Billion BIPAC-8500 / 8520 SHDSL VPN Firewall Bridge / Router
Chapter 1: Introduction
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
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.
