Billion 800VGT Router
Universal Plug and Play (UPnP)
This protocol is used to enable simple and robust connectivity among stand-alone devices and
computers 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 applications such as Net Meeting or MSN Messenger seamlessly.
Network Address Translation (NAT)
This function allows multiple 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, such as web browsing, 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 LAN.
Domain Name System (DNS) Relay
This provides an easy way to map the domain name (a friendly name for users such as
www.yahoo.com) to an IP address. When a local computer has its DNS server IP address
configured to the router's IP address, every DNS conversion request packet from the Computer 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 WAN IP address to a static hostname.
To use the service, you must first apply for an account from a DDNS service like
http://www.dyndns.org/. More than 5 different DDNS services 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 at lightning speed, even under heavy load. The QoS features
are configurable by source IP address, destination IP address, protocol, or 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, or alternatively, you can simply change the priority of different types of upload data and
let the router sort out the actual speeds.
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 to act as a WEB server and expose it to
Internet users. Outside users can browse this web server directly, while it is still protected by NAT. A
DMZ host setting is also provided to completely expose a local computer the Internet.
Rich Packet Filtering
This not only filters the packet based on IP address, but also based on Port numbers. It will filter
packets to and from the Internet, and provides a higher level of security control.
