analog telephone to make phone calls over the Internet.
The NVG2053 also supports 3G, which allows you to insert a 3G wireless adapter
in the USB port and use the 3G WAN connection as your WAN or a backup to
enhance network reliability.
You can enable NAT and use Quality of Service (QoS) to efficiently manage traffic
on your network by giving priority to certain types of traffic and/or to particular
computers.
1.2 Applications
Your can create the following networks using the NVG2053:
• LAN. You can connect network devices via the Ethernet ports of the NVG2053
so that they can communicate with each other and access the Internet.

2.6 How to Route Traffic to Another Network
Using Static Route
In order to extend your Intranet and control traffic flow directions, you may
connect a router (R) to the NVG2053’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.
In the following figure, router R is connected to the NVG2053’ 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 NVG2053’s WAN default gateway by default. In this case, B
will never receive the traffic.
N1

2.8 How to Use QoS to Prioritize LAN Traffic
In this example, your Internet connection has an upstream transmission speed of
50 Mbps. You want to configure a QoS class to assign the high priority queue (6)
to VoIP traffic from the phone port(s), so that voice traffic will not get delayed
when there is network congestion. Traffic from the boss’s IP address
(192.168.1.101 for example) is mapped to queue 5. Traffic that does not match
these two classes are assigned priority queue based on the DSCP value in the
packets.

works with existing access control systems (for instance, RADIUS).
One of the benefits of PPPoE is the ability to let end users acce ss 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 specific users.
NVG2053 User’s Guide

Chapter 3 Connection Wizard
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/
carrier, as it requires no specific configuration of the broadband modem at the
subscriber's site.
By implementing PPPoE directly on the NVG2053 (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NVG2053 does that part of the task. Furthermore, with NAT, all of the
LAN's computers will have Internet access.

individual clients to obtain TCP/IP configuration at start-up from a server. You can
configure the NVG2053 as a DHCP server or disable it. When configured as a
server, the NVG2053 provides the TCP/IP configuration for the clients. If DHCP
service is disabled, you must have another DHCP server on that network, or else
the computer must be manually configured.

7.1 Overview
This chapter discusses the NVG2053’s Broadband screens. Use these screens to
configure your NVG2053 for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another
network or the Internet. It connects your private networks such as a LAN (Local
Area Network) and other networks, so that a computer in one location can
communicate with computers in other locations.

Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower
layer protocol. To set up a WAN connection to the Internet, you need to use the
same encapsulation method used by your ISP (Internet Service Provider). If your
ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet), they
should also provide a username and password (and service name) for user
authentication.
WAN IP Address
The WAN IP address is an IP address for the NVG2053, which makes it accessible
from an outside network. It is used by the NVG2053 to communicate with other
devices in other networks. It can be static (fixed) or dynamically assigned by the
ISP each time the NVG2053 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) and a gateway IP address.
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 important because without it, you must
know the IP address of a computer before you can access it.
The NVG2053 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
sheet, 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
NVG2053’s WAN IP address), set the DNS server fields to get the DNS server
address from the ISP.

7.3.2 PPPoE Encapsulation
The NVG2053 supports PPPoE (Point -to-Point Protocol over Ethernet). PPPoE is an
IETF standard (RFC 2516) specifying how a personal computer (PC) inter acts with
a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is
for a dial-up connection using PPPoE.
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 servic e selection. This enables the service
provider to easily create and offer new IP services for individuals.
Operationally, PPP oE save s significant ef fort 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 NVG2053 (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NVG2053 does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.

7.4 Technical Reference
The following section contains additional technical information about the NVG2053
features described in this chapter.
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 devices 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 netw ork resources of another on the same LAN,
thus a user will not see the printers and hard disks of another user in the same
building.
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. Wit h VLAN, all
broadcasts are confined to a specific broadcast domain.

NVG2053 User’s Guide
Chapter 7 Broadband
Introduction to IEEE 802.1Q Tagged VLAN
A tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify 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 frame is four bytes longer than an untagged frame and
contains two bytes of TPID (Tag Protocol Identi f ier), residing within the type/
length field of the Ethernet 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 pr iority frame, meaning that
only the priority level is significant and the default VID of the ingress port is given
as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify
priority frames and value 4095 (FFF) is reserved, so the maximum possible VLAN
configurations are 4,094.

Multicast
IP packets are transmitted in either one of two ways - Unicas t ( 1 sen der - 1
recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers
IP packets to a group 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 host s must join t he 224.0.0.1 group in order
to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers
group.

This chapter discusses how to configure the wireless network settings in your
NVG2053.
The following figure provides an example of a wireless network.
Figure 32 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network,
devices A and B are called wireless clients. The wireless clients use the access
point (AP) to interact with other devices (such as the printer) or with the Internet.
Your NVG2053 is the AP.

See Section 8.10 on page 111 and Appendix C on page 275 for advanced technical
information on wireless networks.
8.1.1 What You Can Do in this Chapter
•Use the General screen (Section 8.3 on page 97) to enable the Wireless LAN,
enter the SSID and select the wireless security mode.
•Use the MAC Filter screen (Section 8.4 on page 104) to allow or deny wireless
clients based on their MAC addresses from connecting to the NVG2053.
•Use the Advanced screen (Section 8.5 on page 105) to allow wireless advanced
features, such as intra-BSS networking and set the RTS/CTS Threshold.
•Use the QoS screen (Section 8.6 on page 107) to have the NVG2053
automatically set priority levels to services, such as e-mail, VoIP, chat, and so
on.
•The WPS screen and the WPS Station screen let you use WiFi Protected Setup
(WPS) to quickly set up a wireless network with strong security, without having
to configure security settings manually.
Use the WPS screen (Section 8.7 on page 107) to enable or disable WPS,
generate a security PIN (Personal Identification Number) and see information
about the NVG2053’s WPS status.
Use the WPS Station (Section 8.8 on page 109) screen to add a wireless client
by pressing a button or using a PIN.
•Use the Scheduling screen (Section 8.9 on page 110) to set the time s your
wireless LAN is turned on and off.
8.2 What You Need to Know
Every wireless network must follow these basic guidelines.
• Every wireless client in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentity.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific
channel, or frequency, to send and receive information.
• Every wireless client in the same wireless network must use securit y compatible
with the AP.
Security stops unauthorized devices from using the wireless net work. It can also
protect the information that is sent in the wireless network.

Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie
radios send and receive information over the airwaves, wireless networking
NVG2053 User’s Guide
Chapter 8 Wireless LAN
devices exchange information with one another. A wireless networking device is
just 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.
Wireless Network Construction
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can
connect with numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and
wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or
more wireless clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless
clients connect to one another in order to exchange information.
Network Names
Each network must have a name, referred to as the SSID - “Service Set
IDentifier”. The “service set” is the network, so the “service set identifier” is the
network’s name. This helps you identify your wireless network when wireless
networks’ coverage areas overlap and you have a variety of networks to choose
from.
Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed,
civilian use. For the purposes of wireless networking, t hese bands are divided into
numerous channels. This allows a variety of networks to exist in the same place
without interfering with one another. When you create a network, you must select
a channel to use.
Since the available unlicensed spectrum varies from one country to another, the
number of available channels also varies.
NVG2053 User’s Guide
95
Chapter 8 Wireless LAN
Wireless Security
By their nature, radio communications are simple to intercept. For wireless data
networks, this means that anyone within range of a wireless network without
security can not only read the data passing over the airwaves, but also join the
network. Once an unauthorized person has access to the network she/he can
either steal information or introduce malware (malicious software) intended to
compromise the network. For these reasons, a variety of security systems have
been developed to ensure that only authorized people can use a wireless data
network, or understand the data carried on it.
These security standards do two things. First, they authenticate. This means that
only people presenting the right credentials (often a username and password, or a
“key” phrase) can access the network. Second, they encrypt. This means that the
information sent over the air is encoded. Only people with the code key can
understand the information, and only people who have been authenticated are
given the code key.
These security standards vary in effectiveness. Some can be broken, such as the
old Wired Equivalent Protocol (WEP). Using WEP is better than using no security at
all, but it will not keep a determined attacker out. Other security standards are
secure in themselves but can be broken if a user does not use them properly. For
example, the WPA-PSK security standard is perfectly secure if you use a long key
which is difficult for an attacker’s softw are to gues s - f or example, a twenty-letter
long string of apparently random numbers and letters - but it is not very secure if
you use a short key which is very easy to guess.
Because of the damage that can be done by a malicious attacker, it’s not just
people who have sensitive information on their network who should use security.
Everybody who uses any wireless network should ensure that effective security is
in place.
A good way to come up with effective security keys , passwords and so on is to use
obscure information that you personally will easily remember, and to enter it in a
way that appears random and does not include real words. For example, if your
mother owns a 1970 Dodge Challenger and her favorite movie is Vanishing Point
(which you know was made in 1971) you could use “70dodchal71vanpoi” as your
security key.
Signal Problems
Because wireless networks are radio networks, their signals are subject to
limitations of distance, interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with
interference occur when other radio waves interrupt the data signal. Interference
may come from other radio transmissions, such as military or air traffic control
96
NVG2053 User’s Guide
communications, or from machines that are coincidental emitters such as electric
motors or microwaves. Problems with absorption occur when physical objects
(such as thick walls) are between the two radios, muffling the signal.
