Using a VPN Connection to Remotely Access Lutron® Systems
Overview
This application note describes a method of configuring remote access to a Lutron® system using an Internet connection
to a Virtual Private Network (VPN) router. This application note covers configuring a router to use Point to Point Tunneling
Protocol (PPTP) for VPN access. Microsoft Windows XP®, Windows Vista®, and Windows® 7 have native client support for
this type of VPN.
PPTP VPN adds a layer of security before the homeowner’s system is connected to the Internet. It should be noted that
any time remote access is provided for a homeowner’s site there is a risk of having the network and equipment
compromised by unauthorized access.
Key Terms
VPN
VPN Router
VPN Client
ISP
Static IP
Dynamic IP
URL
DNS Server
Dynamic DNS
Virtual Private Network
A piece of hardware or software that provides a virtual connection through a public network (such as
the internet) to a private network.
Hardware or software that connects to a VPN router over a public network connection and provides an
additional network connection to the private network which the VPN router is connected to.
Internet Service Provider
An IP address assigned to a network computer or device which does not change at a given time
interval or during the network connection process.
An IP address assigned to a network computer or device which changes at a predetermined time
interval or during the network connection process.
Universal Resource Locator: a readable name that represents a network IP address (i.e. google.com or
myname.dyndns.org). A URL is often referred to as a host name or web address.
A server on a public or private network that translates URL’s into network IP addresses.
A service that maps static or dynamic IP address to a URL.
Before You Begin…
1.
In order to connect to a VPN router the VPN client must be able to find the VPN router. This is done with one of the
following two options:
a.
A static IP address from the client’s ISP. This address must be known to complete the setup and will be provided
by the ISP.
b.
An account with a dynamic DNS service. This application note uses DynDNS.org. This will allow the use of a host
name (URL) instead of a static IP.
2. Acquire a VPN router and its accompanying manual. This application note covers the use of the D-Link® DIR-130
(wired) and the D-Link® DIR-330 (wired/wireless) routers. Please note that all screenshots within this application note
may differ in appearance to the screens rendered on your computer. This application note also assumes the
router is in its “default” or “out-of-box” state. If this is not the case, there is a risk of running an untested VPN

router environment incompatible with Lutron® systems. See “Appendix C – Technical Specifications” subsection
“Default Factory Settings” of the router’s product manual for instructions on performing a reset.
3.
Ensure each HomeWorks® IlluminationTM/QS Processor or the RadioRA® 2 Main Repeater is using a static IP address
and you have those addresses readily available. Static IP addresses are required to ensure devices using the VPN
remotely can locate the system.
4.
Confirm the PC you will be using to configure the VPN Router is set to obtain an IP address dynamically. Please
reference the following Microsoft Windows® articles for support:
a.
Windows XP®: http://support.microsoft.com/kb/305553
b.
Windows Vista®: http://windows.microsoft.com/en-US/windows-vista/Change-TCP-IP-settings

Configuring the Router
1.
2.
Setup a private network with the VPN router: Follow the manufacturer’s instructions included with the router to
connect computers and other network devices to the router.
a.
The manufacturer’s instructions can be found on the CD included with the VPN router. Insert the CD into
your PC and select “View Manual”. Follow the instructions under “Section 1: Product Overview” and
“Section 2: Installation” of the manual.
b.
Access the router’s internal configuration pages. To access these pages, open a web-browser and enter
the IP address of the D-Link VPN router (192.168.0.1).
c.
Enter admin as the User name. Leave the password field blank.
Verify the VPN router has the latest firmware: Once logged into the router’s configuration pages, ensure that
the Firmware Version is version 1.12 or higher (D-Link DIR-330) or 1.23 or higher (D-Link DIR-130). If it is lower,
upgrade the firmware by following the manufacturer’s instructions before proceeding. The current firmware
version information can be found in the top right-hand corner of any router configuration page.
Figure 1
3.
Configure the VPN router for remote access: Changes need to be made to the router’s default configuration in
order to setup the router for remote access. Each change is listed below.
Note: Make sure to press the Save Settings button at the top of every configuration screen when indicated in the
following steps. Otherwise the changes that have been made will not be saved. After pressing the Save Settings
button, it may take a few moments until the Continue button is enabled to click.
a.
Configure the VPN router’s local network settings:
Note: The default LAN IP address is set to 192.168.0.1. If a VPN client’s local network uses IP
addresses in the same range as the VPN router’s network (192.168.0.XXX), an address conflict may
occur and the connection between the VPN client and the VPN router will not operate properly. To
reduce the possibility of address conflicts, Lutron recommends changing the default (VPN) LAN IP
address to something less likely used as default addresses on other local networks. In this example, we
will use 192.168.100.1 as the (VPN) LAN IP address.
i. Select the Setup tab from the top menu, and then select Network Settings from the left menu.
ii. Modify the network address as shown in Figure 2.

Lutron® Technical Support Center
1.800.523.9466
Application Note #231 – Using a VPN Connection to Remotely Access Lutron® Systems
1.
Set the Router IP Address to 192.168.100.1
2.
Ensure the Default Subnet Mask is 255.255.255.0
3.
Ensure the Local Domain Name is blank.
4.
Ensure the Enable DNS Relay is checked.
5.
Press the Save Settings button at the top.
iii. Restart the computer that is connected to the router in order for it to acquire its new IP address.
Then re-open a web browser and enter the new IP address of the VPN router (192.168.100.1).
Figure 2
b.
Configure the VPN router’s Internet connection settings:
i. If the ISP provides a static IP address the VPN router must be configured with a static Internet IP
address:
1.
Access the VPN Router’s internal configuration pages at its address: 192.168.100.1
2.
Select the Setup tab.
3.
Click Internet from the left menu.
4.
Under Manual Internet Connection Options, select the Manual Configure button.
5.
Change My Internet Connection is to Static IP.
6.
Fill in the IP Address, Subnet Mask, ISP Default Gateway Address, MAC Address,
and DNS Servers your ISP has provided.

7.
Press the Save Settings button at the top.
Figure 3
ii. If the ISP provides a Dynamic IP address a dynamic DNS service must be used. Dynamic DNS
services can be used with static IP addresses as well to utilize a custom web address instead of a
static IP address when directing the VPN client device to the VPN router over the Internet. This
can be done using a dynamic DNS hosting service such as DynDNS.org. This application note
uses a DynDNS.org free account. To configure a dynamic DNS service:
1.
Access the VPN Router’s internal configuration pages at its address: 192.168.100.1
2.
Select the Maintenance tab.
3.
Click Dynamic DNS from the left menu.
4.
Check Enable Dynamic DNS to enable.
5.
Select www.DynDns.org (Free) and click the << button to populate Server Address.
6.
Provide the correct Host Name, User Name, and Password, for the DynDNS.org
account being used.
