Preventing Toll Fraud
“Toll fraud” is the unauthorized use of your
telecommunications system by an unauthorized party (for
example, a person who is not a corporate employee, agent,
subcontractor, or is not working on your company's behalf).
Be aware that there may be a risk of toll fraud associated with
your system and that, if toll fraud occurs, it can result in
substantial additional charges for your telecommunications
services.
Avaya Fraud Intervention
If you suspect that you are being victimized by toll fraud and
you need technical assistance or support, in the United
States and Canada, call the Technical Service Center's Toll
Fraud Intervention Hotline at 1-800-643-2353.
Providing Telecommunications Security
Telecommunications security (of voice, data, and/or video
communications) is the prevention of any type of intrusion to
(that is, either unauthorized or malicious access to or use of)
your company's telecommunications equipment by some
party.
Your company's “telecommunications equipment” includes
both this Avaya product and any other voice/data/video
equipment that could be accessed via this Avaya product
(that is, “networked equipment”).
An “outside party” is anyone who is not a corporate
employee, agent, subcontractor, or is not working on your
company's behalf. Whereas, a “malicious party” is anyone
(including someone who may be otherwise authorized) who
accesses your telecommunications equipment with either
malicious or mischievous intent.
Such intrusions may be either to/through synchronous (timemultiplexed and/or circuit-based) or asynchronous
(character-, message-, or packet-based) equipment or
interfaces for reasons of:
• Utilization (of capabilities special to the accessed
equipment)
• Theft (such as, of intellectual property, financial assets, or
toll-facility access)
• Eavesdropping (privacy invasions to humans)
• Mischief (troubling, but apparently innocuous, tampering)
• Harm (such as harmful tampering, data loss or alteration,
regardless of motive or intent)

Typical SG203/SG208 security gateway installation
Functional overview
The SG203 and SG208 security gateways are dedicated hardware-based
network security devices designed to provide overlay security services on
an IP data network. The security gateway sits behind an edge router and
has auto-detecting ethernet interfaces on the public and private ports.
The security gateway’s primary function is to perform IPSec and firewall
security services to protect enterprise networks and to secure data being
sent over shared IP networks. The security gateway establishes an
Internet Key Exchange (IKE) protocol session with its IPSec peer to
perform an authentication and to negotiate the security associations
(SAs) that are used to secure the session. Once the successful
10 Introduction

negotiation is completed data can then be encapsulated in IPSec
tunneling packets that can only be decrypted by the peer on the other end
of the IPSec tunnel.

Encryption
DES, Triple DES, and AES hardware encryption. DES
uses a 56-bit key. Triple DES uses three 56-bit
independent keys for an effective key length of 168 bits.
AES is a symmetric 127 bit block data encryption
technique. AES can be used in place of DES.
All weak and semi-weak keys are automatically
discarded.

VPNmanager
Avaya VPNmanager is an optional Avaya application that lets network
managers define, configure and manage VPNs from any location. Large
networks would want to use VPNmanager to do distributed managed
firewall rules as well as VPN management across the network.
Security
The SG203 and SG208 security gateway employs cryptographic
algorithms and keys powerful enough for the most sensitive business
communications to provide data stream privacy. It supports DES and
Triple DES, and AES encryption, as well as the ISAKMP key
management standard.
March 2004
Introduction
11
Avaya SG203/SG208 Security Gateway Hardware Installation Guide
Data authenticity is assured by using HMAC-MD5™ or HMAC-SHA-1
packet signatures to reject altered or forged packets. All security
mechanisms employed by the security gateway conform to IPSec
standards, in order to provide interoperability and broaden the use of VPN
technology.
Performance
For maximum network flexibility, the SG203 security gateway supports
four 10/100BASE-T Ethernet interfaces, and the SG208 supports four 10/
100/1000BASE-T Ethernet interfaces.
When packets are encrypted and authenticated according to IPSec
protocol guidelines, additional bytes, in the form of IPSec headers, must
be added to packets. In many cases, the additional packet overhead
imposes a performance penalty in return for security. The extra bytes tend
to lengthen packets and reduce the throughput (measured in packets per
second). The overhead depends on the IPSec policy and could be up to
63 bytes.

Plug-and-Play installation
The auto sensing interfaces of the security gateway enables installation
into any Ethernet network. By default, the security gateway functions as a
DHCP client on the public interface and as a DHCP server on the private
interface. Immediately after receiving IP connectivity, the network
administrator can locate the security gateway via https://192.168.1.1 on
the private interface. The administrator enters the name as root and the
password as password for the user’s credentials. The quick set up guides
the network administrator through the minimal network configuration.

Avaya SG203/SG208 Security Gateway Hardware Installation Guide
Rackmount
The SG203 and SG208 security gateways can be mounted in a standard
19-inch equipment rack. The location of the chassis and the layout of your
equipment rack or wiring room are extremely important for proper system
operation. Equipment placed too close together, inadequate ventilation,
and inaccessible panels can cause system malfunctions and shutdowns
and can make system maintenance difficult.
The following information can help you plan an acceptable equipment
rack configuration.
• Enclosed racks must have adequate ventilation. Ensure that the rack
is not overly congested because each unit generates heat. An
enclosed rack should have louvered sides and a fan to provide cooling
air.
• When mounting a chassis in an open rack, ensure that the rack frame
does not block the ventilation grates. If the chassis is installed on
slides, check the position of the chassis when it is seated all the way
into the rack.
To attach the device to a standard 19-inch equipment rack:
1.
From one side of the device, remove the four front side screws.
2.
Using the screws provided with the bracket, attach the bracket to the
device.

uses a straight-through cable when connecting to a hub or switch. The
SG208 can use any type of cable (crossover or straight-through) when
connecting to a hub, switch, or router.
NOTE: To realize maximum performance when operating at the 1000
Base-T rate, it is necessary to use CAT5e cables, shipped with the
device. Standard CAT5 cables are not rated for full Gigabit data rates.
Connecting the SG203/SG208 security gateway to the
network
The supplied Cat5e cables are used to connect the security gateway to
the public network and the private LAN. Figure 6 shows a typical network
using the SG203 and SG208 security gateway.

Note: If DHCP related functionality (DHCP server on the private
interface and DHCP client on the public network) disrupts your
network, change the default settings via the console port, prior to
plugging in the ethernet cables.
2.
Connect one end of the Cat5e straight-through cable to the private
port (Ethernet0) on the security gateway. Connect the other end to the
LAN hub or switch.
Note: A crossover cable is required if the SG203 security gateway is
connected directly to a workstation.
3.
Connect the power cable to the security gateway and then plug it in to
an AC outlet.
4.
Power on the security gateway and proceed to Chapter 3, Setting up
the security gateway for configuration.
The following are the default values for the security gateway.
• DHCP Client public interface is enabled
• DHCP Server private interface is enabled
• Private Interface IP address is 192.168.1.1
• Administrative user name is root
• Password is password

Chapter 3 Setting up the security gateway for
configuration
This chapter describes how to set up the security gateway addressing
and remote connectivity capabilities. This preliminary configuration is
performed using a browser on your workstation connected to the security
gateway’s private port. When the security gateway is initially installed and
connected to the local LAN, it is provisioned with a default IP address for
the DHCP server (serving the private port), allowing access to the device
through a Web browser on a workstation.
The following procedure assumes that the security gateway has been
physically installed on the network, according to the instructions provided
in Chapter 2, Installing SG203 and SG208 Security Gateway.
The security gateway quick setup consists of two basic steps:
1.
Establishing connectivity between a workstation or IP device on your
local network with the security gateway’s private port
2.
Setting up the security gateway’s public port to reach the Internet
Through the Web interface, you can assign a static IP address for the
public port, a password, server addresses, DHCP settings, and a default
gateway. Once this has been done, the security gateway can be
completely configured and incorporated into your Virtual private Network
either by using the Web interface locally, or using Avaya VPNmanager
from a central location.

Setting up the security gateway for configuration 23
Avaya SG203/SG208 Security Gateway Hardware Installation Guide
Connecting to the private port
From the workstation’s control panel, select your TCP/IP network
component for your Ethernet controller. In the IP Address window select
“enable the setting” to “Obtain an IP address automatically” .
Restart your workstation, if the operating system asks you to do so. As
your workstation restarts, it automatically obtains its required IP address/
mask and default router IP address from the security gateway.
NOTE: Unless you have other DNS servers at your local site, it is
recommended that the Windows DNS and WINS server lists be empty.
The DNS server built into the security gateway should normally be the
sole DNS server that users see.
Performing the quick setup
Quick Setup collects and preconfigures the essential information required
to remotely configure and manage the security gateway.
Note: If the security gateway is to be configured and managed locally,
see the Security Gateway Configuration Guide for the VPNos, to perform
a comprehensive device configuration.
The Quick Setup wizard collects the necessary information to
communicate with the remote VPNmanager application through the
security gateway’s public port. The following information is required to
complete the quick setup:
• The type of addressing to be used on the security gateway’s public
port, either Static IP Addressing, Dynamic Addressing (DHCP), or
PPPoE. Typically, DSL connections use PPPoE and cable modems
use DHCP. The default is DHCP
• A network mask for the above
• A default route. This is the service provider’s router used only if Static
IP Address is selected
• The user name and password, if your connection to your ISP is PPPoE

Quick Setup Dialog
The Quick Setup wizard dialog appears. In the IP Configuration area,
select one of the following IP Config Modes.
• Static Addressing. If you are going to use static addressing on the
public port, click the Static Addressing radio button and enter your
IP address, network mask, and default route information.
• DHCP. If you plan to use DHCP, the public port automatically
obtains its address from a DHCP server. This method is typical for
cable modem connections.
• PPPoE. This method is typically used with DSL connections. Click
the PPPoE radio button and enter your PPPoE user name and
password.
7.
Depending on the IP config mode selected, complete the fields that
populate the dialog.
• For Static, enter the IP address, mask and route
• For PPPoE, enter the user name and password

In the Centralized Management area, if VPNmanager is used, enter
the superuser name and password.
9.
In the Date & Time area, enter the date, time, and time zone.
A 24-hour clock is used. For example, 13:00:00 is equivalent to
1:00 PM.
10.
Click Save and then click Log Out from the main page to log of the
Web interface.
NOTE: When you use Log out, you are prompted to save any unsaved
changes before exiting. If you close your browser, unsaved changes are
lost.
You now have entered enough information to allow the security gateway
to be accessed over the Internet. The remaining configuration process
can be completed remotely, using VPNmanager, or if the security
gateway is managed locally, you can continue the configuration. Refer to
the Security Gateway Configuration Guide for VPNos.
