4.4 Setting Up a Secure Wireless Network

Thomas wants to set up a wireless network so that he can use his notebook to access the Internet. In this wireless network, the ZyXEL Device 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 ZyXEL Device. Then he can set up a wireless network using WPS (Section 4.4.2 on page 52) or manual configuration (Section 4.4.3 on page 56).
4.4.1 Configuring the Wireless Network Settings
This example uses the following parameters to set up a wireless network.

4.4.2 Using WPS
This section shows you how to set up a wireless network using WPS. It uses the ZyXEL Device 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 methods to set up the wireless client settings:
Push Button Configuration (PBC) - simply press a button. This is the easier of the two methods.
PIN Configuration - configure a Personal Identification Number (PIN) on the ZyXEL Device. A wireless client must also use the same PIN in order to download the wireless network settings from the ZyXEL Device.
Push Button Configuration (PBC)
1 Make sure that your ZyXEL Device 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.

4.7 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 ZyXEL Device’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 ZyXEL Device’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 com puter B (in N2 network), the traffic is sent to the ZyXEL Device’s WAN default gateway by default. In this case, B will never receive the traffic.
N1
A
R
N2
B
62
VSG1435-B101 Series User’s Guide

Now B should be able to receive traffic from A. You may need to additionally configure B’s firewall settings to allow specific traffic to pass through.

4.8 Configuring QoS Queue and Class Setup

This section contains tutorials on how you can configure the QoS screen.
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 e­mail 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 exampl e, y ou want to configure QoS so that e­mail traffic gets the highest priority with at least 5,000 kbps. You can do the following:
• Configure a queue to assign the highest priority queue (1) to e-mail traffic g oing to the WAN interface, so that e-mail traffic would not get dela y ed when there i s 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 computer and map it to queue 7.
64
VSG1435-B101 Series User’s Guide
Chapter 4 Tutorials
Note: QoS is applied to traffic flowing out of the ZyXEL Device.
Traffic that does not match this class is assigned a priority queue based on the internal QoS mapping table on the ZyXEL Device.

Broadband

6.1 Overview

This chapter describes how to configure WAN settings from the Broadband screen. Use this screen to configure your ZyXEL Device 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.
Figure 19 LAN and WAN
LAN
6.1.1 What You Need to Know
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) or PPPoA, they should also provide a username and password (and service name) for user authentication.
WAN
VSG1435-B101 Series User’s Guide

Chapter 6 Broadband
WAN IP Address
The WAN IP address is an IP address for the ZyXEL Device, which makes it accessible from an outside network. It is used by the ZyXEL Device to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the ZyXEL Device 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 add ress if you use the Ethernet encapsulation method).
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 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 one.
IGMP
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. There are three versions of IGMP. IGMP version 2 and 3 are improvements over version 1, but IGMP version 1 is still in wide use.
Finding Out More
See Section 6.3 on page 90 for technical background information on WAN.

Click Add new WAN interface in the Broadband screen or the Edit icon next to an existing WAN interface to configure a WAN connection. The screen differs according to the mode and encapsulation you choose.
6.2.2 PPPoE Encapsulation
The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts 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, PPPoE saves significant effort for both yo u 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 ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

6.3 Technical Reference

This section provides some technical background information about the topics covered in this chapter.
6.3.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports the following methods.
6.3.1.1 PPP over Ethernet
The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts 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, PPPoE saves significant effort for both yo u 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 ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.
6.3.1.2 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The ZyXEL Device 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 Subscriber Line (DSL) Access Multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.
90
VSG1435-B101 Series User’s Guide
6.3.2 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 Multiplexing
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 identifying 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.
Chapter 6 Broadband
6.3.3 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information.
6.3.4 IP Address Assignment
A static IP is a fixed IP that your ISP gives y ou. A dynamic IP is not fix e d; 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.
IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and Gateway IP Address fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the Gateway IP Address field.
VSG1435-B101 Series User’s Guide
91
Chapter 6 Broadband
6.3.5 NAT
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network.
6.3.6 Traffic Shaping
T r affic 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 below SCR until cell rate averages to the SCR again. 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 23 Example of Traffic Shaping
92
VSG1435-B101 Series User’s Guide
6.3.7 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 Bit Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-real time (VBR-nRT) connections.
Chapter 6 Broadband
The VBR-R T (real-time V ariable Bit Rate) type is used with burst y connections that require closely controlled delay and 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 video 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.
6.3.8 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.
VSG1435-B101 Series User’s Guide
93
Chapter 6 Broadband
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.
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 Identifier), residing within the typ e/ 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.
TPID 2 Bytes
User Priority 3 Bits
CFI 1 Bit
VLAN ID 12 Bits

7.1.2 What You Need to Know
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send and receive information over the airwaves, wireless networking 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.

7.2.2 Basic (WEP Encryption)
WEP encryption scrambles the data transmitted bet ween the wireless stations and the access points (AP) to keep network communications privat e. Both the wirele ss 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 ZyXEL Device allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can be enabled at any one time.
In order to configure and enable WEP encryption, click Network Settings > Wireless to display the General screen, then select Basic as the security level.
