The OX253P has a built-in switch and allows you to access the Internet by
connecting to a WiMAX wireless network.
You can configure firewall and content filtering as well as a host of other features.
The web browser-based Graphical User Interface (GUI), also known as the web
configurator, provides easy management.
See Chapter 18 on page 181 for a complete list of features for your model.
1.1.1 WiMAX Internet Access
Connect your computer or network to the OX253P for WiMAX Internet access. See
the Quick Start Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the OX253P connects to a WiMAX
base station (BS) for Internet access.
The following diagram shows a notebook computer equipped with the OX253P
connecting to the Internet through a WiMAX base station (marked BS).
Figure 1 Mobile Station and Base Station
When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network.
Use content filtering to block access to web sites with URLs containing keywords
that you specify. You can define time periods and days during which content

filtering is enabled and include or exclude particular computers on your network
from content filtering. For example, you could block access to certain web sites for
the kids.

1.3 Good Habits for Managing the Device
Do the following things regularly to make the OX253P more secure and to manage
the OX253P more effectively.
• Change the password. Use a password that’s not easy to guess and that consists
of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the OX253P becomes
unstable or even crashes. If you forget your password, you will have to reset the
OX253P to its factory default settings. If you backed up an earlier configuration
file, you would not have to totally re-configure the OX253P. You could simply
restore your last configuration.

Introducing the Web
Configurator
2.1 Overview
The web configurator is an HTML-based management interface that allows easy
device set up and management via any web browser that supports: HTML 4.0,
CSS 2.0, and JavaScript 1.5, and higher. The recommended screen resolution for
using the web configurator is 1024 by 768 pixels and 16-bit color, or higher.
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled
by default in many operating systems and web browsers.
• JavaScript (enabled by default in most web browsers).
• Java permissions (enabled by default in most web browsers).
See the Appendix C on page 217 for more information on configuring your web
browser.
2.1.1 Accessing the Web Configurator
1Make sure your OX253P hardware is properly connected (refer to the Quick Start
Guide for more information).
