Billion 800VGT Router
Universal Plug and Play (UPnP)
This protocol is used to enable simple and robust connectivity among
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,
IP phone and others.
SOHO Firewall Security with DoS and SPI
Along with the
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.
