Microsoft Fire Wall

The Windows firewall tried to auto configure itself. There may be a time when you need to set it for the ISY.


This process is in the works.


Zone Alarm

It is suggested that you set the IP address that you used above as a static IP address on your DHCP server for your "My Lighting". Otherwise, you may find yourself chasing after an allusive IP address.


  1. Disable Zone Alarm
  2. Get your ISY IP address
    • If you opened your ISY for this step close it when your done
  3. Add the ISY to your Zone Alarm Trusted Zone
    1. Open the Zone Alarm Security Suite Control Center
    2. Select "Firewall" from the left hand column, open the "Zones" tab
    3. Select "Add >>" to add a new device (My Lighting) to your Trusted Zone
    4. Type in the name of the device, "My Lighting" and it's IP address
      • An example such as 192.168.0.102 which is the address of my "My Lighting" on my network
  4. Re-enable Zone Alarm
