1 Chapter 1: Introduction This manual contains detail instructions, on how to setup and operate the VPN Internet Gateway. The VPN Internet Gateway provides an easy and cost effective way to communicate securely over a public network, such as the Internet. You can configure the VPN Internet Gateway to automatically encrypt all data transmitted to a particular site or sites over the Internet. The VPN Internet Gateway can create a secure connection between two or more sites. The VPN Internet Gateway is equipped with: • A WAN Ethernet port (connects to any Cable/XDSL modem) • 4 LAN Ethernet ports (connect to a PC client or a Hub/switch etc.) • One asynchronous port (connects to a dial up modem or a ISDN TA) Connect any Cable/XDSL modem to the VPN Internet Gateway, to establish a high speed Internet connection. Once an Internet connection is made, you can start establishing VPN connections. Those who require a private and secure connection will find this device an easy and cost effective solution to a lease line connection. The asynchronous port can be connected to a dial-up modem or to an ISDN TA and provides you with a backup Internet connection should the Cable/xDSL connection fail. If there is no Cable/xDSL service in your area, the asynchronous port can also serve as your Internet access connection. The VPN Internet Gateway provides a total solution for those SOHO (Small Office and Home Office), SMB (Small and Medium size Businesses) and ROBO (Remote Office and Branch Office) users, who require a VPN and other sophisticated functions at a cost effective price. 2 Features z Supports Virtual Private Network (VPN) connections (IPSec) z Supports up to 8 IPSec tunnel connections z Supports VPN client software (Safenet and SSH) z Supports DES/3DES Encryption, IP Encapsulating Security Payload (ESP), Authentication (MD5/SHA-1) z Shared Internet connection via any Cable or xDSL modem z Asynchronous port for backup or dial-up Internet connection z Supports up to 253 users z Provides solid firewall protection for LAN clients/computers z Built-in high speed 4 port 10/100 switch to connect to computers or to additional switches/hubs z Provides centralization of all network address settings (DHCP) z Comprehensive device monitoring system: Device status, Device information, System Tools, Intruder Detection log and more... z Easy-to-use, Web-based setup and configuration z Dynamic DNS to have Web and other Servers behind a Dynamic IP address z Acts as a Virtual server to enable remote access to Web, FTP, and other services on your network z DMZ for full 2-way communication between your LAN and the Internet z URL filtering function z Supports the UPnP protocol z E-Mail alert when a network security breach occurs Package Contents Please inspect your package. The following items should be included: 1). One VPN Internet Gateway (the Device) 2). One Power adapter 3). One User’s Guide If any of the above items are damaged or missing, please contact your dealer immediately. 3 Minimum System Requirements z Microsoft Internet Explorer 4.0 (or later version) or Netscape Navigator 4.0 (or later version) z One computer with an installed 10Mbps, 100Mbps or 10/100Mbps Ethernet card z One external xDSL or Cable modem with an Ethernet port (RJ-45) z One Modem or ISDN TA (if a dialup connection is needed) z One RJ-45 Cable/XDSL Internet connection z TCP/IP protocol installed in your computer z UTP network Cable with a RJ-45 connector Pre-Installation Checklist Before installing the Internet Gateway, you should: z Have carefully read the entire manual. z Be familiar with the terminology and concepts of browsers. (This guide works under the assumption that you are proficient with the browsers you are using). z Have met all the hardware and software requirements. 4 The Gateway’s Rear View The diagram below shows the Internet Gateway’s rear panel and is where all the hardware connections are made. Rear View Ports Description Power (12VDC) The power port is where you connect the DC power adapter WAN The WAN 10M Ethernet port is where you connect your ADSL/Cable modem. Serial The Serial port is where you connect the 56K modem / ISDN TA Reset If you want the device to have the factory default settings, press the reset button and hold it for 5 ~ 6 seconds. This will load the factory default settings into the device. Please be careful. Do not press the reset button unless you want to clear the current configurations. Ports 1-4 There are four LAN ports on the rear panel (supports auto crossover). This is where you connect network devices, such as PCs, switches, hubs, print servers, LAN servers or other network devices. 12VDC 5 The Gateway’s Front Panel LED On the router’s front panel there are LED lights that inform you of the router’s current status. Below is an explanation of each LED and its function. LED LED Status Description LAN (1-4) Link/Act Off Green LED will NOT Light if there is no connection ON Green LED will LIGHT when a connection has been established. Blink Green LED will BLINK if packets are been transmitted or received Serial Off Green LED will NOT Light if there is no connection ON Green LED will LIGHT when a link has been established. WAN Off Green LED will NOT Light when a link has not been established. ON Green LED will LIGHT when a link has been established. 6 LED LED Status Description STATUS Blink Yellow LED will BLINK when the device is booting up or upgrading a firmware. POWER Off NO Power ON Red LED will LIGHT if the Gateway is receiving power. Hardware Installation Setup The diagram below shows how the Internet Gateway is typically setup. 7 When you setup the hardware installation please note the following. 1. Make sure that the power supply outlet voltage is compatible with the power adapters of your PCs, Cable/XDSL modem and the Internet Gateway. 2. For the Internet Gateway, only use the power adapter that comes with it. 3. Connect a network cable from your PC’s Ethernet port to one of the LAN ports…
