Introduction

1.1 I nt roducing the BEC 7300N

Thank you for purchasing the BEC 7300N Router. Your new router is an all-in-one unit that combines an ADSL modem, ADSL2/2+ router and Ethernet network switch to provide everything you ne ed to get the mach ines on your netw or k connected to the I nter net over an ADSL broadband connection.

The BEC 7300N router complies with ADSL2+ standards for deployment worldwide and supports downstr eam rates o f up to 24 M bps and upst rea m rates of up t o 1 Mbps. Desig ned for small office, home office and residential users, the router enables even faster Internet connections. You can enjoy AD SL services and broadband multimedia appl icati ons suc h as interactive gaming, video streaming and real-time audio much easier and faster than ever before.

The BEC 7300N 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) t o est abl ish a co nnec tio n w ith your ISP. Your new router also su ppor t s VC-based and LLC-ba sed mul ti plexing.

The perfect solution for connecting a small group of PCs to a high-speed br oadband Intern et connection, the BEC 7300N allows multiple users to have high-speed Internet access simultaneously.

Your new router also serves as an Internet firewall, protecting your network from access by outside users. Not only does it provide a natural firewall function with Network Address Translati on (NAT), it also provides r ich firew all featur es to sec ure y our networ k. All i ncoming data packets are monitored and filtered. You can also configure your new router to block internal users from accessi ng the Int er net.

Page 5

The BEC 7300N provides two levels of security support. First, it masks LAN IP addresses making them invisible to outside users on the Internet, so it is much more difficult for a hacker to target a machine on your network. Second, it can block and redirect certain ports to limit the services that ou t si de users can access. To ensure that games and other I nt er net applications run properly, you can open specific ports for outside users to access internal services on your network.

The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow multiple users to get IP addresses automatically when the router boots up. Simply set local machines as a DHCP client to accept a dynamically assigned IP address from the DHCP server and reboot. Each time a local machine is powered up; the router recognizes it and assigns an IP address to instantly connect it to the LAN.

For advanced users, Virtual Service (port mapping) functions allow the product to provide limited visibility to local machines with specific se rvices for outside users. For instance, a dedicated web server can be connected to the Internet via the router and then incoming requests for web pages that are received by the router can be rerouted to your dedicated local web server, even though the server now has a different IP address.

Virtual Serv er can also be used to r e-task se rvices t o multiple se rvers. F or insta nce, you ca n set the router to allow separated F TP, Web, an d Multiplayer game servers t o share the same Internet-visible IP address while still protecting the servers and LAN users from hackers.

1.2 Features

Express Internet A ccess – ADSL2/2+ capable

The BEC 730 0N compl ies w ith ADSL worldwide standards. S upport ing dow nstream rates of 8Mbps with ADSL, the r outer is ca pable of up to 12/24 Mbps with ADSL2/2+, and upstream rates of up to 1 Mbps. Users enjoy not only high-speed ADSL services but also broadband multimedia applications such as interactive gaming, video streaming and real-time audio which are easier and faster than ever. The router is compliant with Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (ITU G.992.1); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3); and G.dmt.bisplus (ITU G.992.5)

802.11n Wireless AP with WPA Support

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 Wirele ss Prot ected Acce ss (WPA) and Wireless En cry ption Protoc ol ( 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.

Page 7

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 Addr ess T ranslatio n Network Address Tra nsl ation ( NA T) allow s mul tiple use rs t o access outsi d e resour ces s uc h 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 su pports si mple firew alls and pr ovides opti ons for blocki ng acce ss fro m 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 addre ss is the WAN IP addre ss. To use t he serv ice, you must fir st 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 pay ing for one access account. No PP PoE client so ftware is req uired for the local co mputer. Automa tic R eco nnect and Disco nnect Timeo ut (Idle Timer ) function s are also provided.

Quality of Service (QoS)

Page 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 Internal IP address, External IP address, protocol, and port. You can thr ottl e the speed at whi ch different types o f outgoing data pass through the router, to e nsure P 2P users d on’t satur ate u ploa d bandw i dth, or office brow si ng doesn’t bring cli ent web serv ing to a halt. In additi on, or alt ernativel y, you can sim ply 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 ar e visible to outside user s. The router detect s an incoming service request and forw ards i t to the speci fic l ocal co mputer for hand ling. F or example, you can assign a PC i n a LAN to act as a Web serv er inside and ex pose it to the o utside netw ork. Outside users can br owse inside the web se rver directly whi le it is prot ected 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 GU I.

Product Overview

Standards-Based Technology

The BEC 7300N Wireless Rout er utiliz es the 802.11n st andard. The IEEE 802.11n standard is an extension of t he 802.11g standard. It incr eases t he dat a rate up to 300 Mb ps w ithin th e

2.4GHz band, utiliz ing OFDM technology . This means that in most env ironments, w ithin the specified range of t hi s device, you will be abl e to t ransfer large files quickly or even w atch 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-si gnals that are then t ransmitted si multaneously at different fr equencies to the receiver. OFDM reduces the amount of crosstalk (interference) in signal transmissions.

Installation Considerations

The BEC 7 300N Wirel ess Router le ts you acc ess your ne twork, usin g a wirel ess connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and l ocation o f walls, cei lings, or other objects that th e wirel ess signals must p ass.

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 impe de the w ireless si gnal - a solid metal door or alu minium st uds may hav e a negative effect on range.

Try to position wireless devices and computers with wireless adapters so that the signal passes throug h dr y wall or open doorw ay s and not other materials. Keep your product away (at least 3-6 feet or 1-2 meter s) from electrical devices or appliances that generate extreme RF (radio frequency) noise.

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, sim ply enter i t s IP address as shown above. Your ISP may prov i de an SN TP server for you to use.

Resync Period (in minutes) is th e per iodic i nter v al the rout er w ai ts be fore it resy nch ro niz es 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.

DO NOT power down the router or int err upt t h e firmware upgrade w hil e i t is still in process. Improper oper atio n may damage th e rout er. Please see section 2.4 for emergency recovery procedures.

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 dedica ted compu ter , and the fir mware as the so ftware 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 Firmwar e 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 thre e

minutes.

5.3.3.3 Backup / Restore

These functions al low y ou to sav e and back u p your ro uter’s cur rent setting s to a file on you r 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. Setting s f il e s s ave d t o yo ur 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.

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 w ith a password. Y ou can s et up multiple user accounts, each w ith their own password.

You are able to Edit existing users and Add new users who are able to acce ss the device’s configuration interface. Once you have clicked Edit on the account you want to edit, the information of t he account w ill be display ed above. Just go ahea d and change t he passw ord. 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 a ny oth er creat ed acc ount s by clicki ng ticki ng th e box un der Delete and then press the Edit/Delete button.

You are strongly advised to ch a ng e the password on the defaul t “ 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 helpi ng to prevent att acks from hac kers. In additi on to this, when using NA T (Network Address Transl ation) the router act s as a “natural” Internet firew all, 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

When using Virtual Servers (port mapping) your PCs are exposed to the

ports specified opened in your firewall packet filter settings.

Firewall: Prevents access from outside your network. NAT na tural firewall: This masks LAN users’ IP addresses, which are invisible to outside

users on the Int er ne t, making it much m or e difficult for a hacke r to targ et a mac hi ne on your network. This natur al fi r ewall is on when the NAT function is en abl e d.

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 computers accessing the Internet. URL Filter: Blocks PCs on your local network from unwanted websites.

Page 80

A detailed explanation of each of the following five items appears in the Firewall section below: Packet Filter, M AC 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 acc ess, or yo u can di sable specific service requests (Port number) to /from Internet. This configurat ion progr am allows you to set up to 6 differen t 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

Rule Name: Users-define description to ident ify this entr y . The maximum name leng th 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 wi sh to s earch for the conne ction-bas ed appl ication serv ice on th e 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 T ime Schedule section.

Log: Choose “log” if you wish to generate logs when the filer rule is applied to a packet.

Add: Click this butt on to add a new packe t filt er rule and th e added r ule wi ll 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”.

Page 82

5.3.4.2 MAC Filte r

A MAC (Media Access Control) address is the unique network hardware identifier for each PC on your netw ork’s interface (i.e. its Netw ork Int er face C ard or Ether net ca rd). U sing y our 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.

If the DHCP serv er option i s enabled, y ou mus t be very careful i n assigni ng IP addresses o f a filtered privat e IP rang e to av oid conflict s because y ou do 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 same subnet with the router.

Attention

Page 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 speci fic eq uipment or the entire n etwork. If this happe ns, users w ill 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 t hreshold v alue to decid e whether an ICMP Ech o Storm is occurring or not. Default value is 15 ICMP Echo Requests (PING) per second.

Maximum ICMP Count: This is a thr eshold t o decide whet her an ICM P flood is occu rring or not. Default v alue is 100 ICM P packets per seconds exce pt ICMP Echo Req uests (PING) .

Log: Check Log if y ou wish to generate logs w hen th e fil er rule is ap pli ed t o th e Intrusion Detection.

Page 84

For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event Log but it will not be able to protect against such attacks.

Dst Port: Destination Port Dst IP: Destination IP

Check Enable if you wish to exclude outside PING requests from reaching this router.

URL (Uniform Resour ce 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.

filter blocks web browser (HTTP) connection attempts using port 80 only. For example, the UR L http://www.abc.com/abcde.html woul d be dro pped si nce the ke yw ord

“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 th e UR L to determine if it is in the trusted list . If y es, the co nnecti on

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 (Q u ality of Service)

Quality of Service Introduc t ion

If you’ve ever foun d your ‘net’ speed has slowed to a crawl beca use anot her famil y mem ber is using a P2P file sharing program, you’l l understand why the Qualit y of S er vice 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) gi ves you full control over w hich types of o utgoing da ta tr affic s hould be g iven priority by the router, ensuring bandwidth-consumption data like gaming packets, latency-sensitiv e application like voice, or even mi ssion 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

Direction: The traffic flow direction to be controlled by the QoS policy.

There are two settings to be provided in the Router:  L AN 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 L AN : 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: Differenti ated Ser vices Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP Mar king allow s user s to cl assify traf fic based on D SCP v alue an d sen d p acke t s 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 av ailable bandw idth that is not used , it will be given to this p olicy by following priority assignment.

Ratio: Assign th e data rat io for this poli cy to be cont rolled. For ex amples, we w ant 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, t he est imated data r ate, in kbps, for t hi s r ul e i s 20%*256*0.9 = 4 6kbps. (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

Priority: Specify the priority for the bandwidth that is not used. For examples, you may

specify two dif ferent QoS policies for different applications. Bo th 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 A ddress: The IP address values for Local L AN machine s you w ant to control . (For IP p acket s from LAN to W AN, i t is t he so urce IP ad dress. F or IP p ackag es from W AN t o LAN, it is the destination IP address.)

Internal Port: The Application port values for local LAN machines you want to control. (For TCP/UDP p acke t s from LAN to WAN, it is the source port val ue. F or TCP/U DP pack et s 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 uni que p aramet er val ues for I nternet protoc ols. P ort number s 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.

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 Add ress: Enter the IP address of a specific internal ser ver 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 “natur al” Internet firewall, your router protect s your network fro m 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 outsi de users to access inter nal ser ver s, e.g. a web se rver, FTP server, Email server or game ser ver, the router can act as a “v irtual serv er”. You can set up a local server w ith a speci fic port n umber for the serv ice 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 intern al ser ver.

For example, if you set the port number 80 (Web/HTTP) to be mapped to the IP Address

192.168.1.2, then all in coming H TTP req ues ts fro m out sid e users are forwar ded to t he loc al 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

In addition to specifying the port number used, you also need to specify the protocol used. The protocol is determined by the particu lar appl ication . Most applic ations use TCP or UDP, however you can specify other protocols using the drop-down Protocol m enu. Se tting 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

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 time clock on board; it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP serv er fro m the Int ernet. R efer t o T ime Zon e for details. You router time should correspond with your local time. If the time is not set correctly, your Time Schedule will not function properl y.

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 w ay of con figuring V irtua l Servers is to manual ly assign a static IP address to each virtual server PC, with an address that does not fall i nto th e rang e o f IP ad dresse s tha t ar e issu ed 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.

Attention

Using port mapping does have security implications, since outside users 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

Serv

er entry for “All” protocols, as doing so results in all connection

attempts to your public IP address accessing the specified PC.

5.3.8 Advanced

Configuration options within the Advanced section are for users who wish to take advantage of the more advanced features of the router. Users who do not understand the features should not attempt to reconfigure their router, unless advised to do so by support staff.

There are seven items within the Advanced section: Static Route, Dynamic DNS, VLAN, Device Management, IGMP, SNMP Access Control and Remote Access.
