1.3 BR-6641 Web-based UI Overview  
After logging in, you will be able to start configuring or monitoring BR-6641  
through the Web-based UI.  
In order to help you to familiar with the basic operations, the explanations are as  
follows:  
The Web-based UI tasks are grouped into four categories. The categories are  
located at the upper left-hand corner of Web-based UI task bar. These categories  
cover all the configuration possibilities in BR-6641. The four categories are:  
System  
Network  
Service  
Log  
In the later chapters, we will introduce the functions of these four categories. On  
the first stage,you can login as Administrator in the Web-based UI and modify the  
Administrator or Monitor password by performing the following: (1)Click System  
and select Administration on task bar, (2) enter your new Administrator password  
or Monitor password, after the system confirmation, using the new password next  
time you log in.  
What shall we do if we forget the new password?  
If you forget your administrator password, use a Terminal (VT-100 compatible) to  
establish the connection between PC RS - 232 series port and BR-6641 Console  
interface, execute system reset to default.  
Before you log into serial console, please complete following setting: Bits per

BR-6641 User Manual  
second: 9600, Data bits: 8, Parity: None, Stop bits: 8, Flow control: None. The  
serial console and Web-based UI use the same username and password pairs.  
By default, the password of “Administrator” is 1234, and the password of “Monitor”  
is 5678. If the password is changed via the Web-based UI, it will also be changed  
in the serial console. In case you lose your password, you can use the username  
“reset” and password “BR-6641_edimax” to log into serial console and reset the  
system to default.  
Open the IE browser to access the Web-based UI  
Note: Please remember the changed password , otherwise it is not possible to  
access the BR-6641 management interface.

1.4.2 BR-6641 Rule/Filter/Policy Table  
Orders of Rules/Filters/Policies  
BR-6641 provides a rule table for you to perform the tasks like system parameter  
or service policies. Often you are required to add or delete rules of your own. In  
general, when you have multiple rules in a table, BR-6641 matches these rules  
from top to bottom. That is, the rules at the top of the table are given a higher  
precedence. Thus, to achieve the outcome of your desire, the more specific rules  
should be placed on top of the less specific rules.  
You will see in this table a few icons and their meanings:  
Add a new rule below the current rule.  
Move the current rule one row down.  
Move the current rule one row up.  
Delete the current rule.

Operating Rules  
When you add a new rule, the newly added rule will be placed right below the  
current rule. Moving the rule up or down will swap positions between the upper and  
lower rules.  
Checkbox  
It is quite common that you see the following checkboxes in some tables. These  
checkboxes indicate whether certain functions are enabled or not. Ared check sign  
inside a checkbox stands for “enabled”, and an empty checkbox means “disabled”.  
For example, you can enable logging for a rule by checking its checkbox in the rule  
table.

This function allows MIS to configure how WAN link health detection is performed.  
By fine-tuning certain parameters, an MIS can adjust BR-6641 to match a  
particular network structure and/or a particular ISP.  
For WAN link health detection, BR-6641 sends out ICMP or TCP packets and  
monitors responses to determine the statuses of those links. In the WAN Link

RIP Configuration  
BR-6641 support RIP (Routing Information Protocols) for both version 1 and 2. RIP  
v1 is the basic definition while v2 has some functional enhancements. Please refer to  
IETF’s official documents for the complete definition of RIP. If your private LAN  
subnet supports RIP, you need to also enable BR-6641’s RIP function, by doing as  
follows:  
Figure 3.12 LAN Private Subnet / RIP Configuration  
If the router in LAN enable RIP v1, check the checkbox in front of RIP v1. If the router  
in LAN enable RIP v2, check the checkbox in front of RIP v2.  
BR-6641 supports the transmission of RIP packets. If the authentication is enabled  
on RIP v2, password must be entered in [Authentication Password] field. If there is no  
predefined password, just leave the field blank.  
Static Routing Subnet  
If there is static routing subnet in LAN, you need to use Static Routing Subnet to fulfil  
the configuration. Static Routing Subnet means that a router route out a subnet from  
LAN, which is not connected to the BR-6641 directly.

Chapter 4 Service  
After having set up your network environment in the previous chapter, we will now  
look into the services provided by BR-6641.  
These services can help you manage your network more efficiently and effectively.  
In figure 4.1, you can see a list of functions BR-6641 is capable of. These services  
play an important role in daily network administration. For example, Firewall protects  
your network from hacker attacks. It also improves your network security by filtering  
out unwanted service types. Routing policies can maximize the utilization of your  
network resources and assign routing paths accordingly based on the status of the  
network. QoS is another feature that you can set up to manage the traffic limit for a  
given TCP/UDP service (e.g. HTTP, FTP). This feature helps you allocate available  
bandwidth for each type of service and maximize the efficiency of your network.  
Multihoming provides a safeguard against failures in WAN links. Requests to the  
internal servers (e.g. WWW server) will be dispatched evenly on every live WAN link.  
If one of them fails, the internal servers can still be reached via other live links.

4.3 Virtual Server  
Virtual Server is a feature to make your intranet (LAN) servers available to the  
Internet (WAN). Because the private IP addresses assigned to the intranet servers  
are invisible to the external environment. If you wish to make these services  
(provided on the servers) accessible to outsiders, you must tell BR-6641 to redirect  
these external requests to the right servers in the LAN or DMZ. Whenever an  
external request arrives at BR-6641, BR-6641 will look up the Virtual Server table  
and redirect the packet right to the corresponding server in the LAN or DMZ.  
You can use this function to respond to the outside request with the server in the  
LAN or DMZ, when you don’t want the private IP address to be public.

4.4 QoS  
BR-6641 provides QoS towards both inbound and outbound traffic. It can ensure  
certain services which are allocated enough bandwidth to provide satisfactory  
quality. Because of the burst nature of voice/video/data traffic, sometimes the  
amount of traffic exceeds the speed of a link. This function is to manage the  
bandwidth so as to fine-tune your bandwidth utilization. Bandwidth Management  
(BM) in BR-6641 is separated by the direction of traffic flow – either inbound (from  
WAN to LAN) or outbound (from LAN to WAN).  
Figure 4.5 The Location of “Service/QoS” on the Menu Bar  
The setting of QoS includes two parts: Classes and Filters.  
Classes are to define the bandwidth classes that the rules are imposed on. The  
defining of the class can be according to Priority, Idle/Busy Hour.

4.7 Multihoming  
Figure 4.11 The Location of “Service / Multihoming” on the Menu Bar  
BR-6641’s auto-routing service is a trunking technology that provides load balancing  
and fault tolerance for all outbound requests. But it does not apply to inbound  
requests. Based on a unique technology called SwiftDNSTM, BR-6641 offers a  
Multihoming service for load balancing and fault tolerance for inbound requests. The  
minimum requirement for Multihoming is that you must have multiple WAN links and  
registered domain names for your publicly accessible servers. Whenever BR-6641  
receives a DNS query; it answers the DNS query with a public IP address assigned  
to one of the WAN links according to the settings of your answering policies.  
Therefore, subsequent requests to your server will be sent the public IP of the WAN  
link based on BR-6641’s previous response. You can configure your answering  
policies with a weight for each WAN link so that the public IPs returned will be  
distributed evenly by weight. If one of your WAN links fails, BR-6641 will not return  
the public IP assigned to that failed link nevertheless your publicly accessible servers

are still reachable via other live WAN links.  
In order to let your Multihoming function properly, you must make sure that the  
requirements listed below are met.  
Prerequisites for Multihoming:  
Multiple WAN links (at least two).  
Registered domain names for your publicly accessible servers.  
Your publicly accessible servers must be configured as virtual servers, or have public  
IP addresses.  
By default, Multihoming is switched off. To use this service, check the check box to  
the right of “Enable Multihoming” on the top of the page. There are three tables for  
configuring your Multihoming settings. The first table lets you define the global  
parameters. The second table is used to configure your domain name settings.
