Security Features
You will be glad to learn about the security elements we have put in place to better
protect your data and privacy.
64/128-bit WEP encryption support for wireless security
The Compex NetPassage WPE54G uses a private key encryption known as Wired Equivalent
Privacy protocol with key lengths of either 64-bit or 128-bit, to protect data communication
in your wireless net work can.
802.1x Authentication
Compex supports the industry standard IEEE 802.1x authentication for enhanced security in
wireless networks. By using the existing Extensible Authentication Protocol (EAP, RFC 2284)
that works on both wired and wireless LANs for message exchange during the
authentication process, 802.1x authenticates the user with a central authority.
Built-in “NAT” firewall
As the Compex NetPassage WPE54G handles the incoming and outgoing data packet
transactions between the internal and external network, it loo ks at and validates ind ividual
packet in formation before passing it onto a client in the network. This checking provides
effective firewall protection and automatically discards rogue packets.
Internet Access Policies: Packet filtering
To complement the NAT technologies incorp orated into the Compex NetPassage WPE54G,
you can use the packet filtering features to regulate the types of Internet Access permitted
and control the transmission of TCP, UDP packets for different ports.
Wireless Pseudo VLAN
Compex’s exclusive Wireless Pseudo VLAN feature extends the security adv antages of the
Ethernet-based VLAN to wireless networks. This feature offers data privacy and protection
between individual clients in a wireless network, and is
network or in a public ‘hotspot’.

When to use which mode
The WPE54G is unique in the sense that it may operate in up to 5 different complex
modes in order to best suit any type of network applications that you might require.
We will henceforth employ the generic term AP mode when referring to the Access
Point and Gateway modes and the generic term wireless client mode to refer to the
Access Point Client, the Wireless Routing Client and the Wireless Ethernet Adapter
modes.
This section presents a brief ou tline of the different network applications that can be
accommodated through the different modes of the WPE54G.
The Access Point Mode
This is the default mode of the NetPassage WPE54G. The Access Point mode enables
you to bridge the wireless clients in your network to the wired network infrastructure.
The diagram below illustrates the WPE54G bridging a Fast Ethernet network with
Wireless 802.11b and 802.11g networks.

Getting to kno w your prod uct
The Gateway Mode
Or more simply put: Broadband Internet sharing in a wireless network!
Since the WPE54G supports different types of broadband connections, the first step
towards a successful setup of the WPE54G as a Broadband Internet Gateway is to
identify the type of broadband Internet access you are subscribed to.
Static IP address
Use this type of connection if you have subscribed to a fixed IP address or a range of
fixed IP addresses from your Internet Service Provider.
Dynamic IP address
When powered through this type of connection, the WPE54G will request for an IP
address which will be automatically assigned to it by your Internet Service Provider.
For instance, this type of connection applies for:
- Singapore Cable Vision subscribers
- @HOME Cable Service users
Certain Internet Service Providers request for a DHCP Client ID before allocating an
IP address. In such a case, you should configure the System Identity with the DHCP
Client ID.
PPP over Ethernet (PPPoE)
Select this type of connection if you are using ADSL services in a country utilising
standard PPP over Ethernet for authentication.
For instance:
- if you are in Germany which uses T-1 connection or
- if you are using SingNet Broadband or Pacific Internet Broadband in
Singapore.
Singapore ADSL (Ethernet 512K)
All other ADSL subscribers in Singapore including SingTel Magix SuperSurf users
should opt for this type of connection.

Chapter 2
Getting to kno w your prod uct
Australia BPA Cable
This type of connection is especially customised for Big Pond Cable Internet users in
Australia.
PPTP
The Point-to-Point Tunneling Protocol (PPTP) mode enables the implementation of
secure multi-protocol Virtual Private Networks (VPNs) through public networks.
The Wireless Routing Client Mode
When set up in the Wireless Routing Client mode, the WPE54G connects your
network on client site to any Internet connection while ensuring communication
among the clients on your network as well. The Routing Client would thus act as a
secure Internet gateway on your LAN, not only protecting the LAN against outside
intruders but also filtering internal users’ access to the Internet, if so configured.
An application of this mode could be for the WPE54G to act as a wireless client
bridge for broadband routing. In such a case, the Ethernet port of the wireless routing
client would be used for ad hoc connection with other devices on the network while
access to the Internet would be achieved through wireless communication with
another access point, which connects to the Internet via an ADSL/Cable modem.
The Wireless Ethernet Adapter Mode
This mode is intended for usage by Internet Service Providers. It is conceptually close
to the Access Point Client mode in that the W PE54G used in this mode, is able to
communicate wirelessly with another access point to perform transparent bridging
between two networks.
The difference lies in that the function of a network adapter is to interface a computer
to a network. Thus, the Wireless Ethernet Adapter connects with a single wired
workstation only. This characteristic implies more leeway for the user to set up more
explicit parameters for better control over communication to and from the workstation.

System Identity
If your network operates with several Compex NetPassage WPE54G, you would find
it useful to have a means of identifying each individual device.
In certain cases, your Internet Service Provider might request for a System Name
before allowing you to access the Internet. This System Name also serves as a DHCP
Client ID during negotiations with the DHCP Server for dynamic IP address
allocation.
You can define the System Identity of the WPE54G to be also utilised as System
Name or as DHCP Client ID.

Chapter 6: Advanced Configuration
Management Port Setup
This section addresses the Advanced DHCP Server Options made available to the
network administrator.
The built-in DHCP server in the WPE54G facilitates the IP address allocation
management of your network by automatically and dynamically allocating addresses
to the devices connected to the network.
However, you may in addition, require DHCP server reservations for specific IP and
MAC addresses. For instance, if you set up a publicly accessible FTP/HTTP server
that resides within a private LAN, while that server would require a fixed IP address,
you would still want the DHCP server to dynamically allocate IP addresses to the rest
of the PCs on the private LAN.
The ability to make IP reservations enables you to assign a fixed IP address to your
FTP/HTTP server and subsequently inform the DHCP server to exclude that specific
address from the pool of addresses it draws on for its dynamic address allocation.
The next diagram illustrates fixed and dynamic IP addressing using the WPE54G.

WEP Encryption
WEP Encryption
Wired Equivalent Privacy (WEP) is a security protocol for wireless local area
networks (WLANs). It aims to provide security by encrypting data over radio waves
so that it is protected while being transmitted from one end point to another.
Both the access point and the client device use the same WEP key to encrypt and
decrypt messages. WEP keys encrypt both unicast and multicast messages within the
network.
The WPE54G supports both 64-bit as well as 128-bit WEP encryption keys in both
alphanumeric as well as hexadecimal format.

The WAN setup is only operational when the WPE54G is configured in either the
Gateway mode or the Wireless Routing Client mode.
If your ISP requires your Ethernet MAC address to be authenticated before assigning
an IP address to the WAN interface, the MAC address of the Ethernet adapter
originally installed on your PC with the cable modem will need to be cloned to the
WPE54G. That PC must be used to log on to the WPE54G to change its Ethernet
MAC address to that of the Ethernet card.

Wireless Setup - The Wireless Distributed System (WDS)
The Wireless Distribution System (WDS) feature allows you to indefinitely extend the
range of your network infrastructure by simply connecting access points wirelessly.
The inherent flexibility of the WDS allows the setup of numerous advanced
configurations for your network infrastructure -- each having specific operational
benefits. We shall list two popular WDS network configurations which can be set up
using the WPE54G:
Star Configuration Infrastructure Network
In a star configuration WDS, links are established between one root (central)
WPE54G which acts as an access point and several other (satellite) WPE54G’s. The
satellite WPE54G’s are positioned to cover an area beyond that covered by the single
root device.
