1.3 Good Habits for Managing the VMG
Do the following things regularly to make the VMG more secure and to manage the VMG more
effectively.
• Change the password. Use a password that’s not easy to guess and that con sists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be usef ul if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the VMG to its factory default settings. If you backed
up an earlier configuration file, you wou ld not have to totally re-configure the VMG. You could
simply restore your last configuration.

1.4 Applications for the VMG
1.4.1 Internet Access
1.4.1.1 DSL
Here are some example uses for w hich the VMG is well suited.
Computers can connect to the VMG’s LAN ports (or wirelessly).
You can also configure IP filtering on the VMG for secure Internet access. When the IP filter is on, all
incoming traffic from the Inter net to your network is blocked by default unless it is initiated from
your network. This mean s that probes from the outside to your network ar e not allowed, but you
can safely browse the Internet and download files.
Your VMG provides shared Internet access by connecting the DSL port to the DSL or MODEM jack
on a splitter or your telephone jack. You can have multiple WAN services over one ADSL or VDSL.
The VMG cannot work in ADSL and VDSL mode at the same time.
Note: The ADSL and VDSL lines share the same WAN (layer-2) interfaces that you
configure in the VMG. Refer to Section 6.2 on page 63 for the Network Setting >
Broadband screen.

1.4.1.2 Ethernet WAN
If you prefer not to use a DSL line and you have another broadband modem or router (such as
ADSL) available, you can convert LAN port number four as a WAN port using the Network Setting
> Broadband > Etherne t WAN screen and then connect the LAN port to the broadband modem
or router. This way, you can access the Internet via an Ethernet connection and still u se the QoS,
Firewall and parental control functions on the VMG.

1.4.2 VMG’s USB Support
The USB port of the VMG is used for 3G WAN backup, file-sharing and media server.
3G WAN Backup
Connect a 3G/LTE USB dongle with an active SIM card to the USB port. This adds a second WAN
interface and a llows the VMG to wirele s sly access the Inte r net via a 3G/LTE network. The 3G/LTE
WAN connection is the f ailover or a backup in case the DSL or Ethernet WAN connection fails.
To set up a 3G/LTE connection, click Network Setting > Broadband > 3G Backup.
To update the supported 3G/LTE USB dongle lis t, download the late st WWAN package from the
ZyXEL website and upload it to the VMG using the Maintenance > Firmware Upgrade screen.
See the product page on ZyXEL’s website for the list of 3G/LTE US B don gles that are compatible.

Thomas wants to set up a wireless network so that he can use his notebook to access the Internet.
In this wireless network, the VMG serves as an access point (AP), and the notebook is the wireless
client. The wireless client can access the Internet through the AP.
Thomas has to configure the wireless network settings on the VMG. T hen he c an set up a wireless
network using WPS (Section 4.3.2 on page 36) or manual configuration (Section 4.3.3 on page 39).

Thomas can now use the WPS feature to establish a wireless connection between his notebook and
the VMG (see Section 4.3.2 on page 36). He can also use the notebook’s wireless client to search
for the VMG (see Section 4.3.3 on page 39).
4.3.2 Using WPS
This section shows you how to set up a wireless network using WPS. It uses the VMG as the AP and
ZyXEL NWD210N as the wireless client which connects to the notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter
or PCMCIA card).
There are two WPS meth ods to set up the wireless client settings:
• Push Button Configuration (P BC ) - simply press a button. This is the easier of the two
methods.
• PIN Configuration - configur e a Personal Identification Number (PIN) on the VMG. A wireless
client must also use the same PIN in order to download the wireless network settings from the
VMG.
Push Button Configuration (PBC)
1 Make sure that your VMG is turned on and your notebook is within the cover range of the wireless
signal.
2 Make sure that you have installed the wireless client driver and utility in your notebook.
3 In the wireless client utility, go to the WPS setting page. Enable WPS and press the WPS button
(Start or WPS button).
4 Push and hold the WPS button located on the VMG’s front pane l for more than 5 seconds.
Alternatively, you may log into VMG’s web configurator and go to the Network Setting >
Wireless > WPS screen. Enable the WPS function for method 1 and click Apply. Then click the
WPS button.

Note: Your VMG has a WPS button located on the side of the device as well as a WPS
button in its configuration utility. Both buttons have exactly the same function: you
can use one or the other.
Note: It doesn’t matter which button is pressed first. You must press the second button
within two minutes of pressing the first one.
The VMG sends the proper configuration settings to the wireless client. This may take up to two
minutes. The wireless client is then able to communicate with the VMG securely.
The following figure shows you an example of how to set up a wireless network and its security by
pressing a button on both VMG and wireless client.

4.5 Configuring Static Route for Routing to Another
Network
In order to extend your Intranet and control traffic flowing directions, you may connect a router to
the VMG’s LAN. The router may be used to separate two department networks. This tutorial shows
how to configure a static routing rule for two network routings.
VMG1312-B10D User’s Guide

Chapter 4 Tutorials
A
In the following figure, router R is connected to t he VMG ’s LAN. R connects to two networks, N1
(192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1
network) to computer B (in N2 network), the traffic is sent to the VMG’s WAN default gateway by
default. In this case, B will never receive the traffic.
N1
A
R
N2
B
You need to specify a static routing rule on the VMG to specify R as the router in charge of
forwarding traffic to N2. In this case, the VMG routes traffic from A to R and then R routes the
traffic to B.
N1
A
R

4.6 Configuring QoS Queue and Class Setup
This section contains tutorials on how you can configure the QoS screen.
VMG1312-B10D User’s Guide

Chapter 4 Tutorials
Let’s say you are a team leader of a small sales branch office. You want to prioritize e-mail traffic
because your task includes sending urgent updates to clients at least twice every hour. You also
upload data files (such as logs and e-mail archives) to the FTP server throughout the day. Your
colleagues use the Internet for research, as well as chat applications for communicating with other
branch offices.
In the following figure, your Internet connection has an upstream transmission bandwidth of
10,000 kbps. For this ex amp le, you want to configure QoS so that e-mail traffic gets the highest
priority with at lea st 5,000 kbps. You can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic going to the WAN
interface, so th a t e -mail traffic would not get delayed when there is network congestion.
• Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for
example) of your com puter and map it to queue 7.
Note: QoS is applied to traffic flowing out of the VMG.
Traffic that does not match th is class is assigned a priority queue based on the internal QoS
mapping table on the VMG.

4.7 Access the VMG Using DDNS
If you connect your VMG to the Internet and it uses a dynamic WAN IP address, it is inconvenient
for you to manage the device from the Internet. The VMG’s WAN IP address changes dynamically.
Dynamic DNS (DDNS) allows you to access the VMG using a domain name.
w.x.y.z
To use this feature, you have to apply for DDNS service at, for example, www.dyndns.org.
http://zyxelrouter.dyndns.org

WAN IP Address
The WAN IP address is an IP address for the VMG, which makes it accessible from an outside
network. It is used by the V MG to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the VMG tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es).
ATM
Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data
transfer. ATM uses fixed-size packets of informati on called cells. With ATM, a high QoS (Quality of
Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit
(VC) between Finding Out More
PTM
Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM,
packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed
VMG1312-B10D User’s Guide
60
Chapter 6 Broadband
to provide a low-overhead, transparent way of transporting packets over DSL links, as an
alternative to ATM.
IPv6 Introduction
IPv6 (Intern et Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
addresses. The VMG can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and
supports IPv6 rapid deployment (6RD).
38
IP
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So
2001:0db8:1a2b:0015:0000:0000:1a2f:0000
2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double
colon can only appear once in an IPv6 address. So
2001:0db8:0000:0000:1a2f:0000:0000:0015
2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15
or 2001:db8:0:0:1a2f::15.
can be written as
can be written as
IPv6 Prefix and Prefix Length
Similar to an IP v4 subnet mask, IPv6 uses an address prefix to represent the network address. An
IPv6 prefix length specifies how many most significant bits (s tart from the left) in the address
compose the network address. The prefix len g th is written as “/x” where x is a number. For
example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.
IPv6 Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits , which are divided
into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each
character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal
characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
IPv6 Rapid Deployment
Use IPv6 Rapid Deployment (6r d) when the local network uses IPv6 and the ISP has an IPv4
network. When the VMG has an IPv4 WAN address and you set IPv4/IPv6 Mode to IPv4 Only,
you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The VMG generates a global IPv6 prefix from its IPv4 WAN a ddr es s and tunnels IPv6 traffic to the
ISP’s Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The loca l

When the VMG has an IPv6 WAN address and you set IPv4/IPv6 Mode to IPv6 Only, you can
enable Dual Stack Lite to use IPv4 computers and services.
The VMG tunnels IPv4 packets inside IPv6 enc apsulation packets to the ISP’s Address Family
Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also
use IPv6 services. The VMG uses it’s configured IPv6 WAN IP to route IPv 6 traffic to the IPv6

In addition to the VMG’s built-in PPPoE client, you can enable PPPoE pass through to allow up
to ten hosts on the LAN to use PPPoE client software on their computers to connect to the
ISP via the VMG. Each host can have a separate account and a public WAN IP address.
PPPoE pass through is an alternative to NAT for application where NAT is not appropriate.
Disable PPPoE pass through if you do not need to allow hosts on the LAN to use PPPoE client
software on their computers to connect to the ISP.
A static IP address is a fixed IP that your ISP gives you. A dynamic IP address is not fixed;
the ISP assigns you a different one each time you connect to the Internet. Select this if you

you select IPoE or PPPoE in the Select DSL Link Type field.
• VC/MUX: In VC multiplexing, each protocol is carried on a single ATM virtual circuit
(VC). To transport multiple protocols, the VMG needs separate VCs. There is a binding
between a VC and the type of the network protocol carried on the VC. This reduces
payload overhead since there is no need to carry protocol information in each Protocol

ITU G.992.1 (better known as G.dmt) is an ITU standard for ADSL using discrete multitone
modulation. G.dmt full-rate ADSL expands the usable bandwidth of existing copper
telephone lines, delivering high-speed data communications at rates up to 8 Mbit/s
downstream and 1.3 Mbit/s upstream.
ITU G.992.2 (better known as G.lite) is an ITU standard for ADSL using discrete multitone
modulation. G.lite does not strictly require the use of DSL filters, but like all variants of
ADSL generally functions better with splitters.
ANSI T1.413 is a technical standard that defines the requirements for the single asymmetric
digital subscriber line (ADSL) for the interface between the
the customer installation in terms of their interaction and electrical characteristics.
It optionally extends the capability of basic ADSL in data rates to 12 Mbit/s downstream
and, depending on Annex version, up to 3.5 Mbit/s upstream (with a mandatory capability
of ADSL2 transceivers of 8 Mbit/s downstream and 800 kbit/s upstream).
Annex L is an optional specification in the ITU-T ADSL2 recommendation G.992.3 titled
Specific requirements for a Reach Extended ADSL2 (READSL2) system operating in the
frequency band above POTS, therefore it is often referred to as Reach Extended ADSL2 or
READSL2.The main difference between this specification and commonly deployed Annex A is
the maximum distance that can be used. The power of the lower frequencies used for
transmitting data is boosted up to increase the reach of this signal up to 7 kilometers
(23,000 ft).
ADSL2+ extends the capability of basic ADSL by doubling the number of downstream
channels. The data rates can be as high as 24 Mbit/s downstream and up to 1.4 Mbit/s
upstream depending on the distance from the DSLAM to the customer's premises.
Annex M is an optional specification in ITU-T recommendations G.992.3 (ADSL2) and
G.992.5 (ADSL2+), also referred to as ADSL2 M and ADSL2+ M. This specification extends
the capability of commonly deployed Annex A by more than doubling the number of
upstream bits. The data rates can be as high as 12 or 24 Mbit/s downstream and 3 Mbit/s
upstream depending on the distance from the DSLAM to the customer's premises.

6.7 Technical R ef er ence
The following section contains additional technical information about the VMG features described in
this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The VMG can work in bridge mode
or routing mode. When the VMG is in routing mode, it supports the following methods.
VMG1312-B10D User’s Guide
81
Chapter 6 Broadband
IP over Ethernet
IP over Ethernet (IPoE) is an alternative to PPPoE. IP packets are being delivered across an
Ethernet network, without using PPP encapsulation. They are routed between the Ethernet interface
and the WAN interface and then formatted so that they can be understood in a bridged
environment. For instance, it encapsulates routed Ethernet frames into bridged Ethernet cells.
PPP over ATM (PPPoA)
PPPoA stands for Poin t to Point Protocol over ATM Adaptation L a yer 5 (AAL5). A PPPoA connection
functions like a dial-up Internet connection. The VMG encapsulates the PPP session based on
RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service
Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information
on PPPoA. Refer to R F C 1661 for more information on PPP.
PPP over Ethernet (PPPoE)
Point-to-Point Protocol over Ethernet (PPPoE) provides access control and billing functionality in a
manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how
a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.)
connection.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example RADIUS).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a
function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for individuals.
Operationally, PPPoE saves sign ificant effort for both you and the ISP or carrier, as it requires no
specific configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the VMG (rather than individual computers), the computers on
the LAN do not need PPPoE software installed, since the VMG does that part of the task.
Furthermore, with NAT, all of the LANs’ computers will have access.
RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5
(AAL5). The first method allows multiplexing of multiple pr otocols over a single ATM virtual circuit
(LLC-based multiplexing) and the second method assumes that each protocol is c a r ried over a
separate ATM virtual circuit (VC-based multiplexing). Please refer to RFC 1483 for more detailed
information.
Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to
use the multiplexing method required by your ISP.
VC-based Multiplex ing
VMG1312-B10D User’s Guide
82
Chapter 6 Broadband
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for
example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where
dynamic creation of large numbers of ATM VCs is fast and economical.
LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identif ying information being contained
in each packet header. Despite the extra bandwidth and processing overhead, this method may be
advantageous if it is not practical to have a separate VC for each carried protocol, for example, if
charging heavily depends on the number of simultaneous VCs.
Traffic Shaping
Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate
and fluctuations of data transmission over an ATM network. This agreement helps eliminate
congestion, which is important for transmission of real time data such as audio and video
connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may
be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a
maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed
because it is dependent on the line speed.
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the
maximum average rate at which cells can be sent over the virtual connection . SCR may not be
greater than the PCR.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS
is reached, cell rates fall b e low SCR until cell rate averages to the SCR aga in. At this time, more
cells (up to the MBS) can be sent at the PCR again.
If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that
correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 32 Example of Traffic Shaping
VMG1312-B10D User’s Guide

Chapter 6 Broadband
ATM Traffic Classes
These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0
Specification.
Constant Bit Rate (CBR)
Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being
sent. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections
that continuously require a specific amount of bandwidth. A PCR is specified and if traffic exceeds
this rate, cells may be dropped. Examples of connections that need CBR would be high-resolution
video and voice.
Variable Bit Rate (VBR)
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use
the Variable B it Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-re a l time
(VBR-nRT) connections.
The VBR-RT (real-time Variable Bit Rate) type is used with bursty connections that require c losely
controlled delay a nd delay variation. It also provides a fixed amount of bandwidth (a PCR is
specified) but is only available when data is being sent. An example of an VBR-RT connection would
be video conferencing. Video conferencing requires real-time data transfers and the bandwidth
requirement varies in proportion to the vid eo image's changing dynamics.
The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do not
require closely controlled delay and delay variation. It is commonly used for "bursty" traffic typical
on LANs. PCR and MBS define the burst levels, SCR defines the minimum level. An example of an
VBR-nRT connection would be non-time sensitive data file transfers.
Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR doesn't
guarantee any bandwidth and only delivers traffic when the network has spare bandwidth. An
example application is background file transfer.
IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a
different one each time. The Single User Account feature can be enabled or disabled if you have
either a dynamic or static IP. However the encapsulation method assigned influences your choices
for IP address and default gateway.
Introduction to VLANs
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devic es that are not in the same
group(s); the traffic must first go through a router.
In Multi-Tenant Unit (MTU) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
resources of another on the same LAN, thus a user will not see the printers and hard disks of
another user in the sam e build ing.
VMG1312-B10D User’s Guide
84
Chapter 6 Broadband
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast packets
go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
Introduction to IEEE 802.1Q Tagged VLAN
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identif y the VLAN membership
of a frame across bridges - they are not confined to the switch on which they were created. The
VLANs can be created statically by hand or dynamically through GVRP. The VLAN ID associates a
frame with a specific VLAN and provides the information that switches need to process the frame
across the network. A tagged f rame is four bytes longer than an untagged frame and contains two
bytes of TPID (Tag Pr otocol Identifier), residing within the type/length field of the E thernet frame)
and two bytes of TCI (Tag Control Information), starts after the source address field of the Ethernet
frame).
The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If
a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as
it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum
number of 4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A
frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority
level is significant and the defau lt VID of the ingress port is given as the VID of the frame. Of the
4096 p
so the maximum possible VLAN conf ig urations are 4,094.
ossible VIDs, a VID of 0 is used to identify priority frames and value 4095 (FFF) is reserved,
TPID
2 Bytes
Multicast
IP packets are transmitted in either one of two ways - Unicast (1 sender - 1 recipient) or Broadcast
(1 sender - everybody on the network). Multicast delivers IP packets to a gr oup of hosts on the
network - not everybody and not just 1.
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership
in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to
read more detailed information about interoperability between IGMP version 2 and version 1, please
see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be
in the range 224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is not assigned to any group
and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is
assigned to the permanent group of all IP hosts (including gateways). All hosts must join the
224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast
routers group.
At start up, the VMG queries all directly connected networks to gather group membership. After
that, the VMG periodically updates this information.
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely

Chapter 6 Broadband
important because without it, you must know the IP address of a computer before you can access
it.
The VMG can get the DNS server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sh eet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the VMG’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.
IPv6 Addressing
The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This
is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000.
IPv6 addresses can be abbreviated in two ways:
• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can
be written as 2001:db8:1a2b:15:0:0:1a2f:0.
• Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can
only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be
written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015,
2001:db8::1a2f:0:0:15 or
2001:db8:0:0:1a2f::15.
IPv6 Prefix and Prefix Length
Similar to an IP v4 subnet mask, IPv6 uses an address prefix to represent the network address. An
IPv6 prefix length specifies how many most significant bits (s tart from the left) i n the address
compose the network address. The prefix length is written as “/x” where x is a number. For
example,
2001:db8:1a2b:15::1a2f:0/32
means that the first 32 bits (2001:db8) is the subnet prefix.

Wireless Basics
“Wireless” is ess e ntially radio comm unication. In the same way th a t walkie-talkie radios send and
receive information over the airwowaves, wireless networking devices exc hange information w ith
one another. A wireless networking device is j ust like a radio that lets your computer exchange
information with radios attached to other computers. Like walkie-talkies, most wireless networking
devices operate at radio frequency bands that are open to the public and do not require a license to
use. However, wireless networking is different from that of most traditional radio communications in
that there a number of wireless networking standards available with different methods of data
encryption.

7.2.2 Basic (WEP Encryption)
WEP encryption scrambles the data transmitted between the wireless stations and the access points
(AP) to keep network communications private. Both the wireless stations and the access points
must use the same WEP key.
Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using
widely-available software. It is strongly recommended that you use a more
effective security mechanism. Use the strongest security mechanism that all the
wireless devices in your network support. For example, use WPA-PSK or WPA2-PSK
if all your wireless devices support it, or use WPA or WPA2 if your wireless devices
support it and you have a RADIUS server. If your wireless devices support nothing
stronger than WEP, use the highest encryption level available.
Your VMG allows you to configure up to four 64-bit or 128-bit WEP keys but on ly one key can be
enabled at any one time.
In order to configure and enable WEP encryption, click Network Setting > Wireless to display the

If you chose 64-bit WEP, then enter any 5 ASCII characters or 10 hexadecimal characters
("0-9", "A-F").
If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal characters
("0-9", "A-F").
You must configure at least one password, only one password can be activated at any one
time.
Select password unmask to display the entered password in plain text. Clear it to hide the
password to avoid shoulder surfing.
This dictates the length of the security key that the network is going to use.
7.2.3 More Secure (WPA(2)-PSK)
The WPA-PSK security mode provides both improved data encryption and user authent i c a t ion over
WEP. Using a Pre-Shared Key (PSK), both the VMG and the connecting client share a common
password in order to validate the connection. This type of encryption, while robust, is not as strong
as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer, more robust version of
the WPA encryption standard. It offers slightly better security, although the use of PSK makes it
less robust than it could be.
Click Network Setting > Wireless to display the General screen. Select More Secure as the
security level.
