A.6.5 Proxy  

The proxy feature allows you to access a ZonePRO over a complex or remote network.   An
example of this is when the PC and the ZonePRO reside on different subnets. The mechanism
that is used by default for the ZonePRO designer software to discover and maintain a connec-
tion to the ZonePRO units utilizes IP broadcast packets.  These packets will not travel through
internet routers and even some high end core switches.   In order to connect to one or more
ZonePRO 1260/1261s that are attached to a complex network proxy is used to tell the Designer
software where on the network to look for the ZonePRO devices.  

There only needs to be one

proxy setup for each group of ZonePROs that are on the same local network.  The device that is
the proxy will pass information to the other ZonePROs that it sees on the network that will allow
them to connect to the ZonePRO Designer software.

Follow these steps to setup a proxy connection:

1. Make sure that the ZonePRO has been correctly configured for the network that it is on

and that the PC that is running the ZonePRO Designer software has a network connec-
tion to that 1260 / 1261 device.  You should be able to ping from the windows box to
the ZonePRO.

2. Select Properties from the Network menu of the main ZonePRO Designer window.
3. Make sure that “Use Ethernet” selected.
4. Select “Advanced.”
5. Press the Add… button.  The Add Proxy window will appear.
6. Enter the IP address or a host name for one of the ZonePRO devices on the remote net-

work and click OK.

7. Press the Finish button to close the properties window.
8. Select Go Online from the Network menu.   After a moment you will see your devices

appear in the window.

If  the  ZonePRO  Designer  software  can  not  establish  a  connection  with  the  proxy  you  will
receive a failure message after about one minute of trying to connect.

Proxy can be used to allow remote access to monitor and make minor changes to any ZonePRO
1260 or 1261 that is accessible from the internet.  There are some things that can not be done
over a proxy connection.   For example, it is not possible for you to change the IP or node
addresses over a proxy connection.    Proxy is not intended for initial setup of any ZonePRO
1260/1261 it can only be used for remote monitoring and maintenance. 

A.6.6 Virtual Private Networks (VPN)

Virtual private networks (VPN) provide an encrypted connection (or tunnel) between networks
or between a network and a user over a public network (such as the Internet). Instead of using
a dedicated, real-world connection such as leased line, a VPN uses virtual connections through
the public network.  The advantage to a VPN is that your computer can be virtually connected
to a local network even though it is physically anywhere in the world where you have an inter-
net connection.  This can also be done in a safe manner not compromising your local network’s
security.  If you would like to manage your ZonePRO 1260 / 1261s remotely you should create
a secure VPN connection.

There are many solutions on the market today that provide VPN access.  These products offer
different features, methods of VPN, complexity of setup and maintenance, as well as varying
levels of security.  It is beyond the scope of this manual to recommend a VPN solution that will
best suit the needs of your network, although you will need a VPN that is capable of passing
