VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
Chapter 1: Introduction
5
Multi-Protocol to Establish a Connection
The router 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
A WEB GUI page is provided to set up the device quickly. With this wizard, end users can easily
enter the information which they get from their ISP, then surf the Internet immediately.
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices and PCs
from many different vendors. It makes networking 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 gateways (ALG) are supported,
includings web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone
and others.
SOHO Firewall Security with DoS and SPI
Along with the built-in NAT natural firewall feature, the router also provides advanced hacker
pattern-filtering protection. It can automatically detect and block Denial of Service (DoS) attacks. The
router is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed through
the firewall to the private LAN.
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.
Quality of Service (QoS)
QoS gives you full control over which types of outgoing data traffic should be given priority by the
router, ensuring important data like gaming packets, customer information, or management
information move through the router quickly, even under heavy load. The QoS features are
configurable by source IP address, destination IP address, protocol, and port. You can throttle the
speed at which different types of outgoing data pass through the router, to ensure P2P users don’t
saturate upload bandwidth, or office browsing doesn’t bring client web serving to a halt. In addition,
you can simply change the priority of different types of upload data and let the router sort out the
actual speeds.
