Vigor2930 is a broadband router with dual-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, hardware encryption of AES/DES/3DS and
hardware key hash of SHA-1/MD5, the router increases the performance of VPN greatly,
and offers several protocols (such as IPSec/PPTP/L2TP) with up to 100 VPN tunnels.
The object-originated 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.
Vigor2930 “S” series models support two ISDN ports. ISDN S0 (1) port is dedicated for
ISDN phone and ISDN S0 (2) 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-oriented 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.

Below shows the names that displayed on front panel of the device and the WEB UI of this
device.
ISDN TE (Terminal Equipment) means an interface for transmitting analog signal through
Internet between Switching and router. Such interface is also named with ISDN S0 extern in
Germany.
ISDN NT (Network Terminator) is a port that used to connect general phone. Such interface
is also named with ISDN S0 intern in Germany.
The ISDN S0 (1) port on Vigor2930 series is fixed to connect phone forever and the LED on
the connecter will light orange always. However ISDN S0 (2) port on this device is
configurable for connecting phone or accessing Internet according to the settings that you
adjust on WEB UI (please refer to VoIP>>Phone Setting for detailed information).
Warning: When the orange LED lights (means ISDN NT mode), the ISDN
port can be used to connect phone only. Wrong ISDN connection might cause
severe damage on your device.

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:

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.

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.

When you have several subnets in your LAN, sometimes a more effective and quicker way

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 nu mber of PCs t hat 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

DHCP Server IP Address for Relay Agent - Set the IP address of
the DHCP server you are going to use so the Relay Agent can help
to forward the DHCP request to the DHCP server.
DNS Server
Configuration
DNS stands for Domain Name System. Every Internet host must
have a unique IP address, also they may have a human-friendly,

Access server (PPPoE, PPTP, L2TP or DHCP server).
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 router 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 provides you more than one
DNS Server. If your ISP does not provide it, the router 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 router will assign its own IP address to local users as a
DNS proxy server and maintain a DNS cache.

z use the Main Router to surf the Internet.
z create a private subnet 192.168.10.0 using an internal Router A (192.168.1.2)
z create a public subnet 211.100.88.0 via an internal Router B (192.168.1.3).
z have set Main Router 192.168.1.1 as the default gateway for the Router A 192.168.1.2.
Before setting Static Route, user A cannot talk to user B for Router A can only forward

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.
2. Click the LAN - Static Route and click on the Index Number 1. Check the Enable

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:
z 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.
48
z 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.
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 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

Private IP Specify the private IP address of the internal host providing the
service. If you choose Range as the port redirection mode, you will
see two boxes on this field. Type a complete IP address in the first
box (as the starting point) and the fourth digits in the second box
(as the end point).
Private Port Specify the private port number of the service offered by the
internal host.
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 to any one other than the default port 80 to avoid
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.,
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 clients 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 Netmeeting or Internet Games etc.

To provide an appropriate cyberspace to users, Vigor router equips with URL Content Filter
not only to limit illegal traffic from/to the inappropriate web sites but also prohibit other web
feature where malicious code may conceal.
Once a user type in or click on an URL with objectionable keywords, URL keyword blocking
facility will decline the HTTP request to that web page thus can limit user’s access to the
website. You may imagine URL Content Filter as a well-trained convenience-store clerk
who won’t sell adult magazines to teenagers. At office, URL Content Filter can also provide
a job-related only environment hence to increase the employee work efficiency. How can
URL Content Filter work better than traditional firewall in the field of filtering? Because it
checks the URL strings or some of HTTP data hiding in the payload of TCP packets while
legacy firewall inspects packets based on the fields of TCP/IP headers only.
On the other hand, Vigor router can prevent user from accidentally downloading malicious
codes from web pages. It’s very common that malicious codes conceal in the executable
objects, such as ActiveX, Java Applet, compressed files, and other executable files. Once
downloading these types of files from websites, you may risk bringing threat to your system.
For example, an ActiveX control object is usually used for providing interactive web feature.
If malicious code hides inside, it may occupy user’s system.
Based on the list of user defined keywords, the URL Content Filter facility in Vigor router
inspects the URL string in every outgoing HTTP request. No matter the URL string is found
full or partial matched with a keyword, the Vigor router will block the associated HTTP
connection.
For example, if you add key words such as “sex”, Vigor router will limit web access to web
sites or web pages such as “www.sex.com”, ”www.backdoor.net/images/sex/p_386.html”.
Or you may simply specify the full or partial URL such as “www.sex.com” or “sex.com”.
Also the Vigor router will discard any request that tries to retrieve the malicious code. Click CSM and click URL Content Filter Profile to open the setup page.

We all know that the content on the Internet just like other types of media may be
inappropriate sometimes. As a responsible parent or employer, you should protect those in
your trust against the hazards. With Web filtering service of the Vigor router, you can protect
your business from common primary threats, such as productivity, legal liability, network and
security threats. For parents, you can protect your children from viewing adult websites or
chat rooms.
Once you have activated your Web Filtering service in Vigor router and chosen the categories
of website you wish to restrict, each URL address requested (e.g.www.bbc.co.uk) will be
checked against our server database, powered by SurfControl. The database covering over 70
languages and 200 countries, over 1 billion Web pages divided into 40 easy-to-understand
categories. This database is updated as frequent as daily by a global team of Internet
researchers. The server will look up the URL and return a category to your router. Your Vigor
router will then decide whether to allow access to this site according to the categories you have
selected. Please note that this action will not introduce any delay in your Web surfing because
each of multiple load balanced database servers can handle millions of requests for
categorization.

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.
The most basic security concept is to set user name and password while you install your
router. The administrator login will prevent unauthorized access to the router configuration
from your router.
If you did not set password during installation; you can go to System Maintenance to set up
your password.

The users on the LAN are provided with secured protection by the following firewall
facilities:
z User-configurable IP filter (Call Filter/ Data Filter).

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.
z 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 router shall “initiate a call” to build the
Internet connection and send the packet to Internet.
z 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 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. TCP Flag scan
5. Trace route
6. IP options
7. Unknown protocol
8. Land attack

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

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.

Check the box to activate the Port Scan detection. Whenever
detecting this malicious exploration behavior by monitoring the
79
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 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 router 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.
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.
80
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
indicate the protocol type running over the upper layer. However,
Vigor2930 Series User’s Guide
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.

Deploying QoS (Quality of Service) management to guarantee that all applications receive
the service levels required and sufficient bandwidth to meet performance expectations is
indeed one important aspect of modern enterprise network.
One reason for QoS is that numerous TCP-based applications tend to continually increase
their transmission rate and consume all available bandwidth, which is called TCP slow start.
If other applications are not protected by QoS, it will detract much from their performance in
the overcrowded network. This is especially essential to those are low tolerant of loss, delay
or jitter (delay variation).
Another reason is due to congestions at network intersections where speeds of
interconnected circuits mismatch or traffic aggregates, packets will queue up and traffic can
be throttled back to a lower speed. If there’s no defined priority to specify which packets
should be discarded (or in another term “dropped”) from an overflowing queue, packets of
sensitive applications mentioned above might be the ones to drop off. How this will affect
application performance?
You can type in four sets of time schedule for your request.
All the schedules can be set previously in Application –
Schedule web page and you can use the number that you
have set in that web page.
There are two components within Primary configuration of QoS deployment:
z Classification: Identifying low-latency or crucial applications and marking them for
high-priority service level enforcement throughout the network.
z Scheduling: Based on classification of service level to assign packets to queues and
associated service types
The basic QoS implementation in Vigor routers is to classify and schedule packets based on
the service type information in the IP header. For instance, to ensure the connection with the
headquarter, a teleworker may enforce an index of QoS Control to reserve bandwidth for
HTTPS connection while using lots of application at the same time.
One more larger-scale implementation of QoS network is to apply DSCP (Differentiated
Service Code Point) and IP Precedence disciplines at Layer 3. Compared with legacy IP
Precedence that uses Type of Service (ToS) field in the IP header to define 8 service classes,
DSCP is a successor creating 64 classes possible with backward IP Precedence compatibility.
In a QoS-enabled network, or Differentiated Service (DiffServ or DS) framework, a DS
domain owner should sign a Service License Agreement (SLA) with other DS domain
Vigor2930 Series User’s Guide
85
owners to define the service level provided toward traffic from different domains. Then each
DS node in these domains will perform the priority treatment. This is called
per-hop-behavior (PHB). The definition of PHB includes Expedited Forwarding (EF),
Assured Forwarding (AF), and Best Effort (BE). AF defines the four classes of delivery (or
forwarding) classes and three levels of drop precedence in each class.
Vigor routers as edge routers of DS domain shall check the marked DSCP value in the IP
header of bypassing traffic, thus to allocate certain amount of resource execute appropriate
policing, classification or scheduling. The core routers in the backbone will do the same
checking before executing treatments in order to ensure service-level consistency throughout
the whole QoS-enabled network.
However, each node may take different attitude toward packets with high priority marking
since it may bind with the business deal of SLA among different DS domain owners. It’s not
easy to achieve deterministic and consistent high-priority QoS traffic throughout the whole
network with merely Vigor router’s effort.
In the Bandwidth Management menu, click Quality of Service to open the web page.
This page displays the QoS settings result of the WAN interface. Click the Setup link to
access into next page for the general setup of WAN (1/2) interface. As to class rule, simply
click the Edit link to access into next for configuration.
You can configure general setup for the WAN interface, edit the Class Rule, and edit the
Service Type for the Class Rule for your request.

When you click Setup, you can configure the bandwidth ratio for QoS of the WAN interface.
There are four queues allowed for QoS control. The first three (Class 1 to Class 3) class rules
can be adjusted for your necessity. Yet, the last one is reserved for the packets which are not
suitable for the user-defined class rules.

Enable the QoS Control The factory default for this setting is checked.
Please also define which traffic the QoS Control settings will
apply to.
IN- apply to incoming traffic only.
OUT-apply to outgoing traffic only.
BOTH- apply to both incoming and outgoing traffic.
Check this box and click OK, then click Setup link again.
You will see the Online Statistics link appearing on this page.
WAN Inbound Bandwidth It allows you to set the connecting rate of data input for WAN.
For example, if your ADSL supports 1M of downstream and
256K upstream, please set 1000kbps for this box. The default
value is 10000kbps.
WAN Outbound Bandwidth It allows you to set the connecting rate of data output for
WAN. For example, if your ADSL supports 1M of
downstream and 256K upstream, please set 256kbps for this
box. The default value is 10000kbps.
Note: The rate of outbound/inbound must be smaller than the real bandwidth to ensure
correct calculation of QoS. It is suggested to set the bandwidth value for inbound/outbound
as 80% - 85% of physical network speed provided by ISP to maximize the QoS
performance.
Reserved Bandwidth Ratio It is reserved for the group index in the form of ratio of

bandwidth to downstream speed.
Check this and set the limited bandwidth ratio on the right
field. This is a protection of TCP application traffic since
UDP application traffic such as streaming video will exhaust
lots of bandwidth.
The difference in bandwidth between download and upload

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 router to update its online WAN IP address mappings on the
specified Dynamic DNS server. Once the router is online, you will be able to use the
registered domain name to access the router or internal virtual servers from the Internet. It is
particularly helpful if you host a web server, FTP server, or other server behind the router.
Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the
DDNS service providers. The router 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 router.
Enable the Function and Add a Dynamic DNS Account
1. Assume you have a registered domain name from the DDNS provider, say
hostname.dyndns.org, and an account with username: test and password: test.
2. In the DDNS setup menu, check Enable Dynamic DNS Setup.
Set to Factory Default Clear all profiles and recover to factory settings.
Enable Dynamic DNS Setup Check this box to enable DDNS function.
Index Click the number below Index to access into the setting
page of DDNS setup to set account(s).
