With integrated 802.11n Wireless Access Point in the router, the device offers a quick and
easy access among wired network, wireless network and broadband connection (ADSL)
with single device simplicity, and as a result, mobility to the users. In addition to 300 Mbps
802.11n data rate, it also interoperates backward with existing 802.11g and 802.11b
equipment. The Wireless Protected Access (WPA) and Wireless Encryption Protocol (WEP)
supported features enhance the security level of data protection and access control via
Wireless LAN.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built-in with automatic switching between MDI
and MDI-X for 10Base-T and 100Base-TX ports, with auto detection allowing you to use
either straight or cross-over Ethernet cables.
EWAN
Besides using ADSL to get connected to the Internet, BEC 7300N offers its Ethernet port 1
as a WAN port to be used to connect to Cable Modems, VDSL and fibre optic lines. This
alternative, yet faster method to connect to the internet will provide users more flexibility to
get online.
Multi-Protocol to Establish a Connection
The router supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) to establish a
connection with an ISP. The router also supports VC-based and LLC-based multiplexing.

Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors, and it makes setting up a network simple and
affordable. UPnP architecture leverages TCP/IP and the Web to enable proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, you can seamlessly connect to Net Meeting or MSN Messenger.
Network Address Translation
Network Address Translation (NAT) allows multiple users to access outside resources such
as the Internet simultaneously with one IP address/one Internet access account. Many
application layer gateways (ALG) are supported such as web browser, ICQ, FTP, Telnet,
E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.
Firewall
NAT technology supports simple firewalls and provides options for blocking access from the
Internet, like Telnet, FTP, TFTP, WEB, SNMP and IGMP.
Domain Name System Relay
Domain Name System (DNS) relay provides an easy way to map a domain name with a
user-friendly name such as www.google.com with an IP address. When a local machine
sets its DNS server to the router’s IP address, every DNS conversion request packet from
the PC to this router is forwarded to the real DNS on the outside network.
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. To use the service, you must first apply for
an account from a DDNS service such as http://www.dyndns.org/.
PPP over Ethernet (PPPoE)
The BEC 7300N provides an embedded PPPoE client function to establish a connection.
You get greater access speed without changing the operation concept, while sharing the
same ISP account and paying for one access account. No PPPoE client software is required
for the local computer. Automatic Reconnect and Disconnect Timeout (Idle Timer) functions
are also provided.
Quality of Service (QoS)
Page 8
8
QoS gives you full control over which types of outgoing data traffic should be given priority
by the router, ensuring important data like gaming packets, customer information, or
management information move through the router ay lightning speed, even under heavy
load. The QoS features are configurable by InternalIP address, ExternalIP address,
protocol, and port. You can throttle the speed at which different types of outgoing data pass
through the router, to ensure P2P users don’t saturate upload bandwidth, or office browsing
doesn’t bring client web serving to a halt. In addition, or alternatively, you can simply change
the priority of different types of upload data and let the router sort out the actual speeds.
Virtual Server:
You can specify which services are visible to outside users. The router detects an incoming
service request and forwards it to the specific local computer for handling. For example, you
can assign a PC in a LAN to act as a Web server inside and expose it to the outside network.
Outside users can browse inside the web server directly while it is protected by NAT. A DMZ
host setting is also provided for local computers exposed to the outside Internet network.
Dynamic Host Configuration Protocol (DHCP) Client and Server
On a WAN site, the DHCP client obtains an IP address from the Internet Service Provider
(ISP) automatically. On a LAN site, the DHCP server allocates a range of client IP
addresses, including subnet masks and DNS IP addresses and distributes them to local
computers. This provides an easy way to manage the local IP network.
Rich Packet Filtering
This feature filters the packet based on IP addresses as well as Port numbers. Filtering
packets to and from the Internet provides a higher level of security control.
Web-based GUI
A web-based GUI offers easy configuration and management. It also supports remote
management capability for remote users to configure and manage this product.
Firmware Upgradeable
You can upgrade the router with the latest firmware through its web-based GUI.

Product Overview
Standards-Based Technology
The BEC 7300N Wireless Router utilizes the 802.11n standard. The IEEE 802.11n standard
is an extension of the 802.11g standard. It increases the data rate up to 300 Mbps within the
2.4GHz band, utilizing OFDM technology. This means that in most environments, within the
specified range of this device, you will be able to transfer large files quickly or even watch a
movie in MPEG format over your network without noticeable delays. This technology works
by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal
Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into
multiple smaller sub-signals that are then transmitted simultaneously at different frequencies
to the receiver. OFDM reduces the amount of crosstalk (interference) in signal
transmissions.
Installation Considerations
The BEC 7300N Wireless Router lets you access your network, using a wireless connection,
from virtually anywhere within its operating range. Keep in mind, however, that the number,
thickness and location of walls, ceilings, or other objects that the wireless signals must pass.
Keep the number of walls and ceilings between the BEC 7300N and other network devices
to a minimum - each wall or ceiling can reduce your BEC 7300N wireless product’s range
from 3-90 feet (1-30 meters.)
Position your devices so that the number of walls or ceilings is minimized. Be aware of the
direct line between network devices. Position the devices so that the signal will travel
straight through a wall or ceiling (instead of at an angle) for better reception. Building
Materials can impede the wireless signal - a solid metal door or aluminium studs may have a
negative effect on range.
Try to position wireless devices and computers with wireless adapters so that the signal
passes through drywall or open doorways and not other materials. Keep your product away
(at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme
RF (radio frequency) noise.

You can configure the BEC 7300N router through the convenient and user-friendly interface
of a web browser. Most popular operating systems such as Linux and Windows
98/NT/2000/XP/Me include a web browser as a standard application.
3.1 Before Configuration
PCs must have a properly installed Ethernet interface which connects to the router directly
or through an external repeater hub. In addition, PCs must have TCP/IP installed and
configured to obtain an IP address through a DHCP server or a fixed IP address that must be
in the same subnet as the router. The default IP address of the router is 192.168.1.254 and
the subnet mask is 255.255.255.0 (i.e. any attached PC must be in the same subnet, and
have an IP address in the range between 192.168.1.1 and 192.168.1.253). The easiest way
is to configure the PC is to obtain an IP address automatically from the router using DHCP. If
you encounter any problems accessing the router’s web interface you are advised to
uninstall any kind of software firewall on your PCs, as they can cause problems when trying
to access the 192.168.1.254 IP address of the router.
Please follow the steps below for installation on your PC’s network environment. First of all,
check your PC’s network components. The TCP/IP protocol stack and Ethernet network
adapter must be installed. If not, please refer to your Windows-related or other operating
system manuals.
Any TCP/IP capable workstation can be used to communicate with or
through the BEC 7300N. To configure other types of workstations,
please consult the manufacturer’s documentation.

5.3.1.6 DHCP Server
You can disable or enable the DHCP (Dynamic Host Configuration Protocol) server or
enable the router’s DHCP relay functions. The DHCP protocol allows your router to
dynamically assign IP addresses to PCs on your network if they are configured to obtain IP
addresses automatically.
DHCP Server Mode: Disable
To disable the router’s DHCP Server, check Disabled and then click Apply. When the
DHCP Server is disabled, you will need to manually assign a fixed IP address to each PC on
your network, and set the default gateway for each PC to the IP address of the router (the
default is 192.168.1.254).
Page 62
62
DHCP Server Mode: DHCP Server
To configure the router’s DHCP Server, check DHCP Server. You can then configure
parameters of the DHCP Server including the IP pool (starting IP address and ending IP
address to be allocated to PCs on your network), lease time for each assigned IP address
(the period of time the IP address assigned will be valid), DNS IP address and the gateway
IP address. These details are sent to the DHCP client (i.e. your PC) 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 performs the domain name lookup, finds the IP
address from the outside network automatically and forwards it back to the requesting PC in
the LAN (your Local Area Network).
DHCP Server Mode: DHCP Relay
If you check DHCP Relay and then you must enter the IP address of the DHCP server which
assigns an IP address back to the DHCP client in the LAN. Use this function only if advised
to do so by your network administrator or ISP. Click Apply to enable this function.

5.3.3 System
There are five items within the System section: Time Zone, Firmware Upgrade,
Backup/Restore, Restart, User Management and Mail Alert.
Page 74
74
5.3.3.1 Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network
Time Protocol (SNTP) to get the current time from an SNTP server outside your network.
Choose your local time zone, click Enable and click the Apply button. After a successful
connection to the Internet, the router retrieves the correct local time from the SNTP server
you have specified. If you prefer to specify an SNTP server other than those in the
drop-down list, simply enter its IP address as shown above. Your ISP may provide an SNTP
server for you to use.
Resync Period (in minutes) is the periodic interval the router waits before it resynchronizes
the router’s time with that of the specified SNTP server. To avoid unnecessarily increasing
the load on your specified SNTP server you should keep the poll interval as high as
possible – at the absolute minimum every few hours or even days.
Page 75
75
5.3.3.2 Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its
functionality. Think of your router as a dedicated computer, and the firmware as the software
it runs. Over time this software may be improved and modified. Your router allows you to
upgrade the software it runs to take advantage of these changes.
Clicking on Browse allows you to select the new firmware image file you have downloaded
to your PC. Once the correct file is selected, click Upgrade to update the firmware in your
router.
Restart Device with: To choose “Factory Default Settings” or “Current Settings” which
uses your current setting on the new firmware (it is highly advised to use Factory Default
Settings over Current Settings for a clean firmware upgrade).
New Firmware Image: Type in the location of the file you wish to upload in this field or
click Browse… to locate it.
Browse…: Click Browse… to find the file with the .afw file extension that you wish to
upload. Remember that you must decompress compressed (.zip) files before you can
upgrade from the file.
Upgrade: Click upgrade to begin the upload process. This process may take up to three
minutes.
Warning
DO NOT power down the router or interrupt the firmware upgrade while it
is still in process. Improper operation may damage the router. Please see
section 2.4 for emergency recovery procedures.
Page 76
76
5.3.3.3 Backup / Restore
These functions allow you to save and backup your router’s current settings to a file on your
PC, or to restore a previously saved backup. This is useful if you wish to experiment with
different settings, knowing that you have a backup handy in the case of any mistakes. It is
advisable to backup your router’s settings before making any significant changes to your
router’s configuration.
Press Backup to select where on your local PC to save the settings file. You may also
change the name of the file when saving if you wish to keep multiple backups.
Press Browse… to select a file from your PC to restore. You should only restore settings
files that have been generated by the Backup function, and that were created when using
the current version of the router’s firmware. Settings files saved to your PC should not
be manually edited in any way.
Select the settings files you wish to use, and press Restore to load those settings into the
router.
Page 77
77
5.3.3.4 Restart Router
Click Restart with option Current Settings to reboot your router and save the current
configuration to device.
If you wish to restart the router using the factory default settings (for example, after a
firmware upgrade or if you have saved an incorrect configuration), select Factory Default
Settings to reset to factory default settings.
5.3.3.5 User Management
In order to prevent unauthorized access to your router’s configuration interface, it requires
all users to login with a password. You can set up multiple user accounts, each with their own
password.
You are able to Edit existing users and Add new users who are able to access the device’s
configuration interface. Once you have clicked Edit on the account you want to edit, the
information of the account will be displayed above. Just go ahead and change the password.
You can change the user’s password, whether their account is active and Valid. These
options are the same when creating a user account, with the exception that once created
you cannot change the username. You cannot delete the default admin account; however
you can delete any other created accounts by clicking ticking the box under Delete and then
press the Edit/Delete button.
Page 78
78
You are strongly advised to change the password on the default “admin” account when you
receive your router, and any time you reset your configuration to Factory Defaults.
5.3.3.6 Mail Alert
Send a log via email, if WAN IP is changed or if intruders accessing your computer without
permission
5.3.4 Firewall
Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet
access from your LAN, as well as helping to prevent attacks from hackers. In addition to this,
when using NAT (Network Address Translation) the router acts as a “natural” Internet firewall,
since all PCs on your LAN use private IP addresses that cannot be directly accessed from
the Internet. See the WAN configuration section for more details on NAT.
Page 79
79
Firewall: Prevents access from outside your network.
NAT natural firewall: This 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. This natural firewall is on when the NAT function is enabled.
When using Virtual Servers (port mapping) your PCs are exposed to the
ports specified opened in your firewall packet filter settings.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules
prevent unauthorized computers or applications accessing your local network from the
Internet.
Intrusion Detection: Enable Intrusion Detection to detect, prevent, and log malicious
attacks.
MAC Filter rules: Prevents unauthorized computersaccessing the Internet.
URL Filter: Blocks PCs on your local network from unwanted websites.
Page 80
80
A detailed explanation of each of the following five items appears in the Firewall section
below: Packet Filter, MAC Address Filter, Intrusion detection, Block WAN PING and
URL Filter.
5.3.4.1 Packet Filter
Packet filtering enables you to configure your router to block specified internal/external
users (IP address) from Internet access, or you can disable specific service requests (Port
number) to /from Internet. This configuration program allows you to set up to 6 different filter
rules for different users based on their IP addresses or their network Port number. The
relationship among all filters is “or” operation, which means that the router checks these
different filter rules one by one, starting from the first rule. As long as one of the rules is
satisfied, the specified action will be taken.
Page 81
81
Rule Name: Users-define description to identify this entry. The maximum name length is
32 characters, and then can choose application that they want from listbox.
Internal IP Address / External IP Address: This is the Address-Filter used to allow or
block traffic to/from particular IP address(es). Input the range you want to filter out. If you
leave empty or 0.0.0.0, it means any IP address.
Protocol: Specify the packet type (TCP, UDP, ICMP, etc.) that the rule applies to.
Select TCP if you wish to search for the connection-based application service on the remote
server using the port number. Or select UDP if you want to search for the connectionless
application service on the remote server using the port number.
Action: If a packet matches this filter rule, Forward (allows the packets to pass) or
Drop (disallow the packets to pass) this packet.
Internal Port: This Port or Port Range defines the ports allowed to be used by the
Remote/WAN to connect to the application. Default is set from range 0 ~ 65535. It is
recommended that this option be configured by an advanced user.
External Port: This is the Port or Port Range that defines the application.
Direction: Determine whether the rule is for outgoing packets or for incoming packets.
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
Log: Choose “log” if you wish to generate logs when the filer rule is applied to a packet.
Add: Click this button to add a new packet filter rule and the added rule will appear at the
bottom table.
Edit: Check the Rule No. you wish to edit, and then click “Edit”.
Delete: Check the Rule No. you wish to delete, and then click “Delete”.

same subnet with the router.
If the DHCP server option is enabled, you must be very careful in assigning
IP addresses of a filtered private IP range to avoid conflicts because you do
Attention
not know which PC in the LAN is assigned which IP address. The easiest
and safest way is that the filtered IP address is assigned to a specific PC
that is not allowed to access an outside resource such as the Internet. You
configure the filtered IP address manually for this PC, but it stays in the
5.3.4.2 MAC Filter
A MAC (Media Access Control) address is the unique network hardware identifier for each
PC on your network’s interface (i.e. its Network Interface Card or Ethernet card). Using your
router’s MAC Address Filter function, you can configure to block specific machines from
accessing your LAN.
There are no pre-defined MAC address filter rules; you can add the filter rules to meet your
requirements.
MAC Address: Enter the MAC addresses you wish to manage.
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
Page 83
83
5.3.4.3 Intrusion Detection
Check Enable if you wish to detect intruders accessing your computer without permission.
The router automatically detects and blocks a DoS (Denial of Service) attack if a user
enables this function. This kind of attack is not to access confidential data on the network;
instead, it aims to disrupt specific equipment or the entire network. If this happens, users will
have trouble accessing the network resources.
Intrusion Detection: Check Enable if you wish to detect intruders accessing your
computer without permission.
Maximum TCP Open Handshaking Count: This is a threshold value to decide whether
a SYN Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds.
Maximum Ping Count: This is a threshold value to decide whether an ICMP Echo Storm
is occurring or not. Default value is 15 ICMP Echo Requests (PING) per second.
Maximum ICMP Count: This is a threshold to decide whether an ICMP flood is occurring
or not. Default value is 100 ICMP packets per seconds except ICMP Echo Requests (PING).
Log: Check Log if you wish to generate logs when the filer rule is applied to the Intrusion
Detection.

5.3.4.4 Block WAN PING
Check Enable if you wish to exclude outside PING requests from reaching this router.
5.3.4.5 URL Filter
URL (Uniform Resource Locator – e.g. an address in the form of http://www.example.com )
filter rules allow you to prevent users on your network from accessing particular websites
from their URL. There are no pre-defined URL filter rules; you can add filter rules to meet
your requirements.
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called “advertisement.gif”).
When enabled, your specified keywords list is checked to see if any keywords are present in
URLs accessed to determine if the connection attempt should be blocked. Note that the URL
Page 86
86
filter blocks web browser (HTTP) connection attempts using port 80 only.
For example, the URL http://www.abc.com/abcde.html would be dropped since the keyword
“abcde” occurs in the URL.
Domains Filtering: Checks the domain name in URLs accessed against your list of
domains to block or allow. If it matches, the URL request is sent (Trusted) or dropped
(Forbidden). The checking procedure is:
1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection
attempt is sent to the remote web server.
2. If not, it is checked with the forbidden list. If present, the connection attempt is dropped.
3. If the packet matches neither of the above, it is sent to the remote web server.
4. Please be note that the completed URL, “www” + domain name shall be specified. For
example to block traffic to www.google.com.au, enter “www.google” or
“www.google.com”

5.3.5 QoS (Quality of Service)
Quality of Service Introduction
If you’ve ever found your ‘net’ speed has slowed to a crawl because another family member
is using a P2P file sharing program, you’ll understand why the Quality of Service features in
the routers is such a breakthrough for home users and office users.
QoS: Keeping Your Net Connection Fast and Responsive
Configurable by internal IP address, external IP address, protocol, and port, the Quality of
Service (QoS) gives you full control over which types of outgoing data traffic should be given
priority by the router, ensuring bandwidth-consumption data like gaming packets,
latency-sensitive application like voice, or even mission critical files, move through the router
at lightning speed, even under heavy load. You can throttle the speed at which different
types of outgoing data pass through the router. In addition, you can simply change the
priority of different types of upload data and let the router sort out the actual speeds.
QoS Setup
Please choose the QoS in the Configuration item of the left window as depicted below.
After clicking the QoS item, you can Add/Edit/Delete a QoS policy. This page will show the
brief information for policies you have added or edited. This page will also display the total
available (Non-assigned) bandwidth, in percentage, can be assigned.
Application: A name that identifies an existing policy.
Page 89
89
Direction: The traffic flow direction to be controlled by the QoS policy.
There are two settings to be provided in the Router:
LAN to WAN: You want to control the traffic flow from the local network to the outside
world. e.g., you have a FTP server inside the local network and you want to have a limited
traffic rate controlled by the QoS policy. So, you need to add a policy with LAN to WAN
direction setting.
WAN to LAN: Control Traffic flow from the WAN to LAN. The connection maybe either
issued from LAN to WAN or WAN to LAN.)
Protocol: The Protocol will be controlled. For GRE protocol, there is no need to specify
the IP addresses or Application ports in this page. For other protocols, at least one value
shall be given.
ANY: No protocol type is specified.
TCP
UDP
ICMP
GRE: For PPTP VPN Connections.
DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS
byte. DSCP Marking allows users to classify traffic based on DSCP value and send packets
to next Router.
Note: To be sure the router(s) in the backbones network have the capability in executing and
checking the DSCP through-out the QoS network.

Rate Type: 2 types are provided:
Limited (Maximum): specify a limited data rate for this policy. It also is the maximal
rate for this policy. As above FTP server example, you may want to “throttle” the outgoing
FTP speed to 20% of 256K and limit to it, you may use this type.
Guaranteed (Minimum): specify a minimal data rate for this policy. For example,
you want to provide a guaranteed data rate for your outside customers to access your
internal FTP server with, say at least, 20% of your total bandwidth. You can use this type.
Then, if there is available bandwidth that is not used, it will be given to this policy by following
priority assignment.
Ratio: Assign the data ratio for this policy to be controlled. For examples, we want to only
allow 20% of the total data transfer rate for the LAN-to-WAN direction to be used for FTP
server. Then we can specify here with data ratio = 20. If you have ADSL LINE with
256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps. (For
0.9 is an estimated factor for the effective data transfer rate for a ADSL LINE from LAN to
WAN. For WAN-to-LAN, it is 0.85 to 0.8).
Page 91
91
Priority: Specify the priority for the bandwidth that is not used. For examples, you may
specify two different QoS policies for different applications. Both applications need a minimal
bandwidth and need more bandwidth, beside the assigned one, if there is any
available/non-used one available. So, you may specify which application can have higher
priority to acquire the non-used bandwidth.
High
Normal: The default is normal priority.
Low
For the sample priority assignment for different policies, it is served in a First-In-First-Out
way.
Internal IP Address: The IP address values for Local LAN machines you want to control.
(For IP packets from LAN to WAN, it is the source IP address. For IP packages from WAN to
LAN, it is the destination IP address.)
Internal Port: The Application port values for local LAN machines you want to control.
(For TCP/UDP packets from LAN to WAN, it is the source port value. For TCP/UDP packets
from WAN to LAN, it is the destination port value.)
External IP Address: The IP address values for Remote WAN machines you want to
control. (For IP packets from LAN to WAN, it is the destination IP address. For IP packages
from WAN to LAN, it is the source IP address.)
External Ports: The Application port values for remote machines you want to control.
(For TCP/UDP packets from LAN to WAN, it is the destination port value. For TCP/UDP
packets from WAN to LAN, it is the source port value.)
Time Schedule: Scheduling your prioritization policy.

5.3.6 Virtual Server
In TCP and UDP networks a port is a 16-bit number used to identify which application
program (usually a server) incoming connections should be delivered to. Some ports have
numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers
Authority), and these are referred to as “well-known ports”. Servers follow the well-known
port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from
other machines on the Internet that are outside your local network), or any application that
can accept incoming connections (e.g. Peer-to-peer/P2P software such as instant
messaging applications and P2P file-sharing applications) and are using NAT (Network
Address Translation), then you need to configure your router to forward these incoming
connection attempts using specific ports to the PC on your network running the application.
You also need to use port forwarding if you wish to host an online game server.
The reason is that when using NAT, your publicly accessible IP address is used by and
points to your router, which needs to deliver all traffic to the private IP addresses used by
your PCs. Please see the WAN configuration section of this manual for information on NAT.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the
assignment of unique parameter values for Internet protocols. Port numbers range from 0 to
65535, but only port numbers 0 to 1023 are reserved for privileged services and are
designated as “well-known ports”. The registered ports are numbered from 1024 through
49151. The remaining ports, referred to as dynamic ports, or private ports, are numbered
from 49152 through 65535.
Page 95

5.3.6.1 Port Mapping
Application: Select the service you wish to configure
Protocol: Automatic when you choose Application from listbox or select a protocol type
which you want.
External Port & Internal Port: Enter the public port number & range you wish to
configure.
Internal IP Address: Enter the IP address of a specific internal server to which requests
from the specified port is forwarded.
Add: Click to add a new virtual server rule. Click again and the next figure appears.
Edit: Check the Rule No. you wish to edit and then click “Edit/Delete”.
Delete: Check the Rule No. you wish to delete, then click “Edit/Delete”.
Since NAT acts as a “natural” Internet firewall, your router protects your network from access
by outside users, as all incoming connection attempts point to your router unless you
specifically create Virtual Server entries to forward those ports to a PC on your network.
When your router needs to allow outside users to access internal servers, e.g. a web server,
FTP server, Email server or game server, the router can act as a “virtual server”. You can set
up a local server with a specific port number for the service to use, e.g. web/HTTP (port 80),
FTP (port 21), Telnet (port 23), SMTP (port 25), or POP3 (port 110). When an incoming
access request to the router for a specified port is received, it is forwarded to the
corresponding internal server.
For example, if you set the port number 80 (Web/HTTP) to be mapped to the IP Address
192.168.1.2, then all incoming HTTP requests from outside users are forwarded to the local
server (PC) with the IP address of 192.168.1.2. If the port is not listed as a predefined
application, you need to add it manually.
Page 97
97
In addition to specifying the port number used, you also need to specify the protocol used.
The protocol is determined by the particular application. Most applications use TCP or UDP,
however you can specify other protocols using the drop-down Protocol menu. Setting the
protocol to “all” causes all incoming connection attempts using all protocols on all port
numbers to be forwarded to the specified IP address.
5.3.6.2 DMZ
DMZ: The DMZ Host is a local computer exposed to the Internet. When setting a particular
internal IP address as the DMZ Host, all incoming packets are checked by the Firewall and
NAT algorithms, it is then passed to the DMZ host when a packet received does not use a
port number in use by any other Virtual Server entries.
Page 98
98
Using port mapping does have security implications, since outside users
attempts to your public IP address accessing the specified PC.
Attention
are able to connect to PCs on your network. For this reason you are
advised to use specific Virtual Server entries just for the ports your
application requires instead of simply using DMZ or creating a Virtual
Server entry for “All” protocols, as doing so results in all connection
1. If you disable the NAT option in the WAN-ISP section, the Virtual
Server function becomes invalid.
2. 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 easiest way of configuring Virtual Servers is to manually
assign a static IP address to each virtual server PC, with an address
that does not fall into the range of IP addresses that are issued by the
DHCP server. You can configure the virtual server IP address
manually, but it must still be in the same subnet as the router.
5.3.7 Time Schedule
The Time Schedule supports up to 16 time slots which helps you to manage your Internet
connection. In each time profile, you may schedule specific day(s) i.e. Monday through
Sunday to restrict or allowing the usage of the Internet by users or applications.
This Time Schedule correlates closely with router’s time, since router does not have a real
