Chapter 1
Introduction
This Chapter provides an overview of the VPN Broadband Router's features and capabilities.
Congratulations on the purchase of your new VPN Broadband Router. The VPN Broadband Router is a multi-function
device providing the following services:
Shared Broadband Internet Access for all LAN users.
VPN Gateway for IPSec, PPTP VPN connections to remote PCs or sites.
4-Port Switching Hub for 10BaseT or 100BaseT connections.
Figure 1: VPN Broadband Router
VPN Broadband Router Features
The VPN Broadband Router incorporates many advanced features, carefully designed to provide sophisticated func-
tions while being easy to use.
Internet Access Features
Shared Internet Access. All users on the LAN can access the Internet through the VPN Broadband Router,
using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This
process is called NAT (Network Address Translation).
DSL & Cable Modem Support. The VPN Broadband Router has a 100BaseT Ethernet port for connecting a
DSL or Cable Modem. All popular DSL and Cable Modems are supported. SingTel RAS and Big Pond (Australia)
login support is also included.
PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN port) connection sup-
ports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Protocol), SingTel RAS and Telstra Big Pond
(Australia), as well as "Direct Connection" type services.
Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the VPN Broadband Router supports
both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address.
Advanced Internet Functions
Communication Applications. Support for Internet communication applications, such as interactive Games,
Telephony, and Conferencing applications, which are often difficult to use when behind a Firewall, is included.
Special Internet Applications. Applications which use non-standard connections or port numbers are normal-
ly blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications
to be used normally.
Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup
is quick and easy.

VPN Broadband Router User Manual
2
Multi-DMZ. For each WAN (Internet) IP address allocated to you, one (1) PC on your local LAN can be confi-
gured to allow unrestricted 2-way communication with Servers or individual users on the Internet. This provides the
ability to run programs which are incompatible with Firewalls.
URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
Internet Access Log. See which Internet connections have been made.
VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and
IPSec are transparently supported - no configuration is required.
LAN Features
4-Port Switching Hub. The VPN Broadband Router incorporates a 4-port 10/100BaseT switching hub, making
it easy to create or extend your LAN.
DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other
devices upon request. The VPN Broadband Router can act as a DHCP Server for devices on your local LAN and
WLAN.
Multi Segment LAN Support. LANs containing one or more segments are supported; via the VPN Broadband
Router's RIP (Routing Information Protocol) support and built-in static routing table.
Configuration & Management
Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration.
Remote Management. The VPN Broadband Router can be managed from any PC on your LAN. And, if the
Internet connection exists, it can also (optionally) be configured via the Internet.
UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and configuration of the VPN
Broadband Router. UPnP is by supported by Windows ME, XP, or later.
Configuration File Backup & Restore. You can backup (download) the VPN Broadband Router's configura-
tion file to your PC, and restore (upload) a previously-saved configuration file to the VPN Broadband Router.
Security Features
Password - protected Configuration. Optional password protection is provided to prevent unauthorized
users from modifying the configuration data and settings.
NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all
LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the exter-
nal viewpoint, there is no network, only a single device - the VPN Broadband Router.
Stateful Inspection Firewall. All incoming data packets are monitored and all incoming server requests are
filtered, thus protecting your network from malicious attacks from external sources.
Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with
invalid packets and connection requests, using so much bandwidth and so many resources that Internet access
becomes unavailable. The VPN Broadband Router incorporates protection against DoS attacks.
Rule-based Policy Firewall. To provide additional protection against malicious packets, you can define your
own firewall rules. This can also be used to control the Internet services available to LAN users.
IPSec VPN Gateway Features
IPSec. Support for IPSec standards, including IKE and certificates.
10 Tunnels. Up to 10 VPN tunnels can be created.
High performance. High performance encryption engine maintains high throughput even when using 3DES.
Microsoft VPN Gateway Support
PPTP Server. The VPN Broadband Router emulates a Microsoft PPTP VPN Server, allowing clients to use the
Microsoft VPN client provided in Windows.
Windows Client Support. Remote users can use the Microsoft VPN client (VPN Adapter) provided in recent
versions of Windows.
Easy Setup. For both the Administrator and remote users, the Microsoft VPN is much easier to configure than
IPSec VPN.

ment.
The VPN Broadband Router must be installed and powered ON.
If the VPN Broadband Router's default IP Address (192.168.0.1) is already used by another device, the other
device must be turned OFF until the VPN Broadband Router is allocated a new IP Address during configuration.
Using UPnP
If your Windows system supports UPnP, an icon for the VPN Broadband Router will appear in the system tray, notifying
you that a new network device has been found, and offering to create a new desktop shortcut to the newly-discovered
device.
Unless you intend to change the IP Address of the VPN Broadband Router, you can accept the desktop shortcut.
Whether you accept the desktop shortcut or not, you can always find UPnP devices in My Network Places (pre-
viously called Network Neighborhood).
Double - click the icon for the VPN Broadband Router (either on the Desktop, or in My Network Places) to start the
configuration. Refer to the following section Setup Wizard for details of the initial configuration process.
Using your Web Browser

segment to which the VPN Broadband Router is attached (the
same value as the PCs on that LAN segment).
DHCP Server
If Enabled, the VPN Broadband Router will allocate IP Ad-
dresses to PCs (DHCP clients) on your LAN when they start
up. The default (and recommended) value is Enabled.
If you are already using a DHCP Server, this setting must be
Disabled, and the existing DHCP server must be re-
configured to treat the VPN Broadband Router as the default
Gateway. See the following section for further details.
The Start IP Address and Finish IP Address fields set the
values used by the DHCP server when allocating IP Ad-
dresses to DHCP clients. This range also determines the
number of DHCP clients supported.

DHCP
What DHCP Does
A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device)
upon request.
The client request is made when the client device starts up (boots).
The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.
The VPN Broadband Router can act as a DHCP server.
Windows 98SE/ME and other non-Server versions of Windows will act as a DHCP client. This is the default Win-
dows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address
automatically instead of "DHCP Client".
You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other
Routers, this means there must only be one (1) DHCP Server on your LAN.)
Using the VPN Broadband Router's DHCP Server
This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can:
Enable or Disable the VPN Broadband Router's DHCP Server function.
Set the range of IP Addresses allocated to PCs by the DHCP Server function.
You can assign Fixed IP Addresses to some devices
while using DHCP, provided that the Fixed IP Addresses
are NOT within the range used by the DHCP Server.
Using another DHCP Server
You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the
VPN Broadband Router's, the following procedure is required.
1. Disable the DHCP Server feature in the VPN Broadband Router. This setting is on the LAN screen.
2. Configure the DHCP Server to provide the VPN Broadband Router's IP Address as the Default Gateway.
To Configure your PCs to use DHCP
This is the default setting for TCP/IP under Windows 98SE/ME.
See Chapter 4 - Client Configuration for the procedure to check these settings.
