and the firewall,
router or PC all can log into the Internet (your ISP) directly, having complete control over the
ADSL connection.

Therefore it is possible to connect a PPPoE client to the Vigor122 (firewall, Ethernet-WAN
router, Apple Airpor or PC) even if the connection to your ISP is still PPPoA (unlike
other-brand modems which only offers PPPoE native bridging). This unique feature is very
convenient for PPPoA -based ISPs.

With the Vigor122 bridge/modem, you can have a true single public IP address (or multiple, if
you subscribe them) rightly through to your router/or firewall, which also has full control of
the ISP connection.

Accordingly, it is ideal for home users and client running multi WAN routers like the Vigor3900,
Vigor2960, Vigor3220, Vigor2952, Vigor2925, Vigor2912 series and even connecting to the
second WAN port on the Vigor2860 series.

The Vigor122 supports TR-069 and it works with most TR-069-based central management
system. VigorACS centralized management system can also facilitate ISP's deployment of
installing Vigor122 and provide professional remote management for ISP.

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

As the modem 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 modem 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 modem 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.

MPoA is a specification that enables ATM services to be integrated with existing LANs, which
use either Ethernet, token-ring or TCP/IP protocols. The goal of MPoA is to allow different
LANs to send packets to each other via an ATM backbone.

For static IP mode, you usually receive a fixed public IP address or a public subnet, namely
multiple public IP addresses from your DSL or Cable ISP service providers. In most case s, a
Cable service provider will offer a fixed public IP, while a DSL service prov ider will offer a
public subnet. If you have a public subnet, you could assign an IP address or many IP address

IIII--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.

The most generic function of Vigor router is NAT. It creates a private subnet of your own. As
mentioned previously, the modem will talk to other public hosts on the Internet by using
public IP address and talking to local hosts by using its private I P ad dress. 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 serve r that assigns
private IP address to each local host. See the following diagram for a briefly understanding.

WWhhaatt iiss RRoouuttiinngg IInnffoorrmmaattiioonn PPrroottooccooll ((RRIIPP))

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 modem such as IP
address and the modems 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.

This page provides you the general settings for LAN.
Click LAN to open the LAN settings page and choose General Setup.

Available settings are explained as follows:

Item Description
Network Configuration For NAT Usage,

IP Address - Type in private IP address for connecting to a

local private network (Default: 192.168.1.1).
Subnet Mask - Type in an address code that determines the

size of the network. (Default: 255.255.255.0/ 24)

DHCP Server
Configuration

DHCP stands for Dynamic Host Configuration Protocol. The
modem by factory default acts a DHCP server for your
network so it automatically dispatches related IP settings to
any local user configured as a DHCP client. It is highly
recommended that you leave the modem 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 modem assign IP address to every
host in the LAN.

Disable Server – Let you manually assign IP address to every
host in the LAN.

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 I P
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

Vigor122 User’s Guide

2

the 1st IP address of the modem, which means the modem is
the default gateway.

DNS Server IP Address DNS stands for Domain Name System. Every Internet host

must have a unique IP address, also they may have a
human-friendly, easy to remember name such as
www.yahoo.com. The DNS server converts the user-friendly
name into its equivalent IP address.

Primary IP Address -You must specify a DNS server IP address
here because your ISP should provide you with usually more
than one DNS Server. If your ISP does not provide it, the
modem will 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 provide s you more
than one DNS Server. If your ISP does not provide it, the
modem will automatically apply default secondary DNS
Server IP address: 194.98.0.1 to this field.

The default DNS Server IP address can be found via Online
Status:

If both the Primary IP and Secondary IP Address fields are left
empty, the modem will assign its own IP address to local
users as a DNS proxy server and maintain a DNS cache.

If the IP address of a domain name is already in the DNS
cache, the modem will resolve the domain name
immediately. Otherwise, the modem forwards the DNS query
packet to the external DNS server by establishing a WAN (e.g.
DSL/Cable) connection.

IIII--33 NNAATT

Usually, the modem 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 modem will change its source address into the public IP address of the modem,
select the available public port, and then forward it. At the same time, the modem 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 modem’s pu blic IP address
and the modem will do the inversion based on its table. Therefore, the internal host can
communicate with external host smoothly.

The benefit of the NAT includes:
 Save 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.

 Enhance 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.

Info

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 modem. 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.

Since the server is actually located inside the LAN, the network well protected by NAT of the
modem, and identified by its private IP address/port, the goal of Port Redirection fun ction i s
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 Port

Note that the modem 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 modem in order to avoid confliction.

For example, the built-in web user interface in the modem 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 modem’s http port to any one other than the default port 80 to avoid
conflict, such as 8080. This can be set in the System Maintenanc e >>Management Setup. You
then will access the admin screen of by suffixing the IP address with 8080, e.g.,
http://192.168.1.1:8080 instead of port 80.

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 client s will
continue to work without inappropriate interruption. DMZ Host allows a defined internal user
to be totally exposed to the Internet, which usually helps some special applications such as

The ISP often provides you with a dynamic IP address when you connect to the Internet via
your ISP. It means that the public IP address assigned to your router changes each time you
access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic
WAN IP address. It allows the modem to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the modem is online, you will be able to use the
registered domain name to access the modem or internal virtual servers from the Internet. It
is particularly helpful if you host a web server, FTP server, or other server behind the modem.

Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the DDNS
service providers. The modem provides up to three accounts from three different DDNS
service providers. Basically, Vigor routers are compatible with the DDNS services supplied by
most popular DDNS service providers such as www.dyndns.org, www.no-ip.com,
www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com. You should visit
their websites to register your own domain name for the modem.

The Vigor router has a built-in clock which can update itself manually or automatically by
means of Network Time Protocols (NTP). As a result, you can n ot only schedule the modem to
dialup to the Internet at a specified time, but also restrict Internet access to certain hours so
that users can connect to the Internet only during certain hours, say, business hours. The
schedule is also applicable to other functions.

UUPPnnPP

The UPnP (Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers,
the major feature of UPnP on the modem is “NAT Traversal”. This enables app lication s inside
the firewall to automatically open the ports that they need to pass through a router.

IIGGMMPP

IGMP is the abbreviation of Internet Group Management Protocol. It is a communication
protocol which is mainly used for managing the membership of Internet Protocol multicast
groups. For invoking IGMP Snooping function, you have to check the Enable IGMP Proxy box
first for activating the IGMP proxy function.

IIII--44--33 UUPPnnPP

The UPnP (Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers,
the major feature of UPnP on the modem is “NAT Traversal”. This enables app lication s inside
the firewall to automatically open the ports that they need to pass through a router.

Info

UPnP is required for some applications such as PPS, Skype, eMule...and etc.
If you are not familiar with UPnP, it is suggested to turn off this function for
security.

Available settings are explained as follows:

Item Description

The reminder as regards concern about Firewall and UPnP

Can't work with Firewall Software

Enabling firewall applications on your PC may cause the UPnP function not working
properly. This is because these applications will block the accessing ability of some network
ports.

Security Considerations

Activating the UPnP function on your network may incur some security threats. You should
consider carefully these risks before activating the UPnP function.

 Some Microsoft operating systems have found out the UPnP weaknesses and hence
you need to ensure that you have applied the latest service packs and patches.

 Non-privileged users can control some router functions, including removing and
adding port mappings.

The UPnP function dynamically adds port mappings on behalf of some UPnP-aware
applications. When the applications terminate abnormally, these mappings may not be
removed.

Here is an example (based on IPv4) of setting Static Route in Main Router so that user A and B
locating in different subnet can talk to each other via the modem. Assuming the Internet
access has been configured and the modem works properly:

 use the Main Router to surf the Internet.
 create a private subnet 192.168.10.0 using an internal Router A (192.168.1.2)
 create a public subnet 211.100.88.0 via an internal Router B (192.168.1.3).
 have set Main Router 192.168.1.1 as the default gateway for the modem A 192.168.1.2.

Before setting Static Route, user A cannot talk to user B for Router A can only forward
recognized packets to its default gateway Main Router.

1. Go to LAN page and click General Setup, select 1st Subnet as the RIP Protocol Contr ol.
Then click the OK button.

Info

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
modem, and continuously exchange of IP routing informat ion with
different subnets.

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 modem to build an unwanted outgoing connection.

FFiirreewwaallll FFaacciilliittiieess

The users on the LAN are provided with secured protection by the following firewall facilities:

 User-configurable IP filter (Call Filter/ Data Filter).
 Stateful Packet Inspection (SPI): tracks packets and denies unsolicited incoming data
 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.

 Call 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 modem shall “initiate a call” to build the
Internet connection and send the packet to Internet.

 Data 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 modem.

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 only examines the header information also monitors the state of the connection.

DDeenniiaall ooff SSeerrvviiccee ((DDooSS)) DDeeffeennssee

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 mess age 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

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.

Available settings are explained as follows:

Item Description
Enable Dos Defense Check the box to activate the DoS Defense Functionality.
Select All Click this button to select all the items listed below.
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. That

means, when 50 packets per second received, they will be

regarded as “attack event” and the session will be paused

for 10 seconds.

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. That

means, when 150 packets per second received, they will be

regarded as “attack event” and the session will be paused

for 10 seconds.

Vigor122 User’s Guide

58

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 modem 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. That

means, when 50 packets per second received, they will be

regarded as “attack event” and the session will be paused

for 10 seconds.

Enable PortScan detection Port Scan attacks the Vigor router by sending lots of packets

to many ports in an attempt to find ignorant services would

respond. Check the box to activate the Port Scan

detection. Whenever 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. That means, when 150 packets per

second received, they will be regarded as “attack event”.
Block IP options Check 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 Smurf Check the box to activate the Block Smurf function. The

Vigor router will ignore any broadcasting ICMP echo

request.
Block trace route Check the box to enforce the Vigor router not to forward

any trace route packets.
Block SYN fragment Check 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 Attack Check 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 scan Check 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.

Vigor122 User’s Guide

59

Block Tear Drop Check 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.
Block Ping of Death Check 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 Undefined Protocol Check the box to activate the Block Undefined Protocol

function. Individual IP packet has a protocol field in the

datagram header to 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 Messages We 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.
