4 Plan the Installation
Decide how you are going to configure the Cisco S170 Web
Security Appliance within your network.
The Cisco S170 appliance is typically installed as an additional
layer in the network between clients and the Internet.
Depending on how you deploy the appliance, you may or may
not need a Layer 4 (L4) switch or a WCCP router to direct client
traffic to the appliance.
Deployment options include:
• Transparent Proxy—Web proxy with an L4 switch
• Transparent Proxy—Web proxy with a WCCP router
• Explicit Forward Proxy—Connection to a network switch
• L4 Traffic Monitor—Ethernet tap (simplex or duplex)
– Simplex Mode: Port T1 receives all outgoing traffic,
and port T2 receives all incoming traffic.
– Duplex Mode: Port T1 receives all incoming and
outgoing traffic.

Note To monitor true client IP addresses, the L4 traffic
monitor should always be configured inside the firewall
and before NAT (Network Address Translation).
5 Install the Appliance in a Rack
Install the Cisco S170 Web Security Appliance using either the
slide rails or fixed rack mount brackets. For information about
these installation options, see the Cisco 170 Series Hardware
Installation Guide.
Appliance Placement in a Rack
• Ambient Temperature—To prevent the appliance from
overheating, do not operate it in an area that exceeds an
ambient temperature of 104°F (40°C).
• Air Flow—Be sure that there is adequate air flow around
the appliance.
• Mechanical Loading—Be sure that the appliance is level
and stable to avoid any hazardous conditions.

You can log in to the Cisco S170 appliance using one of two
interfaces: the web-based interface or the command-line
interface.
Web-Based Interface
Step 1 For web browser access via the Ethernet port (see the
“Connect to the Appliance” section on page 12), go to
the Cisco S170 appliance management interface by
entering the following URL in a web browser:
http://192.168.42.42

Step 2 Enter the following login information:
• Username: admin
• Password: ironport
Note The hostname parameter is assigned during system
setup. Before you can connect to the management
interface using a hostname (http://hostname:8080), you
must add the appliance hostname and IP address to
your DNS server database.
Step 3 Click Login.
Command-Line Interface
Step 1 For command-line interface access via the serial port
(see the “Connect to the Appliance” section on page 12),
access the command-line interface by SSH or a terminal
emulator using 9600 bits, 8 bits, no parity, 1 stop bit
(9600, 8, N, 1) and flow control set to Hardware.
Step 2 Initiate a session to the IP address 192.168.42.42.
Step 3 Log in as admin with the password ironport.
Step 4 At the prompt, run the systemsetup command.

11 Run the System Setup Wizard
The System Setup Wizard starts automatically when you access
the appliance via the web-based interface (or when you run the
systemsetup command from the command-line interface) and
displays the end user license agreement (also known as the
EULA).
Step 1 Start the System Setup Wizard.
Step 2 Accept the end user license agreement.
Step 3 Enter registration information.
Step 4 Enter information from the “Document Network
Settings” section on page 3.
Step 5 Set web security settings.
Step 6 Review the configuration summary page.
Step 7 Log back in to the appliance with the username admin
and the new password that you set in the System Setup
Wizard.
The Cisco S170 Web Security Appliance uses a
self-signed certificate that may trigger a warning from
your web browser. You can simply accept the certificate
and ignore this warning.
Step 8 Write down your new administrator password and
keep it in a safe place.

12 Configure Network Settings
Depending on your network configuration, your firewall may
need to be configured to allow access using the following ports.
SMTP and DNS services must have access to the Internet.
The web security appliance must be able to listen on the
following ports:
• FTP: port 21, data port TCP 1024 and higher
• HTTP: port 80
• HTTPS: port 443
• Management access: ports 8443 (HTTPS) and 8080
(HTTP)
• SSH: port 22
The web security appliance must be able to make an outbound
connection on the following ports:
• DNS: port 53
• FTP: port 21, data port TCP 1024 and higher
• HTTP: port 80
• HTTPS: port 443
• LDAP: port 389 or 3268
• LDAP over SSL: port 636
• LDAP with SSL for global catalog queries: port 3269
• NTP: port 123
• SMTP: port 25
Note If you do not open port 80 and 443, you cannot
download feature keys.

13 Configuration Summary
Item Description
Management You can manage the web security appliance
from the management port (MGMT port)
by entering http://192.168.42.42:8080
or by using the IP address assigned to the
management interface after you have
completed the System Setup Wizard.
If you reset your configuration to factory
default settings (for example, by re-running
the System Setup Wizard), you can access
the management interface only from the
MGMT port (http://192.168.42.42:8080),
so ensure that you have a connection to the
MGMT port.
Also, verify that you open firewall ports 80
and 443 on your management interface.
Data After running the System Setup Wizard, at
least one port on the appliance is configured
to receive web traffic from the clients on the
network: M1 only; M1 and P1;
M1, P1 and P2; P1 only; or P1 and P2.
Note If you configured the web proxy in
explicit forward mode, the
applications on the client machines
must be configured to explicitly
forward web traffic to the web
security appliance’s web proxy
using the IP address configured for
data, either M1 or P1.
S170_QSG.fm Page 17 Wednesday, March 13, 2013 10:23 PM

18
Traffic Monitor After running the System Setup Wizard, one
or both L4 traffic monitor ports (T1 only or
both T1 and T2) are configured to listen to
traffic on all TCP ports. The default setting
for the L4 traffic monitor is monitor only.
During or after setup, you can configure the
L4 traffic monitor to both monitor and
block suspicious traffic.
Computer
Address
Remember to change your computer IP
address back to the original settings that
you noted in the “Temporarily Change Your
IP Address” section on page 10.

14 You’re Done!
Congratulations. You are now ready to start using your
Cisco S170 Web Security Appliance. You may wish to consider
taking some of the following steps to get more out of the
appliance:
User Policies
Use the web interface to create policies that define which users
can access which web resources as necessary.
• Identify Users—Choose Web Security Manager > Identities
to define groups of users that can access the Internet.
• Define Access Policies—Choose Web Security Manager >
Access Policies to control user access to the Internet by
configuring which objects and applications to allow or
block, which URL categories to monitor or block, and web
reputation and anti-malware settings.
You can also define several other policy types to enforce your
organization’s acceptable use policies by controlling access to
the Internet. For example, you can define policies for decrypting
HTTPS transactions and other polices that control upload
requests.
For information about configuring policies on the Cisco S170
appliance, see the “Working with Policies” chapter in the Cisco
IronPort AsyncOS for Web User Guide.
Reporting
You can view statistics about blocked and monitored web traffic
on your network by viewing reports available in the web
interface. You can view reports about the top URL categories
blocked, client activity, system status, and more.
