Introduction
1.1 An Overview of BIPAC 7100S
BIPAC 7100S ADSL Modem/Router provides a high-speed Ethernet port for high-speed Internet
browsing. It can support downstream transmission rates of up to 8Mbps and upstream transmission rates
of up to 1024Kbps. It is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1);
G.lite (G992.2); G.hs (G994.1)).
The product supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) 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. 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 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 two 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, user can
open some specific ports for outside users to access internal services in network.
Integrated DHCP (Dynamic Host Control Protocol) services, client and server, allow multiple 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 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, Virtual Service function allows the product to provide limited visibility to local
machines with specific services for outside users. An ISP (Internet Service Providers) 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.

3.4.3.4.1 Packet Filter
Packet filtering function enables you to configure your router to check specified internal/external user (IP
address) from Internet access, or you can disable specific service request (Port number) to /from
Internet. This configuration program allows you to set up different filter rules up to 6 for different users
based on their IP addresses or their network Port number. The relationship among all filters is “or”
operation, which means the device checks these different filter rules one by one, stating from the first rule.
As long as one of the rules is satisfied, the specified action will be taken.
Add: Click this button to add a new packet filter rule. After click, next figure will appear.

Active: Choose “Yes” to enable the rule, or choose “No” to disable the rule.
Packet Type: Specify the packet type (TCP, UDP, ICMP or any) that the rule will be applied to.
Select TCP if you want to scope for the connection-based application service on the remote server using
the port number. Or select UDP if you want to scope for the connectionless application service on the
remote server using the port number.
Log: Choose “Yes” if you want to generate logs when the filer rule is applied to a packet.
Action When Matched: If any packet matches this filter rule, Forward or Drop this packet.
Source IP Address: Enter the incoming or outgoing packet’s source IP address(es).
Source Port: Check the TCP or UDP packet’s source port number(s).
Destination IP Address: Enter the incoming or outgoing packet’s destination IP address(es).
Destination Port: Check the TCP or UDP packet’s destination port number(s).
If the DHCP server option is enabled, you have to be very careful in assigning the IP
addresses of filtered private IP range in order to avoid conflicts because you do not know
which PC in LAN is assigned to which IP address. The easiest and safest way is that the
filtered IP address is assigned to specific PC that is not allowed to access outside
resource such as Internet. You configure the filtered IP address manually to this PC, but it
is still in the same subnet with the router.

3.4.3.6 Virtual Server
Being a natural Internet firewall, the ADSL 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 product can act as a virtual server. You can set up a local server with
specific port number that stands for the service, e.g. Web (80), FTP (21), Telnet (23), SMTP (25), POP3
(110), DNS (53), ECHO (7), NNTP (119). When an incoming access request to the router for specified
port is received, it will be forwarded to the corresponding internal server.
For example, if you set the Public Port number 21 (FTP) to be mapped to the IP Address 192.168.1.100,
then all the ftp requests from outside users will be forwarded to the local server with IP address of
192.168.1.100.
Public Port (from) & Port (To): Enter the public port number & range you want to configure.

3.4.3.7.6 SNMP
Simple Network Management Protocol (SNMP) is an optional feature that may or may not be supported
by your ADSL Bridge/Router.
SNMP is an application layer protocol that is used for managing networks. SNMP is an optional feature
that may or may not be in the specific firmware that you are working with. There are several components
that make up the SNMP structure, including agents, network management stations (NMS), network
management protocols, and a management information base (MIB). An SNMP agent is a node that
resides on the network, typically a computer or a router. The SNMP agent is controlled and configured by
the NMS by sending SNMP messages between one another. SNMP agents are logged and identified in a
Management Information Base (MIB), in which they are identified by an object identifiers (OID).
One feature of SNMP is SNMP traps. SNMP traps are used to notify network managers of significant
events that have taken place in the network. These traps are sent to the SNMP NMS (NMS Server
located at Trap IP) through the specified ports.
SNMP System Identification: The System Name, System Contact, System Location, and System OID
are provided to identify the SNMP NMS. The System OID is the ID number placed in all Trap reports.
The System Name, System Contact, and System Location can be up to 127characters. Default value for
System OID is 1.3.6.1.4.1.4900. Read Community: This is the password to access public information.
The Read Community can be up to 127 characters. Default is “public.” Write Community: This is the
password to access private information.
The Write Community can be up to 127 characters. Default is “private.” Trap Community: This is the
password to access and view SNMP traps.
The Trap Community can be up to 127 characters. Default is “trap community.” Trap SNMP Version:
Select from Version 1 or Version 2. Default is Version 1. Trap IP: This is the IP address to which SNMP
traps are sent. There can be up to 5 different SNMP trap destination IP addresses. Trap Port: This is the
corresponding port for the SNMP trap (see Trap IP above)
