configuration of NetPassage 15-C to work with your broadband Internet account
requires you to identify the type of broadband Internet connection you have subscribed.
Refer to the following to select the correct WAN type for your broadband Internet
subscription.

i. If you have subscribed to Cable Internet of which your ISP dynamically

assigns IP address to you, please go to Section 3.2.1 titled Cable Internet
with Dynamic IP Assignment.

ii. If you have subscribed to Cable Internet of which your ISP provides you with

an IP or a range of IP addresses, please go to Section 3.2.2 titled Cable
Internet with Static IP Assignment.

iii. If you have subscribed to ADSL Internet that requires standard PPP over

Ethernet (PPPoE) for authentication, please go to Section 3.2.3 titled ADSL
Internet using PPPoE.

iv. If you are a subscriber of Singtel Magix SuperSurf in Singapore, please go to

Section 3.2.4 titled Singapore Singtel Magix SuperSurf.

v. If you are a subscriber of Big Pond Cable Internet in Australia, please go to

Section 3.2.5 titled Australia Big Pond Cable Internet.

You may find some important information concerning the broadband ISP in your country in
Appendix B of this User’s Manual.

3.2.1 Cable Internet with Dynamic IP Assignment

By default, Compex NetPassage 15-C is pre-configured to support a WAN type that
dynamically obtain an IP address from the ISP. If you have 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:

i. 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 NetPassage 15-C. Refer to the
paragraph titled Cloning MAC Address to NetPassage 15-C in this section.

ii. 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 NetPassage 15-C with a DHCP Client ID. NetPassage 15-C uses

Chapter 3 Configuring NetPassage 15-C

15

Router Identity as the DHCP Client ID to request for IP release. Refer to
Section 3.14.1 titled Setting Router Identity.

3.3 Network Address Translator (NAT)

Compex NetPassage 15-C has been designed with a Network Address Translator (NAT)
that supports Port Address Translation (PAT), sharing a single public IP address with
multiple computers in the private network by using different TCP ports for different
computers. By default, the NAT is enabled.

Chapter 3 Configuring NetPassage 15-C

21

CAUTION

Disabling the NAT will cause your computers not being able to share the
broadband Internet service. DO NOT disable the NAT unless you are
certain on what you are doing.

Due to the translation, the computers behind the NAT are not reachable from the
Internet. However, with the support of Virtual Server, you may host the Internet servers
behind the NAT based on Port Forwarding or IP Forwarding.

3.3.1 Introduction to Virtual Servers

Compex NetPassage 15-C supports two types of Virtual Server, one based on Port
Forwarding and the other based on IP Forwarding, where IP Forwarding option is only
available when the WAN interface of NetPassage 15-C 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 NetPassage 15-C’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 3.3.1-1.

Figure 3.3.1-1 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
NetPassage 15-C, 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.

Figure 3.3.1-1
Virtual Server based
on Port Forwarding

Chapter 3 Configuring NetPassage 15-C

22

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 3.3.1-2.

Figure 3.3.1-2 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.

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 the NetPassage
15-C will direct all the unresolved Internet requests to.

For example, if the WAN interface of NetPassage 15-C 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 Configuring Routing Protocol

Compex NetPassage 15-C allows the network administrator to add a static routing entry
into the routing table. Other than the default gateway to the Internet, NetPassage 15-C
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 NetPassage 15-C for broadband Internet sharing,
you DO NOT need to configure any routing information. The default
routing settings of NetPassage 15-C 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
NetPassage 15-C to re-route the packets to the remote office. Refer to Figure 3.4-1.

Figure 3.4-1
Network with multiple gateways. One to the
Internet and the other to the remote office.

In this network, the main office of subnet 192.168.168.0 contains two routers, one
connected to the broadband Internet via NetPassage 15-C (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
NetPassage 15-C’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).

Chapter 3 Configuring NetPassage 15-C

27

Alternatively, you may also activate dynamic routing protocol on NetPassage 15-C.
Compex NetPassage 15-C supports two types of routing protocol, RIP1 and RIP2.

3.4.1 Static Routing

To add a static routing entry into NetPassage 15-C’s routing table:

1. Click on the Routing

URL from the Command Menu, and the routing

configuration page will be displayed, as shown in Figure 3.4.1-1.

Figure 3.4.1-1

3. Enter the destination network address into the Destination IP Address field and
the IP address of the gateway connected to this network into the Gateway IP
Address field. For example if a gateway of IP 192.168.168.254 is connected to a
remote network 192.168.100.0, enter the Destination IP Address and Gateway IP
Address as 192.168.100.0 and 192.168.168.254 respectively.

4. Press the Apply button to add the new static routing entry into NetPassage 15-C’s
routing table

3.5 Managing NetPassage 15-C from the Internet

Compex NetPassage 15-C is integrated with an HTTP Server, enabling router
management from the private network with just a JAVA-enabled web browser. It may
also be managed via a Command Console. In addition, Compex NetPassage 15-C
supports Remote Router Management, allowing the network administrators to manage
the router from the Internet, either by a web browser or via a TELNET session.

3.5.1 Activating Remote Router Management

To activate Remote Router Management from the Internet:

1. Click on the Remote Management

URL from the Command Menu and the remote

management activation page will be displayed, as shown in Figure 3.5.1-1.

Figure 3.5.1-1

Router Management

2. Enter the desired TCP port that you wish to use for Remote Router 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 non-standard 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
NetPassage 15-C’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

.

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.

Chapter 3 Configuring NetPassage 15-C

29

For example, if your ISP has assigned 203.120.12.30 to
NetPassage 15-C’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.

3.6 Load Balancing & Fail-Over Redundancy with Parallel Broadband

Designed with the unique Parallel Broadband technology, Compex NetPassage 15-C
provides scalable Internet bandwidth with Load Balancing and Fail-Over Redundancy. If
multiple units of NetPassage 15-C 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.

3.6.1 Implementing Parallel Broadband

To implement Parallel Broadband, you need to install two or more units of NetPassage
15-C 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 NetPassage 15-Cs 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 NetPassage 15-Cs will balance the
Internet traffic among them while functioning as Fail-Over Redundancy to each other.
To activate Parallel Broadband:

1. Click on the Parallel Broadband

URL from the Command Menu and the Parallel

Broadband activation page will be displayed, as shown in Figure 3.6.1-1.

Figure 3.6-1

Broadband

2. Check the Enable radio button and press the Apply button.

NOTE

You DO NOT need to implement Parallel Broadband for Internet sharing
using one unit of NetPassage 15-C.

3.7 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. NetPassage 15-C supports Static
Address Translation that allows your notebook computer to connect to the Internet even
if it is NOT configured with the same subnet as Compex NetPassage 15-C’s.

For example, if Compex NetPassage 15-C 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 15-C 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
this function.

If your Compex NetPassage 15-C is still using the older firmware, please
go to Compex’s website at www.compex.com.sg to download the latest
firmware.

3.7.1 Enable/disable Static Address Translation

Click on the Enabled radio button followed by Apply button as shown below.

Figure 3.8-3 DNS Redirection

Now, you can easily surf the net without worries.

NOTE

If you set the IP Address of your PC to dynamic, enabling the DNS
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.

3.9 Firewall Configuration

Compex NetPassage 15-C is specially designed with firewall function to prevent
unauthorized access to or from the network. All messages entering or leaving Compex
NetPassage 15-C will pass through the firewall. It will then examine each message and
block 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 15-C uses Packet Filtering and Static inspection methods to control
the traffic flowing in and out of the network. 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.

Chapter 3 Configuring NetPassage 15-C

33

Figure 3.9-1 Configuration on Firewall

3.9.1 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.

3.9.2 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 15-C 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.

Chapter 3 Configuring NetPassage 15-C

34

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.

3.9.3 Adding Firewall Rules

If you wish to add in more rules for security purposes, simply,

1. Click on Add button and the following GUI will appear.

Click on Refresh button to update the latest information.

3.11 IP Packet Filtering

Compex NetPassage 15-C 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 PING the ISP gateway IP address. However, I cannot surf the Internet.

If you have not configured the DHCP server to configure the DNS information of the
computers in the network, you need to manually configure the DNS entry on every
computer. Without the DNS server, your will not be able to resolve domain name (eg

www.compex.com.sg

) into IP address. Refer to Section 2.2 on how to configure for

DNS server on the computer.

D.5 I am using Cable Internet and have tried to configure NetPassage 15-C to work

with it. I just couldn’t get the ISP to release an IP to me. When I connected my
computer directly to the Cable modem, I am able to surf the Internet.

Your ISP has probably logged the MAC address of your computer. You should clone the

MAC address of your computer to NetPassage 15-C. Refer to paragraph titled Cloning

MAC Address to NetPassage 15-C under Section 3.2

D.6 I have forgotten the IP address and the log in password. Is there any possibility to

reset NetPassage 15-C to factory’s default.
