Broadband VPN Router Features
The Broadband VPN Router incorporates many advanced features, carefully designed to
provide sophisticated functions while being easy to use.
Internet Access Features
• Shared Internet Access. All users on the LAN or WLAN can access the Internet
through the Broadband VPN 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 Broadband VPN 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 supports 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
•
Broadband VPN 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 normally 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.
•
Multi-DMZ. For each WAN (Internet) IP address allocated to you, one (1) PC on your
local LAN can be configured to allow unrestricted 2-way communication with Servers or
individual users on the Internet. This provides the ability to ru n 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 Broadband VPN 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 Broadband VPN 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 Broadband VPN Router 's RIP (Routing Information Protocol) support and built-in
static routing table.
DMZ Port. Used when allowing Servers on your LAN to be accessed from the Internet,
•
the DMZ port provides additional protection for both your Servers and your LAN.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for
configuration.
•
Remote Management. The Broadband VPN 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 Broadband VPN Router. UPnP is by supported by Windows ME, XP,
or later.
• Configuration File Backup & Restore. You can backup (download) the Broadband
VPN Router's configuration file to your PC, and restore (upload) a previously-saved
configuration file to the Broadband VPN Router.
Security Features
• Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
2
•
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 external viewpoint, there is no network,
only a single device - the Broadband VPN 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
Broadband VPN 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.
VPN Gateway Features
• IPSec.. Support for IPSec standards, including IKE and certificates.
70 Tunnels. Up to 70 VPN tunnels can be created.
•
High performance. High performance encryption engine maintains high throughput
•
even when using 3DES.
Introduction
Microsoft VPN Gateway Support
• PPTP Server. The Broadband VPN 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.

Chapter 2
Installation
This Chapter covers the physical installation of the Broadband VPN Router.
Requirements
• Network cables. Use standard 10/100BaseT network (UTP) cables with RJ45 connectors.
• TCP/IP protocol must be installed on all PCs.
• For Internet Access, an Internet Access account with an ISP, and either of a DSL or Cable
modem (for WAN port usage)
Procedure
Figure 4: Installation Diagram
1. Choose an Installation Site
Select a suitable place on the network to install the Broadband VPN Router.
Ensure the Broadband VPN Router and the DSL/Cable modem are powered OFF.
2. Connect LAN Cables
• Use standard LAN cables to connect PCs to the Switching Hub ports on the Broadband
VPN Router. Both 10BaseT and 100BaseT connections can be used simultaneously.
• If required, you can connect any LAN port to another Hub. Any LAN port on the
Broadband VPN Router will automatically function as an "Uplink" port when required.
Just connect any LAN port to a normal port on the other hub, using a standard LAN cable.
• If desired, connect the DMZ port to a standard port on another Hub. PCs connected this
hub will also gain Internet access, but will NOT be able to access the rest of the LAN.

Installation
3. Connect WAN Cable
Connect the DSL or Cable modem to the WAN port on the Broadband VPN Router. Use
the cable supplied with your DSL/Cable modem. If no cable was supplied, use a standard
cable.
4. Power Up
• Power on the Cable or DSL modem.
• Connect the supplied power adapter to the Broadband VPN Router and power up.
Use only the power adapter provided. Using a different one may cause hardware damage
5. Check the LEDs
• The Power LED should be ON.
• The Status LED should flash, then turn Off. If it stays on, there is a hardware error.
• For each LAN (PC) connection, the LAN Link/Act LED should be ON (provided the PC is
also ON.)
• The WAN LED should be ON.
For more information, refer to Front-mounted LEDs in Chapter 1.
Using the DMZ Port
Please note the following points regarding the DMZ port.
• The DMZ port is a normal port, not an "uplink" port.
• PCs connected to the DMZ port are on the same LAN segment as PCs connected to the
Hub ports. They must use the same IP address range.
• PCs connected to the DMZ port are NOT visible to PCs on the hub (LAN) ports. So you
cannot use Microsoft networking or other networking protocols to connect to PCs on the
DMZ.
• PCs connected to the DMZ port still share the WAN port IP address for Internet access.
Advantages of the DMZ Port
If running any Servers on your LAN, you should connect them to the DMZ port, for the
following reasons:
• Traffic passing between the DMZ and LAN passes through the firewall. The firewall will
protect your LAN if your Server is compromised and used to launch an attack on your
LAN.
• When using the Virtual Servers feature, (see Virtual Servers in Chapter 6) a firewall rule
to allow incoming traffic from the Internet (WAN) to the DMZ is automatically created. If
the Server is connected to the LAN (hub) ports, you must add the firewall rule manually.

already running, restart it.
2. Start your WEB browser.
3. In the Address box, enter "HTTP://" and the IP Address of the Broadband VPN Router, as
in this example, which uses the Broadband VPN Router 's default IP Address:
HTTP://192.168.0.1
If you can't connect
If the Broadband VPN Router does not respond, check the following:
• The Broadband VPN Router is properly installed, LAN connection is OK, and
it is powered ON. You can test the connection by using the "Ping" command:
• Open the MS-DOS window or command prompt window.
• Enter the command:
ping 192.168.0.1
If no response is received, either the connection is not working, or your
PC's IP address is not compatible with the Broadband VPN Router 's IP
Address. (See next item.)
• If your PC is using a fixed IP Address, its IP Address must be within the range
192.168.0.2 to 192.168.0.254 to be compatible with the Broadband VPN
Router 's default IP Address of 192.168.0.1. Also, the Network Mask must be
set to 255.255.255.0. See Chapter 4 - PC Configuration for details on
checking your PC's TCP/IP settings.
• Ensure that your PC and the Broadband VPN Router are on the same network
segment. (If you don't have a router, this must be the case.)

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 Broadband VPN Router can act as a DHCP server.
• Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP
client. This is the default Windows 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 Broadband VPN 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 Broadband VPN 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 Broadband VPN Router 's, the following procedure is required.
1. Disable the DHCP Server feature in the Broadband VPN Router. This setting is on the
LAN screen.
2. Configure the DHCP Server to provide the Broadband VPN 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 95/98/ME.
See Chapter 4 - Client Configuration for the procedure to check these settings.

Chapter 4
PC Configuration
This Chapter details the PC Configuration required on the local ("Internal")
LAN.

Overview
For each PC, the following may need to be configured:
• TCP/IP network settings
• Internet Access configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the Broadband
VPN Router.
The first step is to check the PC's TCP/IP settings.
The Broadband VPN Router uses the TCP/IP network protocol for all functions, so it is
essential that the TCP/IP protocol be installed and configured on each PC.
TCP/IP Settings - Overview
If using the default Broadband VPN Router settings, and the default
Windows TCP/IP settings, no changes need to be made.
• By default, the Broadband VPN Router will act as a DHCP Server, automatically
providing a suitable IP Address (and related information) to each PC when the PC boots.
• For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP
client.
If using a Fixed (specified) IP address, the following changes are
required:
• The Gateway must be set to the IP address of the Broadband VPN Router
• The DNS should be set to the address provided by your ISP.
If your LAN has a Router, the LAN Administrator must reconfigure the Router itself. Refer to Chapter 8 - Other Features and Operations for details.
19
Broadband VPN Gateway User Guide
Checking TCP/IP Settings - Windows 9x/ME:
1. Select Control Panel - Network. You should see a screen like the following:
Figure 9: Network Configuration
2. Select the TCP/IP protocol for your network card.
3. Click on the Properties button. You should then see a screen like the following.

This lists the PCs on your LAN.
• If necessary, you can add PCs manually, using the "PC
Database" option on the advanced menu.
• For each application listed above, you can choose a
destination PC.
• There is no need to "Save" after each change; you can set the
destination PC for each application, then click "Save".
Special Applications
If you use Internet applications which use non-standard connections or port numbers, you may
find that they do not function correctly because they are blocked by the Broadband VPN
Router 's firewall. In this case, you can define the application as a "Special Application".
Special Applications Screen
This screen can be reached by clicking the Special Applications button on the Advanced
Internet screen.
You can then define your Special Applications. You will need detailed information about the
application; this is normally available from the supplier of the application.

• Start - Enter the beginning of the range of port numbers used by the
application server, for data you send to it. If the application uses a
single port number, enter it in both the "Start" and "Finish" fields.
• Finish - Enter the end of the range of port numbers used by the
application server, for data you send to it. If the application uses a
single port number, enter it in both the "Start" and "Finish" fields.
Using a Special Application
• Configure the Special Applications screen as required.
• On your PC, use the application normally. Remember that only one (1) PC can use each
Special application at any time. Also, when 1 PC is finished using a particular Special
Application, there may need to be a "Time-out" before another PC can use the same
Special Application. The "Time-out" period may be up to 3 minutes.
If an application still cannot function correctly,
try using the "DMZ" feature.
Multi-DMZ
This feature is only available if your ISP has allocated you multiple Internet IP addresses.
If you have multiple Internet IP addresses, you can assign one DMZ PC for each Internet IP
address.
• The "DMZ PC" will receive all "Unknown" connections and data received for the Internet
IP address associated with it.
• All outgoing traffic from the DMZ PC will be assigned the WAN IP address associated
with it, rather than the shared IP address on the WAN port. Note that ONLY th e DMZ PC
will use the WAN (Internet) IP address you enter on this screen.
To use this feature:
• Enter an IP address allocated to you by your ISP into th e WAN IP address field.
• Select the PC to be the DMZ PC for traffic sent to this IP address.
• Enable this DMZ.
45
Broadband VPN Gateway User Guide
The "DMZ PC" is effectively outside the Firewall,
making it more vulnerable to attacks. For this reason,
you should only enable the DMZ feature when required.
URL Filter
The URL Filter allows you to block access to undesirable Web site
• To use this feature, you must define "filter strings". If the "filter string" appears in a
requested URL, the request is blocked.
• Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination"
field in the log will display the URL. Otherwise, it will display the IP Address.
• The URL Filter can be Enabled or Disabled on the Advanced Internet screen.

Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the Virtual Server feature. It allows
Internet users to connect to your Virtual Servers using a URL, rather than an IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP address, your
IP address may change whenever you connect, which makes it difficult to connect to you.
The Service works as follows:
1. You must register for the service at http://www.dyndns.org (Registration is free). Your
password will be E-mailed to you.
2. After registration, use the "Create New Host" option (at www.dyndns.org) to request your
desired Domain name.
3. Enter your data from www.dyndns.org in the Broadband VPN Router 's DDNS screen.
4. The Broadband VPN Router will then automatically ensure that your current IP Address is
recorded at http://www.dyndns.org
5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC)
using your Domain name, as shown on this screen.
Dynamic DNS Screen
Select Internet on the main menu, then Dynamic DNS, to see a screen like the following:

Broadband VPN Gateway User Guide
Virtual Servers
This feature allows you to make Servers on your LAN accessible to Internet users. Normally,
Internet users would not be able to access a server on your LAN because:
• Your Server does not have a valid external IP Address.
• Attempts to connect to devices on your LAN are blocked by the firewall in this device.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
Figure 31: Virtual Servers
IP Address seen by Internet Users
Note that, in this illustration, both Internet users are connecting to the same IP Address, but
using different protocols.
To Internet users, all virtual Servers on your LAN have the same IP Address.
This IP Address is allocated by your ISP.
This address should be static, rather than dynamic, to make it easier for Internet users to
connect to your Servers.
However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your
Virtual Servers using a URL, instead of an IP Address.
50
Advanced Features
Using the DMZ port for Virtual Servers
You should connect your Virtual Servers to the DMZ port, for the following reasons:
• Traffic passing between the DMZ and LAN passes through the firewall. The firewall will
protect your LAN if your Server is compromised and used to launch an attack on your
LAN.
• For each enabled Virtual Server, a firewall rule to allow incoming traffic from the Internet
(WAN) to the DMZ is automatically created. If the Server is connected to the LAN (hub)
ports, you must add the firewall rule manually.
Note that the DMZ port is a normal port, not an "uplink" port. If connecting to a hub, connect
to the standard port on the hub.
Virtual Servers Screen
The Virtual Servers screen is reached by the Virtual Servers link on the Internet menu. An

Defining your own Virtual Servers
If the type of Server you wish to use is not listed on the Virtual Servers screen, you can use the
Firewall Rules to allow particular incoming traffic and forward it to a specified PC (Server).
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use
the Internet IP Address (the IP Address allocated to you by your ISP).
e.g.
http://203.70.212.52
ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the Dynamic DNS feature, described in the following section, to allow
users to connect to your Virtual Servers using a URL, rather than an IP Address.

Firewall Rules
For normal operation and LAN protection, it is not necessary to use this screen.
The Firewall will always block DoS (Denial of Service) attacks. A DoS attack does not attempt
to steal data or damage your PCs, but overloads your Internet connection so you can not use it
- the service is unavailable.
As well, you can use this screen to create Firewall rules to block or allow specific traffic. But
Incorrect configuration may cause serious problems.
This feature is for advanced administrators only!
Firewall Rules Screen
Click the Firewall Rules option on the Security menu to see a screen like the following
example. This example contains two (2) rules for outgoing traffic.
Since the default rule for outgoing (LAN => WAN) traffic is
"Allow", having an "Allow" rule for LAN => WAN only makes
sense in combination with another rule.
For example, the screen below shows a rule blocking all traffic to
a MSN Game Server, followed by another rule allowing access by
a specific PC.

Chapter 7
VPN
This Chapter describes the VPN capabilities and configuration required for
common situations.

Overview
This section describes the VPN (Virtual Private Network) support provided by your
Broadband VPN Router.
A VPN (Virtual Private Network) provides a secure connection between 2 points, over an
insecure network - typically the Internet. This secure connection is called a VPN Tunnel.
There are many standards and protocols for VPNs. The standard implemented in the
Broadband VPN Router is IPSec.
IPSec
IPSec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It
works at the packet level, and authenticates and encrypts all packets traveling over the VPN
Tunnel. Thus, it does not matter what applications are used on your PC. Any application can
use the VPN like any other network connection.
IPsec VPNs exchange information through logical connections called SAs (Security
Associations). An SA is simply a definition of the protocols, algorithms and keys used
between the two VPN devices (endpoints).
Each IPsec VPN has two SAs - one in each direction. If IKE (Internet Key Exchange) is used
to generate and exchange keys, there are also SA's for the IKE connection as well as the IPsec
connection.
There are two security modes possible with IPSec:
• Transport Mode - the payload (data) part of the packet is encapsulated through
encryption but the IP header remains in the clear (unchanged).
The Broadband VPN Router does NOT support Transport Mode.
• Tunnel Mode - everything is encapsulated, including the original IP header, and a new IP
header is generated. Only the new header in the clear (i.e. not protected) This system
provides enhanced security.
The Broadband VPN Router always uses Tunnel Mode.
IKE
IKE (Internet Key Exchange) is an optional, but widely used, component of IPsec. IKE
provides a method of negotiating and generating the keys and IDs required by IPSec. If using
IKE, only a single key is required to be provided during configuration. Also, IKE supports
using Certificates (provided by CAs - Certification Authorities) to authenticate the identify of
the remote user or gateway.
If IKE is NOT used, then all keys and IDs (SPIs) must be entered manually, and Certificates
can NOT be used. This is called a "Manual Key Exchange".
When using IKE, there are 2 phases to establishing the VPN tunnel:
64
VPN
• Phase I is the negotiation and establishment up of the IKE connection.
• Phase II is the negotiation and establishment up of the IPsec connection.
Because the IKE and IPsec connections are separate, they have different SAs (security
associations).
Policies
VPN configuration settings are stored in Policies.
Each policy defines:
• The address of the remote VPN endpoint
• The traffic which is allowed to use the VPN connection.
• The parameters (settings) for the IPsec SA (Security Association)
• If IKE is used, the parameters (settings) for the IKE SA (Security Association)
Generally, you will need at least one (1) VPN Policy for each remote site for which you wish
to establish VPN connections.
It is possible, and sometimes necessary, to have multiple Policies for the same remote site. In
this case, the order (sequence) of the policies is important. The policies are examined in turn,
and the first matching policy will be used.
VPN Configuration
The general rule is that each endpoint must have matching Policies, as follows:
Remote VPN address
Traffic Selector
IKE parameters
IPsec parameters
Each VPN endpoint must be configured to initiate or accept
connections to the remote VPN client or Gateway.
Usually, this requires having a fixed Internet IP address. However,
it is possible for a VPN Gateway to accept incoming connections
from a remote client where the client's IP address is not known in
advance.
This determines which outgoing traffic will cause a VPN
connection to be established, and which incoming traffic will be
accepted. Each endpoint must be configured to pass and accept the
desired traffic from the remote endpoint.
If connecting 2 LANs, this requires that:
• Each endpoint must be aware of the IP addresses used on the
other endpoint.
• The 2 LANs MUST use different IP address ranges.
If using IKE (recommended), the IKE parameters must match
(except for the SA lifetime, which can be different).
The IPsec parameters at each endpoint must match.

Common VPN Situations
VPN Pass-through
Figure 39: VPN Pass-through
Here, a PC on the LAN behind the Router/Gateway is using VPN software, but the
Router/Gateway is NOT acting as a VPN endpoint. It is only allowing the VPN connection.
• The PC software can use any VPN protocol supported by the remote VPN.
• The remote VPN Server must support client PCs which are behind a NAT router, and so
have an IP address which is not valid on the Internet.
• The Router/Gateway requires no VPN configuration, since it is not acting as a VPN
endpoint.
Client PC to VPN Gateway
Figure 40: Client PC to VPN Server
In this situation, the PC must run appropriate VPN client software in order to connect, via the
Internet, to the Broadband VPN Router. Once connected, the client PC has the same access to
LAN resources as PCs on the local LAN (unless restricted by the network administrator).
• IPsec is not the only protocol which can be used in this situation, but the Broadband VPN
Router supports IPsec ONLY.
• Windows 2000 and Windows XP include a suitable IPsec VPN client program.
Configuration of this client program for use with the Broadband VPN Router is covered
later in this document.
66
VPN
Connecting 2 LANs via VPN
Figure 41: Connecting 2 VPN Gateways
This allows two (2) LANs to be connected. PCs on each endpoint gain secure access to the
remote LAN.
• The 2 LANs MUST use different IP address ranges.
• The VPN Policies at each end determine when a VPN tunnel will be established, and what
systems on the remote LAN can be accessed once the VPN connection is established.
• It is possible to have simultaneous VPN connections to many remote sites.

• The "in" key here must match the "out" key on the remote
VPN, and the "out" key here must match the "in" key on the
remote VPN.
• Keys can be in ASCII or Hex (0..9 A..F)
• For MD5, the keys should be 32 hex/16 ASCII characters.
• For SHA-1, the keys should be 40 hex/20 ASCII characters.
SPI
• Each SPI (Security Parameter Index) must be unique.
• The "in" SPI here must match the "out" SPI on the remote
VPN, and the "out" SPI here must match the "in" SPI on the
remote VPN.
• Each SPI should be at least 3 characters.
ESP (Encapsulating Security Payload) provides security for the
payload (data) sent through the VPN tunnel. Generally, you will
want to enable both Encryption and Authentication.
• The "3DES" algorithm provides greater security than "DES",
but is slower.
• Select the key size from the drop-down list if “AES” is
selected.
• The "in" key here must match the "out" key on the remote
VPN, and the "out" key here must match the "in" key on the
remote VPN.
ESP Authentication
Generally, you should enable ESP Authentication. There is little
difference between the available algorithms. Just ensure each
endpoint use the same setting.
• The "in" key here must match the "out" key on the remote
VPN, and the "out" key here must match the "in" key on the
remote VPN.
• Keys can be in ASCII or Hex (0..9 A..F)
• For MD5, the keys should be 32 hex/16 ASCII characters.
• For SHA-1, the keys should be 40 hex/20 ASCII characters.

Aggressive Mode provides no identity protection, but is quicker.
Select the desired option:
• Initiator - Only outgoing connections will be created. Incoming
connection attempts will be rejected.
• Responder - Only incoming connections will be accepted.
Outgoing traffic which would otherwise result in a connection
will be ignored.
• Both Directions - Both incoming and outgoing connections are
allowed.
This setting does not have to match the remote VPN endpoint; the
shorter time will be used. Although measured in seconds, it is
common to use time periods of several hours, such 28,800 seconds.
Select the desired method, and ensure the remote VPN endpoint uses
the same method. The smaller bit size is slightly faster.
If enabled, PFS (Perfect Forward Security) enhances security by
changing the IPsec key at regular intervals, and ensuring that each
key has no relationship to the previous key. Thus, breaking 1 key
will not assist in breaking the next key.
This setting should match the remote endpoint.

Using Certificates
Certificates are used to authenticate users. Certificates are issued to you by various CAs
(Certification Authorities). These Certificates are called "Self Certificates".
Each CA also issues a certificate to itself. This Certificate is required in order to validate
communication with the CA. These certificates are called "Trusted Certificates."
The Certificates screen lists both the Trusted Certificate - the certificates of each CA itself and Self Certificates - the certificates issued to you.

Adding a Trusted Certificate
1. After obtaining a new Certificate from the CA, you need to upload it to the Broadband
VPN Router.
2. On the "Certificates" screen, click the "Add Trusted Certificate" button to view the Add Trusted Certificate screen, shown below.
Figure 80: Add Trusted Certificate
3. Click the "Browse" button, and locate the certificate file on your PC
4. Select the file. The name will appear in the "Certificate File" field.
5. Click "Upload" to upload the certificate file to the Broadband VPN Router.
6. Click "Back" to return to the Trusted Certificate list. The new Certificate will appear in the
list.
Adding a Self Certificate
This process is different to obtaining a Trusted Certificate. The Broadband VPN Router must
generate a request for the CA. You cannot request a Certificate directly. The correct procedure
is as follows:
1. On the "Certificates" screen, click the "Add Self Certificate" button to view the first screen
of the Add Self Certificate procedure, shown below.
Figure 81: Add Self Certificate (1)
2. Complete this screen.
Name
Enter a name which helps to identify this particular
certificate. This name is only for your reference.

Subject field.
Select the desired option.
Select the desired option. RSA is recommended.
Select the desired option. Normally, 1024 bits provides
adequate security.
3. Click "Next" to continue to the following screen.

4. Check that the data displayed in the Certificate Details section is correct. This data is used
to generate the Certificate request. If the data is not correct, click the "Back" button an d
correct the previous screen.
5. If the data is correct, copy the text in the Data to supply to CA panel to the clipboard.
6. Apply for a Certificate:
• Connect to the CA's web site.
• Start the Self Certificate request procedure.
• When prompted for the request data, copy this data (including "-----BEGIN
CERTIFICATE REQUEST-----" and "-----END CERTIFICATE REQUEST-----")
from this screen to the CA's form.
• Submit the CA's form.
• If there are no problems, the Certificate will then be issued.
7. Click "Finished" to return to the Certificate list. The new Certificate will appear in the list.
