Introduction
1.1 An Overview of BIPAC 6600
BIPAC 6600 functions as an IEEE 802.3 Ethernet-based router. It provides four 10/100Mbps
Dual Speed Ethernet ports for connection to a home network and one 10/100Mbps Ethernet
port for a DSL Modem, Cable Modem, or other broadband access device.
The product is an integrated Internet IP sharing device with a built-in 4-port 10/100Mbps Base-T
N-Way Ethernet switch. It is the perfect solution to connect a small group of PCs to a high-
speed broadband Internet connection. Multi-users can have high-speed Internet access
simultaneously via one single IP address of the Cable/xDSL modem.
This product also serves as an Internet firewall, protecting your network from being accessed by
outside users. Not only provide the natural firewall function (Network Address Translation, NAT),
it also provides rich firewall features to secure user’s network. All incoming data packets are
monitored and filtered. Besides, it can also be configured to block internal users from
accessing to the Internet.
The product provides three levels of security support. Firstly, it masks LAN users’ IP addresses
which are invisible to outside users on the Internet, making it much more difficult for a hacker to
target a machine on your network. Secondly it can block and redirect certain ports to limit the
services that outside users can access. For example, to ensure that games and other Internet
applications will run properly, user can open some specific ports for outside users to access
internal services in network. Finally it can also detect and block many Hacker Patterns and not
allow hacker into your network.
Integrated DHCP services, client and server, allow up to 253 users to get their IP addresses
automatically on boot up from the product. Simply set local machines as a DHCP client to
accept a dynamically assigned IP address from DHCP server. Each time local machine is
powered up; BIPAC 6600 will recognize it and assign an IP address to instantly connect it to the
LAN.
For advanced users, Virtual Server function allows the product to provide limited visibility to local
machines with specific services for outside users. An ISP provided IP address can be set to the
product and then specific services can be rerouted to specific computers on the local network.
For instance, a dedicated web server can be connected to the Internet via the product and then
incoming requests for HTML that are received by the product can be rerouted to the dedicated
local web server, even though the server now has a different IP address. In this example, the
product is on the Internet and vulnerable to attacks, but the server is protected.
Virtual Server can also be used to re-task services to multiple servers. For instance, the
product can be set to allow separated FTP, Web, and Multiplayer game servers to share the
same Internet-visible IP address while still protecting the servers and LAN users from hackers.
