(Wireless) ADSL VPN Firewall Router with 3DES Accelerator
Chapter 1: Introduction 1
Chapter 1: Introduction
Introduction to your (Wireless) ADSL Router
Welcome to the (Wireless) ADSL VPN Firewall Router. Your router is an “all-in-one” unit,
combining an ADSL modem, ADSL router and Ethernet network switch, providing everything
you need to get the machines on your network connected to the Internet over your ADSL
broadband connection. With features such as an ADSL Quick-Start wizard and DHCP Server,
you can be online in no time at all and with a minimum of fuss and configuration, catering for
first-time users to the guru requiring advanced features and control over their Internet
connection and network.
Features
ADSL Multi-Mode Standard
Supports downstream transmission rates of up to 8Mbps and upstream transmission rates of
up to 1024Kbps. It also supports rate management that allows ADSL subscribers to select
an Internet access speed suiting their needs and budgets. It is compliant with Multi-Mode
standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2)). The Annex A and B are
supported in different H/W platforms.
Wireless Ethernet 802.11b ((Wireless) ADSL Router Only)
Provides a wireless Ethernet 802.11b access point for extending the communication
media to WLAN.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built in with automatic switching between MDI
and MDI-X for 10Base-T and 100Base-TX ports. An Ethernet straight or cross-over cable
can be used directly for auto detection.
Multi-Protocol to Establish A Connection
Supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) and IPoA
(RFC1577) to establish a connection with the ISP. The product also supports VC-based
and LLC-based multiplexing.
Quick Installation Wizard
Supports a WEB GUI page to install this device quickly. With this wizard, end users can
enter the information easily which they get from their ISP, then surf the Internet
immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal

(Wireless) ADSL VPN Firewall Router with 3DES Accelerator
Chapter 1: Introduction 2
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors. It makes network simple and affordable for users.
UPnP architecture leverages TCP/IP and the Web to enable seamless proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
Allows multi-users to access outside resources such as the Internet simultaneously with
one IP address/one Internet access account. Many application layer gateway (ALG) are
supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping,
NetMeeting, IP phone and others.
Firewall
Supports SOHO firewall with NAT technology, automatically detects and blocks Denial of
Service (DoS) attacks. URL blocking, packet filtering and SPI (Stateful Packet Inspection)
are also supported. The hacker’s attack will be recorded associated with timestamp in the
security logging area. More firewall functions will always be implemented through updated
firmware releases.
Domain Name System (DNS) relay
Provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) and IP address. When a local machine sets its DNS server with this
router’s IP address, every DNS conversion request packet from the PC to this router will be
forwarded to the real DNS in the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. For example, to use the service, you must
first apply for an account from a DDNS service like http://www.dyndns.org/. More than 5
DDNS servers are supported.
Virtual Private Network (VPN)
Allows user to make a tunnel with a remote site directly to secure the data transmission
among the connection. User can use embedded PPTP and L2TP client/server, IKE and
IPSec which are supported by this router to make a VPN connection or users can run the
PPTP client in PC and the router already provides IPSec and PPTP pass through function
to establish a VPN connection if the user likes to run the PPTP client in his local computer.
Virtual Server (“port forwarding”)
Users can specify some services to be visible from outside users. The router can detect
incoming service requests and forward either a single port or a range of ports to the
specific local computer to handle it. For example, a user can assign a PC in the LAN
acting as a WEB server inside and expose it to the outside network. Outside users can
browse inside web servers directly while it is protected by NAT. A DMZ host setting is also
provided to a local computer exposed to the outside network, Internet.
Rich Packet Filtering
Not only filters the packet based on IP address, but also based on Port numbers. It will
filter packets from and to the Internet, and also provides a higher level of security control.
Dynamic Host Configuration Protocol (DHCP) client and server

(Wireless) ADSL VPN Firewall Router with 3DES Accelerator
Chapter 1: Introduction 3
In the WAN site, the DHCP client can get an IP address from the Internet Service Provider
(ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP
addresses and distribute them including IP address, subnet mask as well as DNS IP
address to local computers. It provides an easy way to manage the local IP network.
Static and RIP1/2 Routing
Supports an easy static routing table or RIP1/2 routing protocol to support routing
capability.
Simple Network Management Protocol (SNMP)
It is an easy way to remotely manage the router via SNMP.
Web based GUI
Supports web based GUI for configuration and management. It is user-friendly and comes
with on-line help. It also supports remote management capability for remote users to
configure and manage this product.
Firmware Upgradeable
Device can be upgraded to the latest firmware through the WEB based GUI.
Rich management interfaces
Supports flexible management interfaces with local console port, LAN port, and WAN port.
Users can use terminal applications through the console port to configure and manage the
device, or Telnet, WEB GUI, and SNMP through LAN or WAN ports to configure and
manage the device.
