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).
Page 69: Vpi And Vci
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.

TCP/IP configuration at start-up from a server. You can configure the ZyXEL Device as a DHCP server or disable it. When configured as a server, the ZyXEL Device provides the TCP/IP configuration for the clients. If you turn DHCP service off, you must have another DHCP server on your LAN, or else the computer must be manually configured.
Page 87 Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your ZyXEL Device, but make sure that no other device on your network is using that IP address.

Security Firewalls (111) Firewall Configuration (123) Content Filtering (145)
Page 111: Firewalls
H A P T E R Firewalls This chapter gives some background information on firewalls and introduces the ZyXEL Device firewall. 8.1 Firewall Overview Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term “firewall” is a system or group of systems that enforces an access-control policy between two networks.
Page 112: Application-Level Firewalls
The ZyXEL Device also has packet filtering capabilities. The ZyXEL Device is installed between the LAN and the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
Page 113: Denial Of Service Attacks
Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources. The ZyXEL Device is pre-configured to automatically detect and thwart all known DoS attacks.

Chapter 8 Firewalls 8.4.2 Types of DoS Attacks There are four types of DoS attacks: 1 Those that exploit bugs in a TCP/IP implementation. 2 Those that exploit weaknesses in the TCP/IP specification. 3 Brute-force attacks that flood a network with useless data. 4 IP Spoofing.
Page 115: Figure 60 Syn Flood
Chapter 8 Firewalls Figure 60 SYN Flood • In a LAND Attack, hackers flood SYN packets into the network with a spoofed source IP address of the targeted system. This makes it appear as if the host computer sent the packets to itself, making the system unavailable while the target system tries to respond to itself.
Page 116: Stateful Inspection
To engage in IP spoofing, a hacker must modify the packet headers so that it appears that the packets originate from a trusted host and should be allowed through the router or firewall. The ZyXEL Device blocks all IP Spoofing attempts. 8.5 Stateful Inspection With stateful inspection, fields of the packets are compared to packets that are already known to be trusted.
Page 117: Stateful Inspection Process
Chapter 8 Firewalls are allowed in. The ZyXEL Device uses stateful packet inspection to protect the private LAN from hackers and vandals on the Internet. By default, the ZyXEL Device’s stateful inspection allows all communications to the Internet that originate from the LAN, and blocks all traffic to the LAN that originates from the Internet.
Page 118: Stateful Inspection And The Zyxel Device
Below is a brief technical description of how these connections are tracked. Connections may either be defined by the upper protocols (for instance, TCP), or by the ZyXEL Device itself (as with the "virtual connections" created for UDP and ICMP).
Page 119: Udp/Icmp Security
IP addresses, TCP ports, sequence numbers, etc. When the ZyXEL Device receives any subsequent packet (from the Internet or from the LAN), its connection information is extracted and checked against the cache. A packet is only allowed to pass through if it corresponds to a valid connection (that is, if it is a response to a connection which originated on the LAN).
Page 120: Guidelines For Enhancing Security With Your Firewall
Chapter 8 Firewalls 8.6 Guidelines for Enhancing Security with Your Firewall • Change the default password via CLI (Command Line Interpreter) or web configurator. • Limit who can telnet into your router. • Don't enable any local service (such as SNMP or NTP) that you don't use. Any enabled service could present a potential security risk.

9.1 Access Methods The web configurator is, by far, the most comprehensive firewall configuration tool your ZyXEL Device has to offer. For this reason, it is recommended that you configure your firewall using the web configurator.CLI (Command Line Interpreter) commands provide limited configuration options and are only recommended for advanced users.
Page 124: Rule Logic Overview
These custom rules work by comparing the Source IP address, Destination IP address and IP protocol type of network traffic to rules set by the administrator. Your customized rules take precedence and override the ZyXEL Device’s default rules. 9.3 Rule Logic Overview Study these points carefully before configuring rules.
Page 125: Key Fields For Configuring Rules
LAN to LAN/ Router and WAN to WAN/ Router rules apply to packets coming in on the associated interface (LAN or WAN respectively). LAN to LAN/ Router means policies for LAN-to-ZyXEL Device (the policies for managing the ZyXEL Device through the LAN interface) and policies for LAN-to-LAN (the policies that control routing between two subnets on the LAN).
Page 126: Lan To Wan Rules
Chapter 9 Firewall Configuration 9.4.1 LAN to WAN Rules The default rule for LAN to WAN traffic is that all users on the LAN are allowed non- restricted access to the WAN. When you configure a LAN to WAN rule, you in essence want to limit some or all users from accessing certain services on the WAN.

(bandwidth budgets) to different bandwidth rules. The ZyXEL Device applies bandwidth management to traffic that it forwards out through an interface. The ZyXEL Device does not control the bandwidth of traffic that comes into an interface. Bandwidth management applies to all traffic flowing out of the router, regardless of the traffic's source.
Page 156: Application And Subnet-Based Bandwidth Management
64 Kbps 64 Kbps 12.5 Scheduler The scheduler divides up an interface’s bandwidth among the bandwidth classes. The ZyXEL Device has two types of scheduler: fairness-based and priority-based. 12.5.1 Priority-based Scheduler With the priority-based scheduler, the ZyXEL Device forwards traffic from bandwidth classes according to the priorities that you assign to the bandwidth classes.
Page 157: Fairness-Based Scheduler
160). 12.6.2 Maximize Bandwidth Usage Example Here is an example of a ZyXEL Device that has maximize bandwidth usage enabled on an interface. The following table shows each bandwidth class’s bandwidth budget. The classes are set up based on subnets. The interface is set to 10240 kbps. Each subnet is allocated 2048 kbps.
Page 158: Table 53 Priority-Based Allotment Of Unused And Unbudgeted Bandwidth Example
• The sales and marketing are first to get extra bandwidth because they have the highest priority (6). If they each require 1536 kbps or more of extra bandwidth, the ZyXEL Device divides the total 3072 kbps total of unbudgeted and unused bandwidth equally between the sales and marketing departments (1536 kbps extra to each for a total of 3584 kbps for each) because they both have the highest priority level.

Page 273: Appendix D Ip Addresses And Subnetting
P P E N D I X IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network.
Page 274: Figure 157 Network Number And Host Id
Appendix D IP Addresses and Subnetting Figure 157 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation).
