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.

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.

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.

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.

(BM) in BR-6641 is separated by the direction of traffic flow – either inbound (from
WAN to LAN) or outbound (from LAN to WAN).

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.
