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.
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 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.
To acquire a public IP address from your ISP for Vigor router as a customer premises
equipment, there are three common protocols: Point to Point Protocol over Ethernet
(PPPoE), PPPoA and MPoA. Multi-PVC is provided for more advanced setup of the
above.
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.

Below shows the menu items for Internet Access.
33..11..22 PPPPPPooEE//PPPPPPooAA
PPPoA, included in RFC1483, can be operated in either Logical Link Control-Subnetwork
(LLC) Access Protocol or VC-Mux mode. As a CPE device, Vigor router encapsulates the
PPP session based for transport across the ADSL loop and your ISP’s Digital Subscriber
Line Access Multiplexer (SDLAM).

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.

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.
You can group local hosts by physical ports and create up to 4 virtual LANs. To manage the
communication between different groups, please set up rules in Virtual LAN (VLAN)

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

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.
DHCP Server IP Address for Relay Agent - Set the IP address of

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,
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 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.
There are two common scenarios of LAN settings that stated in Chapter 4. For the

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.
36
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.

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

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’s 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
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

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

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.
As the popularity of all kinds of instant messenger application arises, communication cannot
become much easier. Nevertheless, while some industry may leverage this as a great tool to
connect with their customers, some industry may take reserve attitude in order to reduce
employee misusage during office hour or prevent unknown security leak. It is similar
situation for corporation towards peer-to-peer applications since file-sharing can be
convenient but insecure at the same time. To address these needs, we provide IM and P2P
blocking functionality.
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
CCoonntteenntt FFiilltteerriinngg
9. Smurf attack
10. SYN fragment
11. ICMP fragment
12. Tear drop attack
13. Fraggle attack
14. Ping of Death attack
15. TCP/UDP port scan
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.
44
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.

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

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

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.
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 Land
Check the box to enforce the Vigor router to defense the Land
attacks. The Land attack combines the SYN attack technology with

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,
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

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:
zClassification: Identifying low-latency or crucial applications and marking them for
high-priority service level enforcement throughout the network.
zScheduling: 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
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.
Vigor2800 Series User’s Guide
61
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.
Enable the QoS Control The factory default for this setting is checked.
Direction Define which traffic the QoS Control settings apply to.
IN- apply to incoming traffic only.
OUT-apply to outgoing traffic only.
BOTH- apply to both incoming and outgoing traffic.
Index The group index number of QoS Control settings. There are
total 4 groups.
Class Name Define the name for the group index.
Reserved Bandwidth Ratio It is reserved for the group index in the form of ratio of
reserved bandwidth to upstream speed and reserved
bandwidth to downstream speed.
Setup There are two-level of settings:
Basic - setup Reserved Bandwidth Ratio according to the
traffic service type. We provide a list of common service
types.

on the source address, destination address, DiffServ
CodePoint, and service type.

Remote Authentication Dial-In User Service (RADIUS) is a security authentication
client/server protocol that supports authentication, authorization and accounting, which is
widely used by Internet service providers. It is the most common method of authenticating
and authorizing dial-up and tunneled network users.
The built-in RADIUS client feature enables the router to assist the remote dial-in user or a
wireless station and the RADIUS server in performing mutual authentication. It enables
centralized remote access authentication for network management.

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 router is “NAT Traversal”. This enables
applications inside the firewall to automatically open the ports that they need to pass through
a router. It is more reliable than requiring a router to work out by itself which ports need to
be opened. Further, the user does not have to manually set up port mappings or a DMZ.
UPnP is available on Windows XP and the router provides the associated support for MSN
Messenger to allow full use of the voice, video and messaging features.
Enable UPNP Service Accordingly, you can enable either the Connection Control
Service or Connection Status Service.
After setting Enable UPNP Service setting, an icon of IP Broadband Connection on
Router on Windows XP/Network Connections will appear. The connection status and
control status will be able to be activated. The NAT Traversal of UPnP enables the
multimedia features of your applications to operate. This has to manually set up port
mappings or use other similar methods. The screenshots below show examples of this
facility.
The UPnP facility on the router enables UPnP aware applications such as MSN Messenger to
discover what are behind a NAT router. The application will also learn the external IP
address and configure port mappings on the router. Subsequently, such a facility forwards
packets from the external ports of the router to the internal ports used by the application.

Vigor2800 Series User’s Guide
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.
¾Some 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.
¾Non-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.

A Virtual Private Network (VPN) is the extension of a private network that encompasses
links across shared or public networks like the Internet. In short, by VPN technology, you
can send data between two computers across a shared or public network in a manner that
emulates the properties of a point-to-point private link.
Below shows the menu items for VPN and Remote Access.
Note: This feature can be applied for ISDN remote dial-in or ISDN LAN-to-LAN
connection in i series models.
Enable the necessary VPN service as you need. If you intend to run a VPN server inside your
LAN, you should disable the VPN service of Vigor Router to allow VPN tunnel pass through,
as well as the appropriate NAT settings, such as DMZ or open port.
The Vigor router will not accept the ISDN dial-in connection if the box of Enable ISDN Dial-in is not checked.

Dial-In PPP
Authentication PAP Only
Select this option to force the router to authenticate dial-in
users with the PAP protocol.
PAP or CHAP
Dial-In PPP Encryption
(MPPE Optional MPPE
Selecting this option means the router will attempt to
authenticate dial-in users with the CHAP protocol first. If the
dial-in user does not support this protocol, it will fall back to
use the PAP protocol for authentication.
This option represents that the MPPE encryption method will
be optionally employed in the router for the remote dial-in
user. If the remote dial-in user does not support the MPPE
encryption algorithm, the router will transmit “no MPPE
encrypted packets”. Otherwise, the MPPE encryption scheme
will be used to encrypt the data.
Require MPPE (40/128bits) - Selecting this option will force
the router to encrypt packets by using the MPPE encryption
algorithm. In addition, the remote dial-in user will use 40-bit
to perform encryption prior to using 128-bit for encryption.
In other words, if 128-bit MPPE encryption method is not
available, then 40-bit encryption scheme will be applied to
encrypt the data.
Maximum MPPE - This option indicates that the router will
use the MPPE encryption scheme with maximum bits
(128-bit) to encrypt the data.
76
Mutual Authentication
(PAP)
The Mutual Authentication function is mainly used to
communicate with other routers or clients who need
bi-directional authentication in order to provide stronger
security, for example, Cisco routers. So you should enable
this function when your peer router requires mutual
authentication. You should further specify the User Name
and Password of the mutual authentication peer.
Start IP AddressEnter a start IP address for the dial-in PPP connection. You
should choose an IP address from the local private network.
For example, if the local private network is
192.168.1.0/255.255.255.0, you could choose 192.168.1.200
as the Start IP Address. But, you have to notice that the first

In IPSec General Setup, there are two major parts of configuration.
There are two phases of IPSec.
¾Phase 1: negotiation of IKE parameters including encryption, hash, Diffie-Hellman
parameter values, and lifetime to protect the following IKE exchange, authentication of
both peers using either a Pre-Shared Key or Digital Signature (x.509). The peer that
starts the negotiation proposes all its policies to the remote peer and then remote peer
tries to find a highest-priority match with its policies. Eventually to set up a secure
tunnel for IKE Phase 2.
¾Phase 2: negotiation IPSec security methods including Authentication Header (AH) or
Encapsulating Security Payload (ESP) for the following IKE exchange and mutual
examination of the secure tunnel establishment.
There are two encapsulation methods used in IPSec, Transport and Tunnel. The Transport
mode will add the AH/ESP payload and use original IP header to encapsulate the data
payload only. It can just apply to local packet, e.g., L2TP over IPSec. The Tunnel mode will
not only add the AH/ESP payload but also use a new IP header (Tunneled IP header) to
encapsulate the whole original IP packet.
Authentication Header (AH) provides data authentication and integrity for IP packets passed
between VPN peers. This is achieved by a keyed one-way hash function to the packet to
create a message digest. This digest will be put in the AH and transmitted along with packets.
On the receiving side, the peer will perform the same one-way hash on the packet and
compare the value with the one in the AH it receives.
Encapsulating Security Payload (ESP) is a security protocol that provides data
confidentiality and protection with optional authentication and replay detection service.
IKE Authentication Method This usually applies to those are remote dial-in user or node
(LAN-to-LAN) which uses dynamic IP address and
IPSec-related VPN connections such as L2TP over IPSec
and IPSec tunnel.
Pre-Shared Key -Currently only support Pre-Shared Key
authentication.

A digital certificate works as an electronic ID, which is issued by a certification authority
(CA). It contains information such as your name, a serial number, expiration dates etc., and
the digital signature of the certificate-issuing authority so that a recipient can verify that the
certificate is real. Here Vigor router support digital certificates conforming to standard
X.509.
Any entity wants to utilize digital certificates should first request a certificate issued by a CA
server. It should also retrieve certificates of other trusted CA servers so it can authenticate
the peer with certificates issued by those trusted CA servers.
Here you can manage generate and manage the local digital certificates, and set trusted CA
certificates. Remember to adjust the time of Vigor router before using the certificate so that
you can get the correct valid period of certificate.

Voice over IP network (VoIP) enables you to use your broadband Internet connection to
make toll quality voice calls over the Internet.
There are many different call signaling protocols, methods by which VoIP devices can talk
to each other. The most popular protocols are SIP, MGCP, Megaco and H.323. These
protocols are not all compatible with each other (except via a soft-switch server).
The Vigor V models support the SIP protocol as this is an ideal and convenient deployment
for the ITSP (Internet Telephony Service Provider) and softphone and is widely supported.
SIP is an end-to-end, signaling protocol that establishes user presence and mobility in VoIP
structure. Every one who wants to talk using his/her SIP Uniform Resource Identifier, “SIP
Address”. The standard format of SIP URI is
sip: user:password @ host: port
Some fields may be optional in different use. In general, "host” refers to a domain. The
“userinfo” includes the user field, the password field and the @ sign following them. This is
very similar to a URL so some may call it “SIP URL”. SIP supports peer-to-peer direct
calling and also calling via a SIP proxy server (a role similar to the gatekeeper in H.323
networks), while the MGCP protocol uses client-server architecture, the calling scenario
being very similar to the current PSTN network.
After a call is setup, the voice streams transmit via RTP (Real-Time Transport Protocol).
Different codecs (methods to compress and encode the voice) can be embedded into RTP
packets. Vigor V models provide various codecs, including G.711 A/µ-law, G.723, G.726
and G.729 A & B. Each codec uses a different bandwidth and hence provides different levels
of voice quality. The more bandwidth a codec uses the better the voice quality, however the
codec used must be appropriate for your Internet bandwidth.
Usually there will be two types of calling scenario, as illustrated below:
z Calling via SIP Servers
First, the Vigor V models of yours will have to register to a SIP Registrar by sending
registration messages to validate. Then, both parties’ SIP proxies will forward the
sequence of messages to caller to establish the session.
If you both register to the same SIP Registrar, then it will be illustrated as below:
The major benefit of this mode is that you don’t have to memorize your friend’s IP
address, which might change very frequently if it’s dynamic. Instead of that, you will
94
Vigor2800 Series User’s Guide
only have to using dial plan or directly dial your friend’s account name if you are
with the same SIP Registrar. Please refer to the Example 1 and 2 in the Calling Scenario.
z Peer-to-Peer
Before calling, you have to know your friend’s IP Address. The Vigor VoIP Routers
will build connection between each other. Please refer to the Example 3 in the Calling
Scenario.
Our Vigor V models firstly apply efficient codecs designed to make the best use of
available bandwidth, but Vigor V models also equip with automatic QoS assurance.
QoS Assurance assists to assign high priority to voice traffic via Internet. You will
always have the required inbound and outbound bandwidth that is prioritized
exclusively for Voice traffic over Internet but you just get your data a little slower and
it is tolerable for data traffic.
Different directions generate different meanings for on-net and off-net.
yISDN On-Net means a user (A) calls another one (B) through ISDN line, routers and
Internet with the yellow route displayed in the following graphic.
User A connects to S0 extern of switchboard through ISDN line. The switchboard
connects to a router(C) with ISDN cable. The router connects to Internet through
WAN port with ADSL cable. When A calls B, the voice signal will be sent to router (C)
through ISDN interface. Next, the voice signal will be transferred to B through Internet.
Such route is named ISDN On-Net (see yellow route).
yISDN Off-Net means a user (B) calls another one (A) through Internet, router and
ISDN line with the blue route displayed in the following graphic.
Vigor2800 Series User’s Guide

User B connects a router with FXS port and accesses Internet through WAN port of
that router. When B calls A, the voice signal will be sent to a remote router (C) through
Internet. Then, the voice signal will be passed to switchboard (via S0 intern) and
transferred to A through ISDN line (leaving Internet). Such route is named ISDN Off-Net (see blue route).
