Configuring Your Firewall
Firewall Basics
Firewall configuration issues are our most common support call. In this chapter, we help you understand and
configure your firewall, saving you and us the trouble of a support call.
Simply put, a firewall is a device, software or hardware, which controls the flow of network traffic between your
computer and the outside world. Having a good firewall is important to prevent hackers and viruses from
getting access to your computer.
Many popular firewalls run directly on your PC; they include Microsoft Firewall, Symantec Internet Security,
ZoneAlarm, BlackICE, McAfee Personal Firewall, and many others. Each vendor provides a different interface
for network management and use different rules for protecting your computer. Many of them have built
screens and dialogs that automatically prompt you to allow and disable network access for specific programs.
Internet Filters
Internet filters are a different form of network firewall. They work to protect individuals and computers from
accessing potentially objectionable materials. These filters capture internet requests and either block or allow
them depending on whether they pass their internal tests. Like firewalls, Internet Filters can block
communications with your Luk Cameras.
LukWerks Firewall Requirements
While firewalls are useful in protecting
access to your PC, in order for you to view
cameras in your home or business and for
remote viewing, you will need to allow
firewall access to LukWerks. LukWerks
uses two networks.
First, the Werks software connects to
each of your Luk Cameras on your
Homeplug powerline network or other LAN
network.
Second, the Werks software connects to the Internet to provide you with Remote Viewing access to your video.
In communicating, two common protocols Werks uses include UPnP (Universal Plug and Play) and HTTP (on a
variety of ports).
By design, Firewalls and Internet Filters attempt to control communications on both of the internal LukWerks
network and your Internet connection. This is not a problem if you configure them correctly. Remember, it is
common to have more than one firewall installed on a PC.
You may also need to create a firewall entry to allow DHCP address assignment. This requires you to open port
67 (incoming) and 68 (outgoing) for UDP traffic on all IP addresses (i.e., broadcast messages).
Below you will find descriptions of both the automated and manual methods for configuring many popular
firewalls.
