Introduction

This Chapter provides an overview of VRT-401's features and capabilities.

Congratulations on the purchase of your new VRT-401. VRT-401 is a multi-function device providing the following services:

• Shared Broadband Internet Access for all LAN users.

• 4-Port Switching Hub for 10BaseT or 100BaseT connections.

Figure 1: VRT-401

VRT-401 Features

VRT-401 incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.

Internet Access Features

• Shared Internet Access. All users on LAN side can access the Internet

through VRT-401, 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. VRT-401 has a 10/100BaseT Ethernet port

for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported. Furthermore, SingTel RAS and Big Pond (Australia) login are supported as well.

• 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, VRT-

401 supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address.

VRT-401 User Manual

Advanced Internet Functions

• Communication Applications. Support for Internet communication applica-

tions, 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 connec-

tions 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.

• DMZ. 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 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. VRT-401 incorporates a 4-port 10/100BaseT switch,

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. VRT-401 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 VRT-401’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. VRT-401 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 VRT-401. UPnP is by supported by Windows ME, XP, or later.

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 loca-

Introduction

tion and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - VRT-401.

• 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. VRT-401 incorporates protection against DoS attacks to secure your network.

• Rule-based Policy Firewall. To provide additional protection against mali-

cious packets, you can define your own firewall rules. This can also be used to control the Internet services available to LAN users.

VPN Features

• IPSec.. Support for IPSec standards, including IKE and certificates.

• 100 Tunnels. Up to 100 VPN tunnels can be created.

• High performance. High performance encryption engine maintains high

throughput even when using 3DES.

Connect the supplied power adapter here.

Chapter 2

Installation

This Chapter covers the physical installation of VRT-401.

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 VRT-401. Ensure VRT-401 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 VRT-401. Both 10BaseT and 100BaseT connections can be used simultaneously.

• If required, you can connect any LAN port to another Hub. Any LAN port on VRT401 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.

Installation

• If desired, connect the DMZ port to a standard port on a Hub. PCs connected to this hub will also gain Internet access, but will NOT be able to access the rest of the LAN.

3. Connect WAN Cable

Connect the DSL or Cable modem to the WAN port on VRT-401. 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 VRT-401 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 fire- wall 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.

Chapter 9: Other Features and Settings

Configuration Program

VRT-401 contains an HTTP server. This enables you to connect to it, and configure it, using your Web Browser. Your Browser must support JavaScript. The configuration program has been tested on the following browsers:

• Netscape V4.08 or later

• Internet Explorer V4 or later

Preparation

Before attempting to configure VRT-401, please ensure that:

• Your PC can establish a physical connection to VRT-401. The PC and VRT-401 must be directly connected (using the switch ports on VRT-401) or on the same LAN segment.

• VRT-401 must be installed and powered ON.

• If VRT-401’s default IP Address (192.168.0.1) is already used by another device,

the other device must be turned OFF until VRT-401 is allocated a new IP Address during configuration.

Using UPnP

If your Windows system supports UPnP, an icon for VRT-401 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 VRT-401, you can accept the desktop shortcut.

• Whether you accept the desktop shortcut or not, you can always find UPnP devices in My Network Places (previously called Network Neighborhood).

• Double - click the icon for VRT-401 (either on the Desktop, or in My Network Places) to start the configuration. Refer to the following section Config Wizard for

details of the initial configuration process.

Using your Web Browser

To establish a connection from your PC to VRT-401:

1. After installing VRT-401 in your LAN, start your PC. If your PC is already running, restart it.

VRT-401 User Manual

2. Start your WEB browser.

3. In the Address box, enter "HTTP://" and the IP Address of VRT-401, as in this example, which uses VRT-401’s default IP Address:

HTTP://192.168.0.1

If you can't connect

If VRT-401 does not respond, check the following:

• VRT-401 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 VRT-401’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 VRT-401'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 VRT-401 are on the same network segment. (If you don't have a router, this must be the case.)

4. You will be prompted for a username and password, as shown below.

IP address for VRT-401, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN.

The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which VRT-401 is attached (the same value as the PCs on that LAN segment).

• If Enabled, VRT-401 will allocate IP Addresses 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 reconfigured to treat VRT-401 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 Addresses to DHCP clients. This range also determines the number of DHCP clients supported.

See the following section for further details on using DHCP.

Setup

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.

• VRT-401 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 VRT-401’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 VRT-401’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 VRT-401’s, the following procedure is required.

1. Disable the DHCP Server feature in VRT-401. This setting is on the LAN screen.

2. Configure the DHCP Server to provide VRT-401’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 VRT-

401.

The first step is to check the PC's TCP/IP settings. VRT-401 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 default VRT-401 settings, and the default Windows TCP/IP settings, no changes need to be made.

• By default, VRT-401 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 VRT-401

• 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.

PC Configuration

Checking TCP/IP Settings - Windows 9x/ME:

1. Select Control Panel - Network. You should see a screen like the following:

Figure 8: 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.

Figure 9: IP Address (Win 95)

Ensure your TCP/IP settings are correct, as follows:

Using DHCP

To use DHCP, select the radio button Obtain an IP Address automatically. This is the default Windows setting. Using this is recommended. By default, VRT-401 will act as a DHCP Server.

Restart your PC to ensure it obtains an IP Address from VRT-401.

Using "Specify an IP Address"

If your PC is already configured, check with your network administrator before making the following changes:
