Dual WAN
Dual WAN is a new way of getting connected to the internet which is to use two of the ADSL/EWAN
to deal with the unexpected case and balance traffic load. That is a way of improving greatly the
robustness.
Multi-Protocol to Establish a Connection
It supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation
overATM (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
It 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
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.
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
It 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.
