Configuring Network Use
The V500 system is factory configured to enable you to easily and quickly make
video calls in most network situations. In many cases, you simply need to
physically connect the system as described in Chapter 2, power it on, and follow
the setup wizard.
However, because networks vary from business to business and home to home,
you may need to change some of the default settings or perform other network
configuration. For example, if you’re using a router, you need to configure that
router to allow video calls.
This chapter begins by helping you determine which type of network
configuration you have. It then provides you with the steps you need to take to
prepare your particular network for video calling. It also describes the various IP
and ISDN settings, and which of these you may need to change for your network
environment. For example, if you have a gatekeeper and gateway, this chapter
describes how to configure those.
Once you have done this, you can set your call preferences and, if you choose, set
up your system to use the global directory. Then you’re ready to place your first
test call. This chapter describes how to perform all of these tasks, so that you can
successfully enjoy video calling with your V500 system.

Administrator’s Guide for the V500 System
Using the Setup Wizard
When you power on the system for the first time, a setup wizard begins to run. The
setup wizard automatically detects your system’s IP and ISDN connections, and it
leads you through the minimum steps you need to take to place a video call.
As you go through the setup wizard, you may need additional information or you
may want to change a default setting. If this is your situation, refer to the rest of
this chapter. You will find information there about how to configure your IP and
ISDN connections for your particular network environment.
Establishing an Administrator Password
The setup wizard enables you to set an administrator password, which allows you
to limit access to the Admin Settings. The administrator password may contain
letters and numbers, but no other characters. The default administrator password
is the system’s serial number.
If you change the password, make sure y ou remember it. If you forget the passw ord, you will
have to reset the system, delete the system files, and run the setup wizard again in order to
access the Admin Settings and reset the password. You cannot set the administrator
password from a remote location.
Note that if you establish an administrator’s password during the setup wizard,
you will need to enter it each time you wish to change advanced settings.
Running the Setup Wizard
You can run the setup wizard in either of these two ways.
❑ Directly on the system — Use the remote control to navigate the screens and
enter information. You can use the number pad on the remote control to enter
text just like you can with a cell phone.
❑ From a remote location — Use a web browser to access the V500 web interface.
To do this, your network must be set up and you need to know the IP address
of the system; therefore, this may not be an option if you are installing your
system for the first time in a new location. For more information about remote
management, refer to Managing the System Remotely on page 5-1.

Configuring Your IP Connection
To configure your IP network connection, you need to:
❑ Configure LAN properties
❑ Set up your IP network connection
❑ Configure IP network support
Configuring LAN Properties
The first step in setting up your IP connection is to configure the LAN properties.
If you are connecting your V500 system directly to a cable or DSL modem, before
you begin you need to know the public IP address assigned to your system by your
Internet Service Provider (ISP). Your ISP will provide you with one of these IP
addresses:
❑ Static IP address – This address is reserved for your system and will not
change. When you configure the LAN properties of the system, choose the
Enter IP Address Manually option.
Your ISP should also provide you with the DNS server address, default
gateway address, subnet mask, and WINS server IP address.
Chapter 3 - Configuring Network Use
❑ Dynamic IP address – This address is obtained from your ISP’s DHCP server,
and therefore may change. When you configure the LAN properties of the
system, choose the Obtain IP Address Automatically option.
When you choose this option, the DNS server address, default gateway
address, and other settings should fill in automatically.
To configure LAN properties:
1. Go to System > Admin Settings > LAN Properties.
© Polycom, Inc. 3 - 3
Administrator’s Guide for the V500 System
2. Configure these settings:
Setting Description

Setting Description
LAN Speed Specify the LAN speed to use. Note that the speed you choose
must be supported by the switch.
Choose Auto to have the switch negotiate the speed
automatically. If you choose 10 Mbps or 100 Mbps, you must also
select a duplex mode.
Note: The LAN speed setting for the V500 and the switch must
match. Polycom strongly recommends that you do not select Auto
for either only the V500 or only the router; the settings for both
must be the same. Typically, selecting Auto for both is sufficient.
Duplex Mode Specify the Duplex mode to use. Note that the Duplex mode you
choose must be supported by the switch.
Choose Auto to have the network switch negotiate the Duplex
mode automatically.
Setting Up Your IP Network Connection
The following is a list of the common ways you can connect your V500 to an IP
network so that you can make video calls. Pick out the IP network connection type
that most closely resembles how you plan to make your calls, then read the section
that corresponds to that connection type. If you need help determining how your
V500 connects to the network, contact your network administrator, network
service provider, or Internet Service Provider (ISP).

Through a Router, Using a DMZ on page 3-12.
Calling Within an Intranet
An intranet is a private network within a company or organization. Calls within
an intranet don’t access the Internet, so security isn’t an issue. Even if your
company has a firewall, intranet calls remain within the firewall, so you can easily
communicate with anyone within your office network.

If, therefore, you’re limiting your calls to other systems within your intranet, you
don’t need to perform any additional network configuration to use your V500.
Simply go on to the next section, Configuring IP Network Support on page 3-13.
Calling Through a Cable or DSL Modem
You can access the network and make video calls by directly connecting your V500
to a cable modem or Digital Subscriber Line (DSL) modem, without using a
network router.
If you have a DSL connection and you are in a home environment or your DSL
modem does not maintain a connection state automatically, Polycom recommends
that you use a network router.
Directly connecting your V500 to the network with a cable or DSL modem does not
provide you with a security barrier between your home or business network and
the Internet; however, it is an easy way to set up your V500 network connection.
Systems set up outside a firewall are potentially vulnerable to unauthorized access. Visit the
Polycom Security Center at www.polycom.com for timely security information. You can also
register to receive periodic email updates and advisories.
If your V500 system is directly connected to a cable or DSL modem, you don’t need
to perform any additional network configuration to use your V500. Simply go on
to the next section, Configuring IP Network Support on page 3-13.
Calling Through a Network Router
Network routers let you connect more than one computer, video conferencing
system, or other device to your cable or DSL modem so that they all can share the
same high-speed network connection. This is accomplished by using Network
Address Translation (NAT) services. Routers also often offer firewall protection.
❑ In a typical IP network, all the devices within the network have their own
unique IP address, which is available for everyone in or outside the network
to access. With a NAT, each device within the network retains its own IP
address, but the NAT presents a single IP address to the outside world. This
provides an extra level of security because devices inside the network are
masked behind that single, external IP address.

Chapter 3 - Configuring Network Use
❑ A firewall acts as a security barrier between one network and another. Often
that barrier is between a smaller network, like you might have at your home
or business, and an exterior network, such as the Internet. The firewall
prevents unsolicited external network traffic from accessing your internal
network.
Because NATs and firewalls provide security for your network, they limit outside
access to your internal network. Some access, however, is necessary for video
communications. To enable your V500 to freely place and receive calls with the
outside world, while still maintaining protection for your network, you must open
ports in the firewall. This process is known as port forwarding or pinholing.
The following sections describe the steps you need to take to place video calls
through a network router, including:
❑ Configuring router port forwarding
❑ Configuring firewall and NAT properties on the V500
Configuring Router Port Forwarding
To make video calls with your V500 system when you have a router, you must
open and assign ports in the firewall. This section describes how to do that with
the most common routers from NetGear®, Linksys®, and D-Link®. Most other
routers require similar procedures.
Before you can change your router configuration, you must know:
❑ The IP address of your router, which you can find in your router’s
documentation. (Note that many routers use the default address 192.168.1.1.)
❑ Your router’s administrator name and password, which you can find in your
router’s documentation. (Note that many routers use the default user name
admin and the password blank or password.)
❑ The IP address that has been assigned to your system if you’re using DHCP,
which you can find on the LAN Properties screen. (See Configuring LAN
Properties on page 3-3 for more information.)
With any router brand or model, you must open the ports listed here:
Port Function TCP or UDP
1720 H.323 call setup TCP
3230-3235 Signaling and control for audio, call,
video, and data/FECC
3230-3253 Audio and video R T P media streams UDP
1503 (optional) T.120 data collaboration TCP
TCP

configuration information.
NetGear Routers
The following procedure applies to NetGear MR814v2 and RP614v2 routers. If you
have a different NetGear model, the settings may vary slightly. This procedure
assumes that your router is correctly configured and connected to the Internet and
that your network is operational.
To configure a NetGear router:
1. In a browser such as Internet Explorer, type the IP address of your router,
which you can find in your router’s documentation.
2. Log in to your router setup using the user name and password, which you can
find in your router’s documentation.
3. From the Advanced menu on the left of the page, select Port Forwarding.
4. On the Port Forwarding page, select Add Custom Service.
5. On the Ports-Custom Services page, enter this information for the first port
you need to open (such as port 1720):
Setting Description
Service Name Any unique identifier (for example, you can use the text
