CHAPTER 1 Introduction &
Installation
This chapter introduces Neoware Firewall and describes the
installation procedure.
What is Neoware Firewall?
Neoware Firewall is a utility to assist in the configuration of IP
security policies to protect your thin client by establishing a local
firewall. This powerful utility can be used to create static ingress
and egress rules by port, protocol, source, and destination.
Neoware Firewall provides a user-friendly interface for easy con-
figuration of the firewall. It also provides a set of predefined secu-
rity rules and an export option to clone a customized configuration
to other thin clients.
Neoware Firewall & Windows Firewall
Microsoft Windows Firewall may also be included with XPe thin
clients in addition to Neoware Firewall. Note that Microsoft Win-
dows Firewall only handles inbound traffic, whereas Neoware
Firewall handles both inbound and outbound traffic.
If Microsoft Windows Firewall is included, it may be enabled by
default. The Administrator can decide whether the Windows Fire-
wall should be left turned on, or to only rely on Neoware Firewall
once it is configured and enabled. Note that Neoware Firewall does

not require the Windows Firewall, and Neoware Firewall can func-
tionally replace the Windows Firewall for incoming traffic.
Installation Procedure

dure applies. This snap-in is available on the Neoware web site.
After installation you will find a shortcut in the Start menu named
Neoware Firewall Configuration Utility.

CHAPTER 2 Configuring Neoware
Firewall
This chapter describes how to configure Neoware Firewall to
provide the level of protection required for your thin client.
Introduction
Neoware Firewall is disabled by default. If you are using ezUpdate
and have configured your FTP server to use passive data connec-
tions, you will need to configure Neoware Firewall for passive FTP
before enabling it. Since passive FTP servers may be configured to
use a range of ports anywhere between 1024 and 65535, there is no
way of pre-configuring these ports in Neoware Firewall without
making the firewall essentially ineffective. Enabling Neoware Fire-
wall without configuring it for passive FTP will make ezUpdate
fail for those networks using passive FTP.

Currently Defined Firewall Filters 5
Currently Defined Firewall Filters
The main dialog of the Neoware Firewall configuration utility shows
a list of all the currently defined firewall filters, together with some
descriptive information.
Neoware Firewall provides a default set of predefined firewall filters
so that you can use the firewall immediately. For a list of all the pre-
defined filters and their functions, refer to the appendix “Default
Neoware Firewall Rules” on page 15
The list of firewall filters includes the following information:
Assign A check box indicating the status of the filter
(assigned or unassigned).
Filter Name The name of the firewall filter.
Action Indicates whether the filter Blocks or Permits data
flow.
Description Provides a description of what the filter does.
