Introduction
1.1 An Overview of BIPAC-741 GE V2.0
The BIPAC-741 GE V2.0 router provides a high-speed ADSL port, a 4-port 10/100M Base-T
Ethernet switch for high-speed Internet browsing. It can support downstream transmission rates
of up to 8Mbps and upstream transmission rates of up to 1024Kbps. It also supports rate
management that allows ADSL subscribers to select an Internet access speed suiting their needs
and budgets. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1);
G.lite (G992.2).
The product supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516), and IPoA
(RFC1577) to establish a connection with ISP. Besides, an embedded PPTP client and PPTP
server are supported to establish a VPN tunnel with a remote PPTP device. The product also
supports VC-based and LLC-based multiplexing.
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.
This product also serves as an Internet firewall, protecting your network from being accessed by
outside users. Not only provides the natural firewall function (Network Address Translation,
NAT), it also provides rich firewall features to secure a 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. First, 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, a user can open some specific ports for outside users to access
internal services in the network. Finally it can also detect and block many Hacker Patterns and
not allow hackers into your network.
Integrated DHCP services, client and server, allows 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 and reboot. Each time a local
machine is powered up; the router will recognize it and assign an IP address to instantly connect
it to the LAN.
For advanced users, The 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

Billion BIPAC-741 GE V2.0 ADSL Firewall Router
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.

Chapter 1 Introduction
Firewall: Supports SOHO firewall with NAT technology. Automatically detects and blocks the
Denial of Service (DoS) attack. The URL-blocking, packet filtering and SPI are also supported.
The hacker’s attack will be recorded associated with timestamp in the security logging area.
More firewall features will be added continually, please visit our web site to download latest
firmware.
Domain Name System (DNS) relay: provides an easy way to map the domain name (a friendly
server with this router’s IP address, then every DNS conversion requests packet from the PC to
this router will be forwarded to the real DNS in the outside network. After the router gets the
reply, then forwards it back to the PC.
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 an account from this free Web server
Virtual Private Network (VPN): Allows a user to make a tunnel with a remote site directly to
secure the data transmission among the connection. Users can use embedded PPTP
client/server and IPSec supported by this router to make a VPN tunnel or the user 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.
PPP over Ethernet (PPPoE): Provide embedded PPPoE client function to establish a
connection. Users can get greater access speed without changing the operation concept, sharing
the same ISP account and paying for one access account. No PPPoE client software is required
for the local computer. The Always ON, Dial On Demand and auto disconnection (Idle Timer)
functions are provided too.
Virtual Server: Users can specify some services to be visible from outside users. The router can
detect incoming service request and forward it to the specific local computer to handle it. For
example, users can assign a PC in a LAN acting as a WEB server inside and expose it to the
outside network. Outside users can browse an inside web server 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.
Dynamic Host Control Protocol (DHCP) client and server: In the WAN site, the DHCP client
can get an IP address from the Internet Server Provider (ISP) automatically. In the LAN site, the
DHCP server can allocate up to 253 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 table or RIP1/2 routing protocol to support
routing capability.
SNTP: An easy way to get the network real time information from an SNTP server.

Chapter 3 Configuration
Port # Connection Type: Five options to choose from: auto, 10M half-duplex, 10M full-duplex,
100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility problems
with legacy Ethernet devices. You can configure different types to solve the compatibility
issues.
Port # Rate Limit: When it is enabled, enter a rate value that is configured as multiple of
32kbps. This function limits the inbound and outbound Ethernet throughput around the value
that you specified.
TOS, Type of Services, is the 2nd octet of IP packet. The bits 6-7 of this octet are reserved and
bit 0-5 are used to specify the priority of the packet.
IPv4 TOS priority Control: This feature uses bits 0-5 to classify the packets’ priority. If the
packet is in high priority, it will flow first and will not be constrained by the Rate Limit.
Therefore, when this feature is enabled, the embedded Ethernet switch IC will check the 2nd octet
of each IP packet. If the value in the TOS field matches in the checked values in the table (0 to
63), this packet will treat it as high priority.
When you click DHCP Server, you get the following figure. You can disable or enable the
DHCP server or enable the DHCP relay functions.
If you check Disabled and click Next, then click Apply. The DHCP server function is disabled.
Each PC in the LAN should assign a fixed IP address and set the PC’s gateway to the ADSL
router.
If you check DHCP Server and click Next, you can configure parameters of the DHCP server
including the IP pool (starting IP address and ending IP address), leased time for each assigned
IP address, DNS IP address, Gateway IP address. Those messages are sent to the DHCP client
when it requests an IP address from the DHCP server. Click Apply to enable this function. If
you check “Use Router as a DNS Server”, the ADSL Router will find the IP address from the
outside network automatically and forward it back to requesting PC in the LAN.

Billion BIPAC-741 GE V2.0 ADSL Firewall Router
Being a natural Internet firewall, this network router protects your network from being accessed
by outside users. When it needs to allow outside users to access internal servers, e.g. Web server,
FTP server, E-mail server or News server, this modem can act as a virtual server. You can set up
a local server with specific a port number that stands for the service, e.g. Web (80), FTP (21),
Telnet (23), SMTP (25), POP3 (110), When an incoming access request to the router for a
specified port is received, it will be forwarded to the corresponding internal server.
For example, if you set the Service Port number 80 (Web) to be mapped to the IP Address
192.168.1.2, then all the http requests from outside users will be forwarded to the local server
with IP address of 192.168.1.2. If the port is not listed as a predefined application, you need to
add it manually.
DMZ: The DMZ Host is a local computer exposed to the Internet. Therefore, an incoming
packet will be checked by the Firewall and NAT algorithms, then passed to the DMZ host when
a packet is not sent by a hacker and not limited by the virtual server list.
If you have disabled the NAT option in the WAN-ISP section, this Virtual Server
function will hence be invalid.
If the DHCP server option is enabled, you have to be very careful in assigning the
IP addresses of the virtual servers in order to avoid conflicts. The easy way is that
the IP address assigned to each virtual server should not fall into the range of IP
addresses that are to be issued by the DHCP server. You can configure the virtual
server IP address manually, but it is still in the same subnet with the router.
