CHAPTER 1
Introducing the ZyWALL
This chapter gives an overview of the ZyWALL. It explains the front panel ports,
LEDs, introduces the management methods, and lists different ways to start or
stop the ZyWALL.
1.1 Overview and Key Default Settings
The ZyWALL is a comprehensive security device. Its flexible configuration helps
network administrators set up the network and enforce security policies efficiently.
In addition, the ZyWALL provides excellent throughput, making it an ideal solution
for reliable, secure service.
The ZyWALL’s security features include VPN, firewall, anti-virus, content filtering,
IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and
Protection), and certificates. It also provides bandwidth management, Instant
Messaging (IM) and Peer to Peer (P2P) control, NAT, port forwarding, policy
routing, DHCP server and many other powerful features. Flexible configuration
helps you set up the network and enforce security policies efficiently. See Chapter
2 on page 39 for a more detailed overview of the ZyWALL’s features.
The ZyWALL provides ex cellent throughput with the reliability of dual WAN Gigabit
Ethernet ports and load balancing. You can also use a 3G cellular card (not
included) for a third WAN connection.
The ZyWALL lets you set up multiple networks for your company. The DeMilitarized Zone (DMZ) increases LAN security by providing separate ports for
connecting publicly accessible servers. The ZyWALL also provides two separate
LAN networks. You can set ports to be part of the LAN1, WLAN, or DMZ.
Alternatively, you can deploy the ZyWALL as a transparent firewall in an existing
network with minimal configuration.
You can insert a wireless LAN card into the PCMCIA/CardBus slot to add an IEEE
802.11b/g-compliant wireless LAN.
Configure the ZyWALL USG 200’s OPT Gigabit Ethernet port as a third WAN port,
an additional LAN1, WLAN, or DMZ port or a separate network.

Chapter 1 Introducing the ZyWALL
1.2 Rack-mounted Installation
The ZyWALL can be mounted on an EIA standard size, 19-inch rack or in a wiring
closet with other equipment. Follow the steps below to mount your ZyWALL on a
standard EIA rack using a rack-mounting kit. Make sure the rack will safely
support the combined weight of all the equipment it contains and that the position
of the ZyWALL does not make the rack unstable or top-heavy. Take all necessary
precautions to anchor the rack securely before installing the unit.
Note: Leave 10 cm of clearance at the sides and 20 cm in the rear.
Use a #2 Phillips screwdriver to install the screws.
Note: Failure to use the proper screws may damage the unit.
1.2.1 Rack-Mounted Installation Procedure
1 Align one bracket with the holes on one side of the Z yW ALL and secure it with the
included bracket screws (smaller than the rack-mounting screws).
2 Attach the other bracket in a similar fashion.

1.5 Starting and Stopping the ZyWALL
Here are some of the ways to start and stop the ZyWAL L.
Always use Maintenance > Shutdown > Shut down or the shutdown
command before you turn off the ZyWALL or remove the power. Not
doing so can cause the firmware to become corrupt.
Table 3 Starting and Stopping the ZyWALL
METHOD DESCRIPTION
Turning on the
power
Rebooting the
ZyWALL
Using the RESET
button
Clicking
Maintenance >
Shutdown >
Shutdown or
using the shutdown
command
Disconnecting the
power
A cold start occurs when you turn on the power to the ZyWA LL. The
ZyWALL powers up, checks the hardware, and starts the system
processes.
A warm start (without powering down and powering up again)
occurs when you use the Reboot button in the Reboot screen or
when you use the reboot command. The ZyWALL writes all cached
data to the local storage, stops the system processes, and then does
a warm start.
If you press the RESET button, the ZyWALL sets the configuration
to its default values and then reboots.
Clicking Maintenance > Shutdown > Shutdown or using the
shutdown command writes all cached data to the local storage and
stops the system processes. Wait for the device to shut down and
then manually turn off or remove the power. It does not turn off the
power.
Power off occurs when you turn off the power to the ZyWALL. The
ZyWALL simply turns off. It does not stop the system processes or
write cached data to local storage.
38
The ZyWALL does not stop or start the system processes when you apply
configuration files or run shell scripts although you may temporarily lose access to
network resources.

CHAPTER 2
Features and Applications
This chapter introduces the main features and applications of the ZyWALL.
2.1 Features
The ZyWALL’s security features include VPN, firewall, anti-virus, content filtering,
IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and
Protection), and certificates. It also provides bandwidth management, NAT, port
forwarding, policy routing, DHCP server and many other powerful features.
The rest of this section provides more information about the features of the
ZyWALL.
High Availability
To ensure the ZyWALL provides reliable, secure Internet access, set up one or
more of the following:
• Multiple WAN ports and configure load balancing between these ports.
• One or more 3G (cellular) connections.
• An auxiliary (backup) Internet connection.
• A backup ZyWALL in the event the master ZyWALL fails (device HA).
Virtual Private Networks (VPN)
Use IPSec, SSL, or L2TP VPN to provide secure communication between two sites
over the Internet or any insecure network that uses TCP/IP for communication.
The ZyWALL also offers hub-and-spoke IPSec VPN.
Flexible Security Zones
Many security settings are made by zone, not by interface, port, or network. As a
result, it is much simpler to set up and to change security settings in the ZyWALL.
You can create y our own custom zones. You can add interfaces and VPN tunnels to
zones.
ZyWALL USG 100/200 Series User’s Guide

Page 40
Chapter 2 Features and Applications
Firewall
The ZyWALL’ s firew all is a stateful inspection firew all. The Z yWALL rest ricts access
by screening data packets against defined access rules. It can also inspect
sessions. For example, traffic from one zone is not allowed unless it is ini tiated by
a computer in another zone first.
Intrusion Detection and Prevention (IDP)
IDP (Intrusion Detection and Protection) can detect malicious or suspicious
packets and respond instantaneously. It detects pattern-based attacks in order to
protect against network-based intrusions. See Section 34.6.2 on page 616 for a
list of attacks that the ZyWALL can protect against. You can also create your own
custom IDP rules.
Anomaly Detection and Prevention (ADP)
ADP (Anomaly Detection and Prevention) can detect malicious or suspicious
packets and respond instantaneously. It can detect:
• Anomalies based on violations of protocol standards (RFCs – Requests for
Comments)
• Abnormal flows such as port scans.
The ZyWALL’s ADP protects against network-based intrusions. See Section 35.3.4
on page 646 and Section 35.3.5 on page 649 for more on the kinds of attacks that
the ZyWALL can protect against. You can also create your own custom ADP rules.
Bandwidth Management
Bandwidth management allows you to allocate network resources according to
defined policies. This policy-based bandwidth allocation helps your network to
better handle applications such as Internet access, e-mail, Voice-over-IP (VoIP),
video conferencing and other business-critical applications.
Content Filter
Content filtering allows schools and businesses to create and enforce Internet
access policies tailored to the needs of the organization.
You can also subscribe to category-based content filtering that allows your
ZyWALL to check web sites against an external database of dynamically-updated
ratings of millions of web sites. You then simply select categories to block or
monitor, such as pornography or racial intolerance, from a pre-defined list.
40
ZyWALL USG 100/200 Series User’s Guide
Page 41
Chapter 2 Features and Applications
Anti-Virus Scanner
With the anti-virus packet scanner, your ZyWALL scans files transmitting through
the enabled interfaces into the network. The ZyWALL helps stop threats at the
network edge before they reach the local host computers.
Anti-Spam
The anti-spam feature can mark or discard spam. Use the white list to identify
legitimate e-mail. Use the black list to identify spam e-mail. The ZyWALL can also
check e-mail against a DNS black list (DNSBL) of IP addresses of servers that are
suspected of being used by spammers.
Application Patrol
Application patrol (App. Patrol) manages instant messenger (IM), peer-to-peer
(P2P) applications like MSN and BitTorrent. You can even control the use of a
particular application’s individual features (like text messaging, voice, video
conferencing, and file transfers). Application patrol has powerful bandwidth
management including traffic prioritization to enhance the performance of delaysensitive applications like voice and video. You can also use an option that gives
SIP priority over all other traffic. This maximizes SIP traffic throughput for
improved VoIP call sound quality.
2.2 Applications
These are some example applications for your ZyWALL. See also Chapter 7 on
page 117 for configuration tutorial examples.

Chapter 2 Features and Applications
2.2.1 VPN Connectivity
Set up VPN tunnels with other companies, branch offices, telecommuters, and
business travelers to provide secure access to your network. You can also set up
additional connections to the Internet to provide better service.
Figure 5 Applications: VPN Connectivity
2.2.2 SSL VPN Network Access
You can configure the ZyWALL to provide SSL VPN network access to remote
users. There are two SSL VPN network access modes: reverse proxy and full
tunnel.
2.2.2.1 Reverse Proxy Mode
In reverse proxy mode, the ZyWALL is a proxy that acts on behalf of the local
network servers (such as your web and mail servers). As the final destination, the
ZyWALL appears to be the serv er to remote users. This provides an added layer of
protection for your internal servers.
With reverse proxy mode, remote users can easily access any web-based
applications on the local network by clicking on links or entering the provided URL.
42
ZyWALL USG 100/200 Series User’s Guide

Chapter 2 Features and Applications
You do not have to install additional client software on the remote user computers
for access.
Figure 6 Network Access Mode: Reverse Proxy
https;//
2.2.2.2 Full Tunnel Mode
In full tunnel mode, a virtual connection is created for remote users with private
IP addresses in the same subnet as the local network. This allows them to access
network resources in the same way as if they were part of the internal network.

5.5.5 VPN Advanced Wizard - Phase 1 Settings
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1
(Authentication) and phase 2 (Key Exchange). A phase 1 exchange establ ishes an
IKE SA (Security Association).
Figure 51 VPN Advanced Wizard: Phase 1 Settings
• Secure Gateway: If Any displays in this field, it is not configurable for the
chosen scenario. If this field is configurable, enter the WAN IP address or
domain name of the remote IPSec device (secure gateway) to identify the
remote IPSec device by its IP address or a domain name. Use 0.0.0.0 if the
remote IPSec device has a dynamic WAN IP address.
• My Address (interface): Select an interface from the drop-down list box to
use on your ZyWALL.
• Negotiation Mode: Select Main for identity protection. Select Aggressive to
allow more incoming connections from dynamic IP addresses to use separate
passwords.
Note: Multiple SAs connecting through a secure gateway must have the same
negotiation mode.
• Encryption Algorithm: 3DES and AES use encryption. The longer the key, the
higher the security (this may affect throughput). Both sender and recei ver must
know the same secret key, which can be used to encrypt and decrypt the
message or to generate and verify a message authentication code. The DES
encryption algorithm uses a 56-bit key. Triple DES (3DES) is a variation on DES
88
ZyWALL USG 100/200 Series User’s Guide
Page 89
Chapter 5 Quick Setup
that uses a 168-bit key. As a result, 3DES is more secure than DES. It also
requires more processing power, resulting in increased latency and decreased
throughput. AES128 uses a 128-bit key and is faster than 3DES. AES192 uses a
192-bit key and AES256 uses a 256-bit key.
• Authentication Algorithm: MD5 gives minimal security. SHA-1 gives higher
security. MD5 (Message Digest 5) and SHA1 (Secure Has h Algorit hm) are hash
algorithms used to authenticate pac ket data. The SHA1 algorithm is generally
considered stronger than MD5, but is slower.
• Key Group: DH5 is more secure than DH1 or DH2 (although it may affect
throughput). DH1 (default) refers to Diffie-Hellman Group 1 a 768 bit random
number. DH2 refers to Diffie-Hellman Group 2 a 1024 bit (1Kb) random number.
DH5 refers to Diffie-Hellman Group 5 a 1536 bit random number.
• SA Life Time: Set how often the ZyWALL renegotiates the IKE SA. A short SA
life time increases security, but renegotiation temporarily disconnects the VPN
tunnel.
• NAT Traversal: Select this if the VPN tunnel must pass through NAT (there is a
NAT router between the IPSec devices).
Note: The remote IPSec device must also have NAT traversal enabled. See VPN,
NAT, and NAT Traversal on page 512 for more information.
• Dead Peer Detection (DPD) has the ZyWALL make sure the remote IPSec
device is there before transmitting data through the IKE SA. If there has been
no traffic for at least 15 seconds, the ZyWALL sends a message to the remote
IPSec device. If it responds, the ZyWALL transmits the data. If it does not
respond, the ZyWALL shuts down the IKE SA.
• Authentication Method: Select Pre-Shared Key to use a password or
Certificate to use one of the ZyWALL’s certificates.

IPSec.
Figure 52 VPN Advanced Wizard: Step 4
• Active Protocol: ESP is compatible with NAT, AH is not.
• Encapsulation: Tunnel is compatible with NAT, Transport is not.
• Encryption Algorithm: 3DES and AES use encryption. The longer the AES
key, the higher the security (this may affect throughput). Null uses no
encryption.
• Authentication Algorithm: MD5 gives minimal security. SHA-1 gives higher
security. MD5 (Message Digest 5) and SHA1 (Secure Has h Algorit hm) are hash
algorithms used to authenticate pac ket data. The SHA1 algorithm is generally
considered stronger than MD5, but is slower.
• SA Life Time: Set how often the ZyWALL renegotiates the IKE SA. A short SA
life time increases security, but renegotiation temporarily disconnects the VPN
tunnel.
• Perfect Forward Secrecy (PFS): Disabling PFS allows faster IPSec setup, but is
less secure. Select DH1, DH2 or DH5 to enable PFS. DH5 is more secure than
DH1 or DH2 (although it may affect throughput). DH1 refers to Diffie-Hellman
Group 1 a 768 bit random number. DH2 refers to Diffie-Hellman Group 2 a 1024
bit (1Kb) random number. DH5 refers to Diffie-Hellman Group 5 a 1536 bit
random number (more secure, yet slower).
• Local Policy (IP/Mask): Type the IP address of a computer on your network.
You can also specify a subnet. This must match the remote IP address

CHAPTER 6
Configuration Basics
This information is provided to help you configure the ZyW ALL effectively. Some of
it is helpful when you are just gett i n g st a r t ed. Some of it is provided for your
reference when you configure various features in the ZyWALL.
• Section 6.1 on page 93 introduces the ZyWALL’s object-based configuration.
• Section 6.2 on page 94 introduces zones, interfaces, and port groups.
• Section 6.3 on page 97 introduces some differences in terminology and
organization between the ZyWALL and other routers, particularly ZyNOS
routers.
• Section 6.4 on page 99 covers the ZyWALL’s packet flow.
• Section 6.5 on page 102 identifies the features you should configure before and
after you configure the main screens for each feature. For example, if you want
to configure a trunk for load-balancing, you should configure the member
interfaces before you configure the trunk. After you configure the trunk, you
should configure a policy route for it as well. (You might also have to configure
criteria for the policy route.)
• Section 6.6 on page 113 identifies the objects that store information used by
other features.
• Section 6.7 on page 114 introduces some of the tools available for system
management.
6.1 Object-based Configuration
The ZyWALL stores information or settings as objects. You use these objects to
configure many of the ZyWALL’s features and settings. Once you configure an
object, you can reuse it in configuring other features.
When you change an object’s settings, the ZyWALL automatically updates al l the
settings or rules that use the object. For example, if you create a schedule objec t,
you can have firewall, applicat ion patrol, content filter, and other settings use it. If
you modify the schedule, all the firewall, application patrol, content filter, and
other settings that use the schedule automatically apply the updated schedule.
You can create address objects based on an interface’s IP address, subnet, or
gateway. The Z y WALL automatically updates every rule or setting that uses these
ZyWALL USG 100/200 Series User’s Guide
93
Page 94
Chapter 6 Configuration Basics
objects whenever the interface’s IP address settings change. For example, if you
change an Ethernet interface’s IP address, the ZyWALL automatically updates the
rules or settings that use the interface-based, LAN subnet address object.
You can use the Configuration > Objects screens to create objects before you
configure features that use them. If you are in a screen that uses objects, you can
also usually select Create new Object to be able to configure a new object. F or a
list of common objects, see Section 6.6 on page 113.
Use the Object Reference screen (Section 3.3.3.3 on page 58) to see what
objects are configured and which configuration settings reference specific objects.
6.2 Zones, Interfaces, and Physical Ports
Zones (groups of interfaces and VPN tunnels) simplify security settings. Here is an
overview of zones, interfaces, and physical ports in the ZyWALL.

(P1, P2, ...)
A zone is a group of interfaces and VPN tunnels. Use zones to apply
security settings such as firewall, IDP, remote management, antivirus, and application patrol. You can change the opt interface to be
part of a different zone.
Interfaces are logical entities that (layer-3) packets pass through.
Use interfaces in configuring VPN, zones, trunks, device HA, DDNS,
policy routes, static routes, HTTP redirect, and NAT.
Port roles combine physical ports into interfaces.
The physical port is where you connect a cable. In configuration, you
use physical ports when configuring port groups. You use interfaces
and zones in configuring other features.
6.2.1 Interface Types
There are many types of interfaces in the ZyWALL. In addition to being used in
various features, interfaces also describe the network that is directly connected to
the ZyWALL.
Chapter 6 Configuration Basics
• Ethernet interfaces are the foundation for defining other interfaces and
network policies. Y o u also configure RIP and OSPF in these interfaces.
• Port groups create a hardware connection between physical ports at the layer2 (data link, MAC address) level. Port groups are created when you use the
Interface > Port Roles screen to set multiple physical ports to be part of the
same (lan1, ext-wlan or dmz) interface.
• PPP interfaces support Point-to-Point Protocols (PPPoE or PPTP). ISP accounts
are required for PPPoE/PPTP interfaces.
• VLAN interfaces recognize tagged frames. The ZyWALL automatically adds or
removes the tags as needed. Each VLAN can only be associated with one
Ethernet interface.
• Bridge interfaces create a software connection between Ethernet or VLAN
interfaces at the layer-2 (data link, MAC address) level. Then, you can configure
the IP address and subnet mask of the bridge. It is also possible to configure
zone-level security between the member interfaces in the bridge.
• Virtual interfaces increase the amount of routing information in the ZyWALL.
There are three types: virtual Ethernet interfaces (also known as IP alias),
virtual VLAN interfaces, and virtual bridge interfaces.
•The auxiliary interface, along with an external modem, provides an interface
the ZyWALL can use to dial out. This interface can be used as a backup WAN
interface, for example. The auxiliary interface controls the AUX port.

• The WAN zone contains the wan1 and wan2 interfaces (physical ports P1 and
P2). They use public IP addresses to connect to the Internet.
• OPT is specific to the ZyWALL USG 200.The OPT zone contains the opt interface
(physical port P3). The opt interface is the only default interface that you can
change to be part of a different zone. The opt interface belongs to the OPT zone
by default. The OPT zone is a separate zone and you can configure a different
set of security policies for it.
• The LAN1 zone contains the lan1 interface (a port group made up of physical
ports P4 and P5 on the ZyWALL USG 200 or P3, P4, and P5 on the ZyWALL
USG 100). The LAN1 zone is a protected zone. The lan1 interface uses
192.168.1.1 and the connected devices use IP addresses in the 192.168.1.2 to
192.168.1.254 range.
• The WLAN zone contains the ext-wlan interface (physical port P6). This is a
second protected zone for connecting wireless access points. The ext-wlan
interface uses private IP address 10.59.0.1 and the connected devices use IP
addresses in the 10.59.0.2 to 10.59.0.254 range.
• The DMZ zone contains the dmz interface (physical port P7). The DMZ zone has
servers that are available to the public. The dmz interface uses private IP
address 192.168.3.1 and the connected devices use private IP addresses in the
192.168.3.2 to 192.168.3.254 range.
6.3 Terminology in the ZyWALL
This section highlights some differences in terminology or organization between
the ZLD-based ZyWALL and other routers, particularly ZyNOS routers.

6.4 Packet Flow
Here is the order in which the ZyWALL applies its features and checks.
Figure 58 Packet Flow
Chapter 6 Configuration Basics
6.4.1 ZLD 2.20 Packet Flow Enhancements
ZLD version 2.20 has been enhanced to simplify configuration. The packet flow
has been changed as follows:
• Automatic SNAT and WAN trunk routing for traffic going from internal to
external interfaces (you don’t need to configure anything to all LAN to WAN or
WLAN to WAN traffic).
The ZyWALL automatically adds al l of the external interfaces to the default W AN
trunk. External interfaces include ppp, cellular, and AUX interfaces as well as
any Ethernet interfaces that are set as external interfaces.
Examples of internal interfaces are WLAN interfaces and any Ethernet interfaces
that you configure as internal interfaces.
• A policy route can be automatically disabled if the next-hop is dead.
• You do not need to set up policy routes for IPSec traffic.
• Policy routes can override direct routes.

Chapter 6 Configuration Basics
• You do not need to set up policy routes for 1:1 NAT entries.
• You can create Many 1:1 NAT entries to translate a range of private network
addresses to a range of public IP addresses
• Static and dynamic routes have their own category.
Even with these changes, you can still use an existing configuration file from the
previous version.
6.4.2 Routing Table Checking Flow Enhancements
When the ZyWALL receives packets it defragments them and applies destination
NAT. Then it examines the packets and determines how to route them. The
following figure shows how the ZLD 2.20 firmware’s routing table compares with
the earlier 2.1x firmware’s routing table.The checking flow is from top to bottom.
As soon as the packets match an entry in one of the sections, the ZyWALL stops
checking the packets against the routing table and moves on to the other checks,
for example the firewall check.
Figure 59 Routing Table Checking Flow Enhancements
100
1 Direct-connected Subnets: The ZyWALL first checks to see if the packets are
destined for an address in the same subnet as one of the ZyWALL’ s interfaces. You
can override this and have the ZyWALL check the policy routes first by enabling
the policy route feature’s Use Policy Route to Override Direct Route option
(see Section 15.1 on page 383).
