Getting To Know the ZyXEL
This chapter describes the key features and applications of your device.
1.1 Introducing the ZyXEL Device
The ZyXEL Device is an Integrated Access Device (IAD) that combines an ADSL2+ router with Voice over IP (VoIP) communication capabilities to allow you to use a traditional analog or ISDN telephone to make Internet calls. By integrating DSL and NAT, you are provided with ease of installation and high-speed, shared Internet access. The ZyXEL Device is also a complete security solution with a robust firewall and content filtering.
P-2602HWNLI User’s Guide
CHAPTER 1
Device
At the time of writing, this guide covers the following models.
Table 1 Models Covered
P-2602HWNLI-D3A
P-2602HWNLI-D7A
Please refer to the following description of the product name format.
• In the ZyXEL Device product name, “H” denotes an integrated 4-port switch (hub).
• “W” denotes wireless functionality. There is an embedded mini-PCI module for IEEE
802.11g wireless LAN connectivity.
• “N” denotes the ability to connect an ISDN (Integrated Services Digital Network) telephone to the device.
• “L” denotes the PSTN (Public Switched Telephone Network) line feature.
Note: When the ZyXEL Device does not have power, only the phone connected to the
PHONE 1 port can be used for making calls. Ensure you know which phone
this is, so that in case of emergency you can make outgoing calls.
• “I” denotes the ISDN (Integrated Services Digital Network) line feature.
1
The P-2602HWNLI-D3A works over ISDN (Integrated Services Digital Network).
1. A device that includes both “L” and “I” in the model name can support either a PSTN line or a ISDN line, but not both at the same time.
Chapter 1 Getting To Know the ZyXEL Device 39
Page 40
P-2602HWNLI User’s Guide
The P-2602HWNLI-D7A works over T-ISDN (UR-2).
Note: Only use firmware for your ZyXEL Device’s specific model. Refer to the label on
the bottom of your ZyXEL Device.
The web browser-based Graphical User Interface (GUI) provides easy management.

1.2 Features

The following sections introduce your device’s key features.
Ethernet Ports
The 10/100 Mbps auto-negotiating Ethernet ports allow the device to detect the speed of incoming transmissions and adjust appropriately without manual intervention. Data transfer rates are either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Ethernet port connections can be in half-duplex or full-duplex mode. Full-duplex refers to a device's ability to send and receive simultaneously, while half-duplex indicates that traffic can flow in only one direction at a time. The Ethernet port must use the same speed or duplex mode setting as the peer Ethernet port in order to connect.
The ports are auto-crossover (MDI/MDI-X) meaning they automatically adjust to either crossover or straight-through Ethernet cables.
High Speed Internet Access
The ZyXEL Device is ideal for high-speed Internet browsing and making LAN-to-LAN connections to remote networks. The ZyXEL Device is an ADSL router compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable by the ZyXEL Device for each standard are shown in the following table.
Table 2 ADSL Standards
STANDARD UPSTREAM DATA RATE DOWNSTREAM DATA RATE
ADSL
ADSL2
ADSL2+
832 kbps 8 Mbps
1 Mbps 12 Mbps
1 Mbps 24 Mbps
Note: The standard your ISP uses determines the maximum upstream and
downstream speeds attainable. Actual speeds attained also depend on the distance from your ISP, line quality, your subscribed level of service and other factors.

P-2602HWNLI User’s Guide
PSTN Line
You can connect a PSTN line to your device. You can receive incoming PSTN phone calls even while someone else is making VoIP phone calls. You can dial a (prefix) number to make an outgoing PSTN call. You can still make PSTN phone calls if your device loses power.
Note: When the ZyXEL Device does not have power, only the phone connected to the
PHONE 1 port can be used for making calls. Ensure you know which phone
this is, so that in case of emergency you can make outgoing calls.
ISDN Line
You can connect a ISDN line to your device. You can receive incoming ISDN phone calls even while someone else is making VoIP phone calls. You can dial a (prefix) number to make an outgoing ISDN call.
Zero Configuration Internet Access
Once you connect and turn on the device, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the ZyXEL Device cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.
Any IP
The Any IP feature allows a computer to access the Internet and the ZyXEL Device without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet.
Auto Provisioning
Your VoIP service provider can automatically update your device’s configuration via an auto­provisioning server.
Auto Firmware Upgrade
Your device gives you the option to upgrade to a newer firmware version if it finds one during auto-provisioning. Your VoIP service provider must have an auto-provisioning server and a server set up with firmware in order for this feature to work.
Firewall
Your device has a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.

4-port Switch
A combination of switch and router makes your ZyXEL Device a cost-effective and viable network solution. You can connect up to four computers to the ZyXEL Device without the cost of a hub. Use a hub to add more than four computers to your LAN.
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).
Content Filtering
Content filtering allows you to block access to Internet web sites that contain key words (that you specify) in the URL. You can also schedule when to perform the filtering and give trusted LAN IP addresses unfiltered Internet access.
Media Bandwidth Management
Media Bandwidth Management allows you to specify bandwidth classes based on an application and/or subnet. You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to different bandwidth classes.
REN
A Ringer Equivalence Number (REN) is used to determine the number of devices (like telephones or fax machines) that may be connected to the telephone line. Your device has a REN of three, so it can support three devices per telephone port.
Virtual Private Networks (VPN)
The ZyXEL Device allows companies to establish VPN connections with business partners, as well as with remote and branch offices. VPN uses data encryption and the Internet to provide transparent, secure communications between two or more sites without the expense of leased site-to-site lines. Moreover, using VPN, telecommuters and home workers can access data more easily and safely at home.
The ZyXEL Device VPN is based on the IPSec standard and is fully interoperable with other IPSec-based VPN products.
Dynamic Jitter Buffer
The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic. This helps ensure good voice quality for your conversations.
42 Chapter 1 Getting To Know the ZyXEL Device
Page 43
P-2602HWNLI User’s Guide
Multiple SIP Accounts
You can simultaneously use multiple voice (SIP) accounts and assign them to one or both telephone ports.
Multiple Voice Channels
Your device can simultaneously handle multiple voice channels (telephone calls). Additionally you can answer an incoming phone call on a VoIP account, even while someone else is using the account for a phone call.
Voice Activity Detection/Silence Suppression
Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting when you are not speaking.
Comfort Noise Generation
Your device generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection).
Echo Cancellation
You device supports G.168, an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.
QoS (Quality of Service)
Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. Your device supports Type of Service (ToS) tagging. This allows the device to tag voice frames so they can be prioritized over the network.
SIP ALG
Your device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through NAT for devices behind it (such as a SIP-based VoIP software application on a computer).
Universal Plug and Play (UPnP)
Your device and other UPnP enabled devices can use the standard TCP/IP protocol to dynamically join a network, obtain an IP address and convey their capabilities to each other.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on your device is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual computers.
Chapter 1 Getting To Know the ZyXEL Device 43
Page 44
P-2602HWNLI User’s Guide
Other PPPoE Features
• PPPoE idle time out
• PPPoE dial on demand
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. Your device has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. Your device can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.
Multiple PVC (Permanent Virtual Circuits) Support
Your device supports up to 8 Permanent Virtual Circuits (PVC’s).
IP Alias
IP alias allows you to partition a physical network into logical networks over the same Ethernet interface. Your device supports three logical LAN interfaces via its single physical Ethernet interface with the your device itself as the gateway for each LAN network.
IP Policy Routing (IPPR)
Traditionally, routing is based on the destination address only and the router takes the shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator.
Packet Filters
Your device’s packet filtering function allows added network security and management.
Ease of Installation
Your device is designed for quick, intuitive and easy installation.
Housing
Your device's compact and ventilated housing minimizes space requirements, making it easy to position anywhere in your busy office.

1.3 Applications

Here are some example uses for which the ZyXEL Device is well suited.

1.3.1 Internet Access

Your device is the ideal high-speed Internet access solution. It supports the TCP/IP protocol, which the Internet uses exclusively. It is compatible with all major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a backbone network interface/connection (for example, T1, OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for ADSL. In addition, your device allows wireless clients access to your network resources and the Internet. A typical Internet access application is shown below.
Figure 1 Internet Access Application
1.3.1.1 Internet Single User Account
For a SOHO (Small Office/Home Office) environment, your device offers the Single User Account (SUA) feature that allows multiple users on the LAN (Local Area Network) to access the Internet concurrently for the cost of a single IP address

1.3.2 Making Calls via Internet Telephony Service Provider

In a home or small office environment, you can use your device to make and receive VoIP telephone calls through an Internet Telephony Service Provider (ITSP).
46 Chapter 1 Getting To Know the ZyXEL Device
Page 47
P-2602HWNLI User’s Guide
The following figure shows a basic example of how you would make a VoIP call through an ITSP. You use your analog phone (A in the figure) and your device (B) changes the call into VoIP. Your device then sends your call to the Internet and the ITSP’s SIP server. The VoIP call server forwards calls to PSTN phones (E) through a trunking gateway (D) to the PSTN network. The VoIP call server forwards calls to IP phones (F) through the Internet.
Figure 2 Internet Telephony Service Provider Application

1.3.3 Make Peer-to-peer Calls

You can call directly to someone’s IP address without using a SIP proxy server. Peer-to-peer calls are also called “Point to Point” or “IP-to-IP” calls. You must know the peer’s IP address in order to do this.
The following figure shows a basic example of how you would make a peer-to-peer VoIP call. You use your analog phone (A in the figure) and your device (B) changes the call into VoIP. and sends the call through the Internet to the peer VoIP device (C).
Figure 3 Peer-to-peer Calling

1.3.4 Firewall for Secure Broadband Internet Access

Your device provides protection from attacks by Internet hackers. By default, the firewall blocks all incoming traffic from the WAN. The firewall supports TCP/UDP inspection and DoS (Denial of Services) detection and prevention, as well as real time alerts, reports and logs.

1.4 Splitters and Microfilters

This section describes how to connect ADSL splitters and microfilters. See your Quick Start Guide for details on other hardware connections.
50 Chapter 1 Getting To Know the ZyXEL Device
Page 51

1.4.1 Connecting a POTS Splitter

When you use the Full Rate (G.dmt) ADSL standard, you can use a POTS (Plain Old Telephone Service) splitter to separate the telephone and ADSL signals. This allows simultaneous Internet access and telephone service on the same line. A splitter also eliminates the destructive interference conditions caused by telephone sets.
Install the POTS splitter at the point where the telephone line enters your residence, as shown in the following figure.
Figure 7 Connecting a POTS Splitter
P-2602HWNLI User’s Guide
1 Connect the side labeled “Phone” to your telephone.
2 Connect the side labeled “Modem” or “DSL” to your ZyXEL Device.
3 Connect the side labeled “Line” to the telephone wall jack.

1.4.2 Telephone Microfilters

Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter, for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice transmissions. The use of a telephone microfilter is optional.
1 Locate and disconnect each telephone.
2 Connect a cable from the wall jack to the “wall side” of the microfilter.
3 Connect the “phone side” of the microfilter to your telephone as shown in the following
figure.
4 After you are done, make sure that your telephone works. If your telephone does not
work, disconnect the microfilter and contact either your local telephone company or the provider of the microfilter.

Bandwidth Management Wizard

This chapter shows you how to configure basic bandwidth management using the wizard screens.

5.1 Introduction

Bandwidth management allows you to control the amount of bandwidth going out through the ZyXEL Device’s interfaces and prioritize the distribution of the bandwidth according to service bandwidth requirements. This helps keep one service from using all of the available bandwidth and shutting out other users.

5.2 Predefined Media Bandwidth Management Services

The following is a description of the services that you can select and to which you can apply media bandwidth management using the wizard screens.

This chapter describes how to configure WAN settings.
6.1 WAN Overview
A WAN (Wide Area Network) is an outside connection to another network or the Internet.

6.1.1 Encapsulation

Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports the following methods.
P-2602HWNLI User’s Guide
CHAPTER 6

WAN Setup

6.1.1.1 ENET ENCAP

The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets 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 ATM cells. ENET ENCAP requires that you specify a gateway IP address in the ENET ENCAP Gateway field. You can get this information from your ISP.

6.1.1.2 PPP over Ethernet

PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP. The ZyXEL Device bridges a PPP session over Ethernet (PPP over Ethernet, RFC
2516) from your computer to an ATM PVC (Permanent Virtual Circuit) which connects to ADSL Access Concentrator where the PPP session terminates. One PVC can support any number of PPP sessions from your LAN. For more information on PPPoE, see the appendices.

6.1.1.3 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 access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.
Chapter 6 WAN Setup 87
Page 88
P-2602HWNLI User’s Guide

6.1.1.4 RFC 1483

RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.

6.1.2 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.

6.1.2.1 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.

6.1.2.2 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.

6.1.3 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.

6.1.4 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. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP gateway.

6.1.4.1 IP Assignment with PPPoA or PPPoE Encapsulation

If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway 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 ENET ENCAP Gateway field.
88 Chapter 6 WAN Setup
Page 89

6.1.4.2 IP Assignment with RFC 1483 Encapsulation

In this case the IP address assignment must be static.

6.1.4.3 IP Assignment with ENET ENCAP Encapsulation

In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the ZyXEL Device acts as a DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable (N/A) as the DHCP server assigns them to
the ZyXEL Device.

6.1.5 Nailed-Up Connection (PPP)

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The ZyXEL Device does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the ZyXEL Device will try to bring up the connection when turned on and whenever the connection is down. A nailed-up connection can be very expensive for obvious reasons.
P-2602HWNLI User’s Guide
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a constant connection and the cost is of no concern

6.2 PPPoE Encapsulation

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 service selection. This enables the service provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant 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 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.
Chapter 6 WAN Setup 89
Page 90
P-2602HWNLI User’s Guide

6.3 Metric

The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number greater than "15" means the link is down. The smaller the number, the lower the "cost".
The metric sets the priority for the ZyXEL Device’s routes to the Internet. If any two of the default routes have the same metric, the ZyXEL Device uses the following pre-defined priorities:
• Normal route: designated by the ISP (see Section 6.6 on page 92)
• Traffic-redirect route (see Section 6.10 on page 100)
• WAN-backup route, also called dial-backup (see Section 6.10 on page 100)
For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and dial-backup route has a metric of "3", then the normal route acts as the primary default route. If the normal route fails to connect to the Internet, the ZyXEL Device tries the traffic-redirect route next. In the same manner, the ZyXEL Device uses the dial-backup route if the traffic-redirect route also fails.
If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater).
IP Policy Routing overrides the default routing behavior and takes priority over all of the routes mentioned above.

6.4 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.
90 Chapter 6 WAN Setup
Page 91
P-2602HWNLI User’s Guide
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 43 Example of Traffic Shaping

6.4.1 ATM Traffic Classes

These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification.
6.4.1.1 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.
6.4.1.2 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.
The VBR-RT (real-time Variable Bit Rate) type is used with bursty 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.
Chapter 6 WAN Setup 91
Page 92
P-2602HWNLI User’s Guide
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.
6.4.1.3 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.

6.5 Zero Configuration Internet Access

Once you turn on and connect the ZyXEL Device to a telephone jack, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the ZyXEL Device cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.
Zero configuration for Internet access is disabled when
• the ZyXEL Device is in bridge mode
• you set the ZyXEL Device to use a static (fixed) WAN IP address.
6.6 Internet Access Setup
To change your ZyXEL Device’s WAN remote node settings, click Network > WAN. The screen differs by the encapsulation.
