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,

ZoneAlert, 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

LukWerks uses two networks. First, the

Werks software connects to each of your

Luk Cameras on our Homeplug 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).
When we configure your Homeplug network, Werks sets the IP address for the USB adapter to 169.254.X.X

with a subnet mask of 255.255.0.0. Additionally, each Luk Camera picks an IP address in this same range. In

both cases, we pick random numbers for the last two elements of the IP address.
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.
Below you will find descriptions of both the automated and manual methods for configuring many popular

firewalls.
