subscribed to Cable Internet of which your ISP dynamically assign an IP
address, you do not need to configure the WAN type.

However, there are exceptional cases where additional configuration is
required before an IP address is successfully obtained from the ISP:

Certain ISPs log the MAC address of the first device connected to the

broadband channel, and refuse to release an IP address unless the MAC
address matches the one in the log. If this is not a new Cable Internet
subscription and that the ISP refuses to release an IP address to you, you
may clone the “approved” MAC address to Compex NetPassage 16A.
Refer to the paragraph titled Cloning MAC Address to Compex
NetPassage 16A in this section.

Certain ISPs requires a DHCP Client ID to be authenticated before releasing

an IP address. To successfully obtain an IP address from such ISPs, you
need to configure Compex NetPassage 16A with a DHCP Client ID.
Compex NetPassage 16A uses Router Identity as the DHCP Client ID to
request for IP release. Refer to Section 3.14.1 titled Setting Router
Identity.

Port Forwarding and the other based on IP Forwarding, where IP Forwarding
option is only available when the WAN interface of Compex NetPassage 16A
has been configured with a static IP.

Virtual Server based on Port Forwarding

When Virtual Server based on Port Forwarding is implemented, Internet
requests to the IP address of Compex NetPassage 16A’s WAN interface will
be forwarded to a specific computer in the private network based on the TCP
port of the Internet request. Refer to Figure 3.3a.

Figure 3.3a Virtual Server based on Port Forwarding

Figure 3.3a shows two Virtual Servers implemented, HTTP Virtual Server and
FTP Virtual Server. To implement the Virtual Server, you need to know the
TCP port that the intended application is using.

For example, suppose that your ISP has assigned an IP address of

203.120.12.10 to your Compex NetPassage 16A, and you wish to host a web

server in your private network on a computer with an IP address of

192.168.168.10; you need to define a Virtual Server at TCP Port 80 (used by

HTTP by default) to be forwarded to 192.168.168.10. Once implemented, all
“http://203.120.12.10” requests will be forwarded to the computer with

192.168.168.10 IP address. If you wish to host another FTP server in your

private network on a computer with an IP address of 192.168.168.20; you will
then need to define a Virtual Server at TCP Port 21 (used by FTP by default)
to be forwarded to 192.168.168.20.

Chapter 3 Configuring Compex NetPassage 16A

45

Virtual Server based on IP Forwarding

If you have subscribed to a range of IP addresses from your ISP, you may also
define Virtual Servers based on IP Forwarding. This type of Virtual Server
forwards all Internet requests, regardless of the TCP port of the application, to
a computer in the private network. Refer to Figure 3.3b.

Figure 3.3b Virtual Server based on IP Forwarding

Figure 3.3b shows two Virtual Servers based on IP Forwarding. One maps the
public IP 203.120.12.11 to private IP 192.168.168.10, and the other maps the
public IP 203.120.12.12 to private IP 192.168.168.20.

3.3.2 Defining Virtual Server based on De-Militarized Zone (DMZ)

Due to the nature of Network Address Translator (NAT), the subnet behind
the NAT cannot be reached from the Internet. If you know the TCP/UDP port
of an application, such as HTTP, you can easily define a Virtual Server based
on Port Forwarding behind the NAT to support a Web Server in your private
subnet. However, if you are uncertain on the TCP/UDP port used by an
application (certain Internet games), or an application utilizes varying
TCP/UDP port, you may define a DMZ host of which Compex NetPassage
16A will direct all the unresolved Internet requests to.

For example, if the WAN interface of Compex NetPassage 16A has been
assigned an IP address of 203.120.12.20 and you have defined a DMZ host
with IP address of 192.168.168.10, all the unresolved Internet requests to

203.120.12.20 will be forwarded to 192.168.168.10, regardless of the

TCP/UDP port.

3.4 Static Address Translation (SAT)

If you are a notebook user, it is probably very often that you connect to the Internet at
your home to retrieve emails or surf the Internet. Static Address Translation function
that allows your notebook computer to connect to the Internet even if it is NOT
configured with the same subnet as Compex NetPassage 16A’s.

For example, if Compex NetPassage 16A is configured with a Class C IP of

192.168.168.1 and your notebook is configured with Class C IP of 203.120.12.47, you
may access to the broadband Internet via Compex NetPassage 16A without the need of
reconfiguring the TCP/IP of your notebook. By default, this feature is disabled.

NOTE

If you are unsure whether to activate the SAT functionality, please disable

Redirection function will not be activated.

CAUTION

You should not leave the DNS Server field in the TCP/IP Properties
window blankly or the router will not be able to assign an IP Address to
your PC. And this leads to inaccessible to the internet.

3.6 Configuring Routing Protocol

Compex NetPassage 16A allows the network administrator to add a static routing entry
into the routing table. Other than the default gateway to the Internet, Compex
NetPassage 16A may reroute the IP packets to another network. This is very useful for a
network with more than one router.

CAUTION

If you are configuring Compex NetPassage 16A for broadband Internet
sharing, you DO NOT need to configure any routing information. The
default routing settings of Compex NetPassage 16A are sufficient for
broadband Internet sharing. Improper routing configuration will cause
undesired effect.

For example, if you have two routers in the network, where one functions as an Internet
gateway and the other as a gateway to a remote office. You may define a static route in
Compex NetPassage 16A to re-route the packets to the remote office. Refer to Figure

3.6a.

Figure 3.6a Network with multiple gateways. One to the Internet and the other to the

remote office.

Chapter 3 Configuring Compex NetPassage 16A

53

In this network, the main office of subnet 192.168.168.0 contains two routers, one
connected to the broadband Internet via Compex NetPassage 16A (IP 192.168.168.1)
and the other connected to a remote office via NetPassage 11A (IP 192.168.168.254).
The remote location resides on subnet 192.168.100.0. You may add a static routing
entry into Compex NetPassage 16A’s routing table to point the gateway

192.168.168.254 to subnet 192.168.100.0. Once added, packets with destination IP
address of 192.168.100.X will be re-routed to NetPassage 11A (IP 192.168.168.254).

Alternatively, you may also activate dynamic routing protocol on Compex NetPassage
16A. Compex NetPassage 16A supports two types of routing protocol, RIP1 and RIP2.

3.6.1 Static Routing

To add a static routing entry into Compex NetPassage 16A’s routing table:

Management. Default value of “0” disables this feature.

HTTP Port

Specify the desired port for remote router management
via a web browser. If you have specified a non­standard TCP port for this field, you need to specify
the port number when you connect to the management
interface from the Internet.

For example, if your ISP has assigned 203.120.12.30 to
Compex NetPassage 16A’s WAN interface and you
have chosen to use port 2000 for HTTP remote
management, you may connect to the router
management interface by using

http://203.120.12.30:2000

.

Chapter 3 Configuring Compex NetPassage 16A

56

TELNET
Port

Specify the desired port for remote router management
via a TELNET session (Command Console). If you
have specified a non-standard TCP port for this field,
you need to specify the port number when you connect
to the command console from the Internet.

For example, if your ISP has assigned 203.120.12.30 to
Compex NetPassage 16A’s WAN interface and you
have chosen to use port 5000 for TELNET remote
console management, you may connect to the router
command console by TELNET to port 5000 of

203.120.12.30

3. Press the Save button followed by the Reboot button to complete the
process.

3.8 Load Balancing & Fail-Over Redundancy with Parallel Broadband

Designed with the unique Parallel Broadband technology, Compex NetPassage 16A
provides scalable Internet bandwidth with Load Balancing and Fail-Over Redundancy.
If multiple units of Compex NetPassage 16A are installed in the network, the Internet
traffic will be balanced across multiple broadband channels, delivering virtually a
combined aggregated bandwidth while functioning as Fail-Over Redundancy.

3.8.1 Implementing Parallel Broadband

To implement Parallel Broadband, you need to install two or more units of
Compex NetPassage 16A in the network, each connected to its broadband
Internet service account. There is no restriction on the type of broadband
Internet accounts that they are connected to. For example, if you have two
Compex NetPassage 16As in the network, you may have one connected to
Cable Internet whereas the other connected to ADSL line. Once the Parallel
Broadband is implemented, these two Compex NetPassage 16As will balance
the Internet traffic among them while functioning as Fail-Over Redundancy to
each other.

3.10 Firewall Configuration

Compex NetPassage 16A is specially designed with firewall function to prevent
unauthorized access to or from the network. All messages entering or leaving Compex
NetPassage 16A will pass through the firewall. It will then examines each message and
blocks those that do not meet the specified security criteria. The firewall can be
activated by purchasing an activation key from www.compex.com.sg

or www.cpx.com

website.

Compex NetPassage 16A uses Packet Filtering and Static inspection methods to control
the traffic flowing in and out of the network. This is much better than a normal firewall.
The packets that make it through the filters are sent to the requesting system and the rest
are discarded. Static inspection compares certain key parts of the packet to a database of
trusted information. All information that travels through the firewall is monitored for
specified defining characteristics, and the incoming information is compared to these
characteristics. If the comparison matches, the information is allowed to pass through,
otherwise, it is discarded. SPI Firewall is unlike the normal firewall that only checks the
headers of the packets, it also scrutinize the contents of the packets, ensuring the
integrity of the packets.

Figure 3.10a Configuration on Firewall

Chapter 3 Configuring Compex NetPassage 16A

61

Security level

The level of security that you have chosen (low, medium, high) will determine how
many of these threats can be stopped by firewall. The highest level of security would be
to simply block almost everything. You can restrict the traffic flows through the firewall
so that only certain information, such as email, can get through.

Log Information

Different protocols served differently for filtering purposes:

TCP (Transport Control Protocol) is used to rebuild information that travels over the
Internet.

UDP (User Datagram Protocol) is used for the information that requires no response,
such as streaming audio and video.

ICMP (Internet Control Message Protocol) is used by Compex NetPassage 16A to
exchange the information with other routers.

IGMP (Internet Group Management Protocol) is used to establish host memberships in
particular multicast groups on a single network.

If you select any of packets from the Accepted section, these received packets which
has passed the filtering rules will be displayed in the firewall log section – figure 3.11a.
This also applies to the Denied section.

3.12 IP Packet Filtering

Compex NetPassage 16A enables the users to define administrative functions based on
packet filtering rule. With IP packet filtering, you may perform Time-based Access

Management and Internet Application Filtering.

Time-based Access Management selectively allow or disallow certain computers in

the network to access to the Internet in different time frame. For example, you may
define a function to allow your children to access to the Internet only between 8:00PM
to 10:00PM.

Internet Application Filtering selectively allow/disallow certain application to connect
to the Internet. For example, if you wish to allow only web browsing in the network,
you may define a function to allow only HTTP protocol to pass through Compex
NetPassage 16A.

Chapter 4 Wireless LAN Option

Compex NetPassage 16A supports a wireless LAN option fully compliant with IEEE 802.11b.
If you wish to activate the wireless LAN option, you may install a Compex iWavePort WL11A
or WL11A+ into the PCMCIA slot of your Compex NetPassage 16A. Compex NetPassage 16A
activated with wireless LAN option distributes broadband Internet access to the Fast Ethernet &
Wireless segment, shares the resources between the Fast Ethernet network and the wireless
LAN, or functions as a LAN-to-LAN Wireless Bridge.

In compliance with IEEE 802.11b, Compex NetPassage 16A wireless LAN option utilizes the

2.4GHz ISM (Industrial, Scientific & Medical) band for up to 11Mbps & 5.5Mbps data
transmission, while backward compatible with the older 2Mbps and 1Mbps standard. To ensure
security, Compex NetPassage 16A wireless LAN option uses private encryption key for
communication over the wireless network. This technology is known as Wire Equivalent
Privacy (WEP) encryption.

4.1 Activating Compex NetPassage 16A Wireless LAN Option

To activate Compex NetPassage 16A wireless LAN option, you may install a Compex
iWavePort WL11A or WL11A+ wireless LAN card into the PCMCIA slot of Compex
NetPassage 16A.

1. Turn off the power supply of Compex NetPassage 16A.

2. Gently insert Compex iWavePort WL11A or WL11A+ into the PCMCIA slot of

Compex NetPassage 16A.

NOTE

If you are install Compex iWavePort WL11A on Compex NetPassage
16A, please ensure that the firmware version of the WL11A is 0.8.3 or
above. If the firmware of the WL11A is earlier than 0.8.3, please obtain

4.2 Operating Mode of Compex NetPassage 16A Wireless LAN Option

Compex NetPassage 16A wireless LAN option supports two operating modes, the AP
Mode and the Client Mode. You may selectively choose the operating mode based on

your application.

In AP Mode, Compex NetPassage 16A distributes the broadband Internet access to the
Fast Ethernet & wireless network, and bridge the wireless LAN to the Fast Ethernet
network. Please refer to Figure 4.2a.

Figure 4.2a Compex NetPassage 16A Wireless LAN option functions in AP Mode

4.3 Wireless Pseudo VLAN

With more deployments of IEEE 802.11b Wireless LAN in the public premises such as
the airport, university campus and fair ground, there has been a rising concern over the
privacy level that the 11Mbps wireless LAN can offer. Can you imagine yourself
surfing the Internet in the commercial hotspots and someone is peeking at your files?
WEP (Wire Equivalent Privacy) provides only privacy against unauthorized access to
the wireless network but assuming those who have already gained access to the network
to be “trusted”. While privacy remains an issue for most public Wireless LAN
implementations, the release of Wireless Pseudo VLAN, combines with WEP, brings
another level of privacy among users or groups of user.

The Wireless Pseudo VLAN defines a single Wireless LAN into multiple Virtual LANs.
Communication is only possible between wireless nodes of the same VLAN. The
Wireless Pseudo VLAN may be defined to contain a single user for each VLAN, or a
group of users per VLAN, referred as Per Node and Per Group respectively.

4.3.1 Per Node Wireless Pseudo VLAN

Per Node Pseudo VLAN, if implemented, segregates every wireless node in
its own Pseudo VLAN. Wireless clients may access to the Internet. However,
communications among wireless nodes are blocked. This type of Pseudo
VLAN is most suitable in public premises such as the airport. Users who surf
the Internet via the wireless network in the airport can be certain that their
files are not open for other users to view. WEP (Wire Equivalent Privacy) may
be defined in conjunction with Per Node Pseudo VLAN, providing security
against unauthorized access to the wireless network. Refer to Figure 4.3a.

Figure 4.3a Per Node Pseudo VLAN segregates every wireless clients in their own

VLAN

Chapter 4 Wireless LAN Option

77

4.3.2 Per Group Wireless Pseudo VLAN

In contrasting with Per Node Pseudo VLAN that supports a single user for
each VLAN with a common WEP key, Per Group Pseudo VLAN supports
multiple wireless nodes per VLAN, with different WEP key for each Pseudo
VLAN. Users from the same Pseudo VLAN may access to one another
provided that the WEP key is correct. Users from two different Pseudo
VLANs, however, cannot communicate with one another. Please refer to
Figure 4.3b.

Figure 4.3b Per Group Pseudo VLAN defines 4 Pseudo VLANs, each with its own WEP

key and contains a group of users
