Chapter 1: Introduction

Introduction to your Router

Welcome to the BiPAC 7402NX(L) 802.11n 3G/ ADSL2+ (VPN) Firewall Router. The router is an

“all-in-one” ADSL router, combining an ADSL modem, ADSL router and Ethernet network switch functionalities, providing everything you need to get the machines on your network connected to the

Internet over your ADSL broadband connection. With features such as an ADSL Quick-Start wizard and

DHCP Server, you can be online in no time at all and with a minimum of fuss and configuration, catering for first-time users to the guru requiring advanced features and control over their Internet connection and network.

Features

This router complies with worldwide ADSL standards. It supports downstream rates of up to 12/24

Mbps with ADSL2/2+, 8 Mbps with ADSL, and upstream rates of up to 1 Mbps. With this technology, users enjoy not only high-speed ADSL service but also broadband multimedia applications such as interactive gaming, video streaming and real-time audio much more quickly and easily than ever. In particular, by doubling the upstream data rate, the Annex M standard included in the BiPAC 7402NX model supports the latest ADSL2/2+ for higher upload speeds.

Virtual Private Network (VPN) (VPN model only)

It allows user to make a tunnel with a remote site directly to secure the data transmission among the connection. User can use embedded PPTP and L2TP client/server, IKE and IPSec which are supported by this router to make a VPN connection or users can run the PPTP client in PC and the router already provides IPSec and PPTP pass through function to establish a VPN connection if the user likes to run the PPTP client in his local computer.

3G

With 3G-based Internet connection (requires an additional 3G USB modem), user can access internet through 3G - whether you're seated at your desk or taking a cross-country train trip.

EWAN

Besides using 3G/ADSL to get connected to the Internet, the router offers its Ethernet port 1 as a

WAN port to be used to connect to Cable Modems and fiber optic lines. This alternative, yet faster method to connect to the internet will provide users more flexibility to get online.

Dual WAN

Dual WAN is a new way of getting connected to the internet which is to use each two of the

3G/ADSL/EWAN to deal with the unexpected case and balance traffic load. That is a way of improving greatly the robustness.

802.11n Wireless AP with WPA Support

With an integrated 802.11n Wireless Access Point in the router, the device delivers up to 6 times faster speeds and 3 times farther range than an 802.11b/g wireless network. It offers a quick yet easily accessible and mobile to the users among wired network, wireless network, broadband connection (ADSL). In addition to having a 300Mbps. data rate, it is also backward compatible with existing 802.11b/11g equipments. The supported features of Wi-Fi Protected Access (WPA-PSK/

WPA2-PSK) and Wired Equivalent Privacy (WEP) enhance the security level of data protection and access control via Wireless LAN.

Fast Ethernet Switch

A 4-port 10/100/1000Mbps fast Ethernet switch is built in with automatic switching between MDI and MDI-X for 10Base-T, 100Base-TX and 1000Base-TX ports. An Ethernet straight or crossover cable can be used directly for auto detection.

Multi-Protocol to Establish a Connection

It supports PPPoA (RFC 2364 - PPP 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 the ISP. The product also supports VC-based and LLC-based multiplexing.

Quick Installation Wizard

It supports a WEB GUI page to install this device quickly. With this wizard, end users can enter the information easily which they get from their ISP, then surf the Internet immediately.

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. It makes network simple and affordable for users. UPnP architecture leverages TCP/IP and the Web to enable seamless proximity networking in addition to control and data transfer among networked devices. With this feature enabled, users can now connect to Net meeting or MSN Messenger seamlessly.

Network Address Translation (NAT)

Allows multi-users to access outside resources such as the Internet simultaneously with one IP address/one Internet access account. Many application layer gateway (ALG) are supported such as web browser, ICQ, FTP, Telnet, E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.

SOHO Firewall Security with DoS and SPI

Along with the built-in NAT natural firewall feature, the router also provides advanced hacker pattern-filtering protection. It can automatically detect and block Denial of Service (DoS) attacks.

The router is built with Stateful Packet Inspection (SPI) to determine if a data packet is allowed through the firewall to the private LAN.

Domain Name System (DNS) Relay

It provides an easy way to map the domain name (a friendly name for users such as www.yahoo.com) and IP address. When a local machine sets its DNS server with this router’s IP address, every DNS conversion request packet from the PC to this router will be forwarded to the real DNS in 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. For example, to use the service, you must first apply for an account from a DDNS service like http://www.dyndns.org/. More than 5 DDNS servers are supported.

Quality of Service (QoS)

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 source IP address, destination IP 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.

IPv6 supported

Internet Protocol version 6 (IPv6) is a version of the Internet Protocol that is designed to succeed

IPv4.

IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about 3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic and eliminates the primary need for network address translation (NAT), which gained widespread deployment as an effort to alleviate IPv4 address exhaustion.

IPv6 also implements new features that simplify aspects of address assignment (stateless address autoconfiguration) and network renumbering (prefix and router announcements) when changing

Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the host identifier from Link Layer media addressing information (MAC address).

Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security

(IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4

(into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a fundamental interoperability requirement.

Virtual Server (“port forwarding”)

Users can specify some services to be visible from outside users. The router can detect incoming service requests and forward either a single port or a range of ports to the specific local computer to handle it. For example, a user can assign a PC in the LAN acting as a WEB server inside and expose it to the outside network. Outside users can browse inside web servers directly while it is protected by NAT. A DMZ host setting is also provided to a local computer exposed to the outside network, Internet.

Rich Packet Filtering

Not only filters the packet based on IP address, but also based on Port numbers. It will filter packets from and to the Internet, and also provides a higher level of security control.

Dynamic Host Configuration Protocol (DHCP) Client and Server

In the WAN site, the DHCP client can get an IP address from the Internet Service Provider (ISP) automatically. In the LAN site, the DHCP server can allocate a range of client IP addresses and distribute them including IP address, subnet mask as well as DNS IP address to local computers. It provides an easy way to manage the local IP network.

Static and RIP1/2 Routing

It has routing capability and supports easy static routing table or RIP1/2 routing protocol.

Simple Network Management Protocol (SNMP)

It is an easy way to remotely manage the router via SNMP.

Web based GUI

It supports web based GUI for configuration and management. It is user-friendly and comes with on-line help. It also supports remote management capability for remote users to configure and manage this product.

Firmware Upgradeable

Device can be upgraded to the latest firmware through the WEB based GUI.

Rich Management Interfaces

It supports flexible management interfaces with local console port, LAN port, and WAN port. Users can use terminal applications through the console port to configure and manage the device, or

Telnet, WEB GUI, and SNMP through LAN or WAN ports to configure and manage the device.

Cabling

One of the most common causes of problems is the bad cabling or ADSL line(s). Make sure that all connected devices are turned on. On the front of the product is a bank of LEDs. Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify that you are using the proper cables.

Ensure that all other devices connected to the same telephone line as your router (e.g. telephones, fax machines, analogue modems) have a line filter connected between them and the wall socket (unless you are using a Central Splitter or Central Filter installed by a qualified and licensed electrician), and ensure that all line filters are correctly installed and the right way around. Missing line filters or line filters installed the wrong way around can cause problems with your ADSL connection, including causing frequent disconnections.

Chapter 3: Basic Installation

The router can be configured with your web browser. A web browser is included as a standard application in the following operating systems: Linux, Mac OS, Windows 7/98/NT/2000/XP/Me, etc. The product provides an easy and user-friendly interface for configuration.

Please 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.

There are ways to connect with the router, either through an external repeater hub to the router or directly connecting with PCs. However, to be sure PCs have an Ethernet interface installed properly prior to connecting to the router device. You ought to configure your PCs 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 of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the PC to get an IP address automatically from the router using DHCP. If you encounter any problem accessing the router’s web interface it may also be advisable to uninstall any kind of software firewall on your PCs, as they can cause problems accessing the 192.168.1.254 IP address of the router. Users should make their own decisions on how to best protect their network.

Please follow the steps below for your PC’s network environment installation.

Any TCP/IP capable workstation can be used to communicate with or through the router. To configure other types of workstations, please consult the manufacturer’s documentation.

39


IPv6 Autoconfig

The IPv6 address composes of two parts, thus, the prefix and the interface ID.

BiPAC 7402NX(L) dynamically configure IPv6 address on host with Stateless auto-configuration mode.

Stateless auto-configuration requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information (MAC address) and information(prefix) advertised by routers. Routers advertise prefixes that identify the subnet(s) associated with a link, while hosts generate an "interface identifier" that uniquely identifies an interface on a subnet. An address is formed by combining the two. When using stateless configuration, you needn’t configure anything on the client.

Link Local Address: the Link local address for this device.

Dynamic IPv6 Address: this field displays the dynamic obtained IPv6 address if you haven’t set static

IPv6 address.

58


Port Setting

This section allows you to configure the settings for the router’s Ethernet ports to solve some of the compatibility problems that may be encountered while connecting to the Internet, as well allowing users to tweak the performance of their network.

Port # Connection Type: There are Six options to choose from: Auto, 10M half-duplex, 10M full-duplex,

100M half-duplex, 100M full-duplex, 1000M full-duplex and Disable. Sometimes, there are Ethernet compatibility problems with legacy Ethernet devices, and you can configure different types to solve compatibility issues. The default is Auto, which users should keep unless there are specific problems with PCs not being able to access your LAN.

IPv4 TOS priority Control (Advanced users): TOS, Type of Services, is the 2 nd octet of an IP packet.

Bits 6-7 of this octet are reserved and bit 0-5 are used to specify the priority of the packet.

This feature uses bits 0-5 to classify the packet’s priority. If the packet is high priority, it will flow first and will not be constrained by the Rate Limit. Therefore, when this feature is enabled, the router’s Ethernet switch will check the 2 nd octet of each IP packet. If the value in the TOS field matches the checked values in the table (0 to 63), this packet will be treated as high priority.


59


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.

To disable the router’s DHCP Server, check Disabled and click Next, then click Apply. When the DHCP

Server is disabled you will need to manually assign a fixed IP address to each PCs on your network, and set the default gateway for each PCs to the IP address of the router (by default this is 192.168.1.254).

To configure the router’s DHCP Server, check DHCP Server and click Next. 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 will perform the domain name lookup, find the IP address from the outside network automatically and forward it back to the requesting PC in the LAN (your Local Area Network).

If you check DHCP Relay Agent and click Next, then you will have to enter the IP address of the DHCP server which will assign 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.

60



WAN - Wide Area Network

WAN refers to your Wide Area Network connection, i.e. your router’s connection to your ISP and the

Internet. Here are the items within the WAN section: WAN Interface, WAN Profile and ADSL Mode.

System

Here are the items within the System section: Time Zone, Remote Access, Firmware Upgrade,

Backup/Restore, Restart and User Management.

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 will retrieve the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP server other than those in the list, simply enter its IP address as shown above. Your ISP may provide an

SNTP server for you to use.

Daylight Saving is also known as Summer Time Period. Many places in the world adapt it during summer time to move one hour of daylight from morning to the evening in local standard time. Check

Automatic box to auto set your local time.

Resync Period (in minutes) is the periodic interval the router will wait before it re-synchronizes the router’s time with that of the specified SNTP server. In order 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.

81


Remote Access


To temporarily permit remote administration of the router (i.e. from outside your LAN), select a time period the router will permit remote access for and click Enable. You may change other configuration options for the web administration interface using Device Management options in the Advanced section of the GUI.

If you wish to permanently enable remote access, choose a time period of 0 minute.

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 revised, and your router allows you to upgrade the software it runs to take advantage of these changes.

Clicking on Browse will allow 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.


82

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.

After selecting the settings file you wish to use, pressing Restore will load those settings into the router.


83


Restart Router

Click Restart with option Current Settings to reboot your router (and restore your last saved configuration).

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.

You may also reset your router to factory settings by holding the small Reset pinhole button more than 6 seconds on the back of your router.

Caution: After pressing the RESET button for more than 6 seconds, to be sure you power cycle the device again.

84


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 on Edit, you are shown the following options:

You can change the user’s password, whether their account is active and valid, as well as add a comment to each user account. Click Edit/Delete button to save your revise. You cannot delete the default admin account, if you do you will be log out. However, you can delete any other created accounts by clicking Delete when editing the user. 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.

85



When you create a user account, you check Valid to fill in the blank with User, Comment, Password and

Confirm Password. Later, click Add button to add your new user account.

For deleting the user account, you choose Delete option. In the end, you click Edit/Delete button to delete the chosen user account.

86



Mail Alert

Recipient’s Email (WAN IP Change Alert): Enter the email address that will receive the alert message once an WAN IP change has been detected.

87


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. Besides, when using NAT, the router acts as a “natural” Internet firewall, as all PCs on your LAN will use private IP addresses that cannot be directly accessed from the Internet.

Firewall: Prevents access from outside your network. The router provides three levels of security support:

NAT natural firewall: This masks LAN users’ IP addresses which is 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 NAT function is enabled.

When using Virtual Servers your PCs will be exposed to the degree specified in your Virtual Server settings provided the ports specified are opened in your firewall packet filter settings.

Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to prevent unauthorized computers or applications accessing your local network from the Internet.

Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks.

Access Control: Prevents access from PCs on your local network:

Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to prevent unauthorized computers or applications accessing the Internet.

URL Filter: To block PCs on your local network from unwanted websites.

Here are the items within the Firewall section: General Settings, Packet Filter, Intrusion Detection,

URL Filter, IM/P2P Blocking and Firewall Log.

88



General Settings

You can choose not to enable Firewall and still able to access to URL Filter, Intrusion Detection and

IM/P2P Blocking or enable the Firewall using preset filter rules and modify the port filter rules as required.

The Packet Filter is used to filter packets based-on Applications (Port) or IP addresses.

There are four options when you enable the Firewall, they are:

 All blocked/User-defined: no pre-defined port or address filter rules by default, meaning that all inbound (Internet to LAN) and outbound (LAN to Internet) packets will be blocked. Users have to add their own filter rules for further access to the Internet.

 High/Medium/Low security level: the predefined port filter rules for High, Medium and Low security are displayed in Port Filters of Packet Filter.

Select either High, Medium or Low security level to enable the Firewall. The only difference between these three security levels is the preset port filter rules in the Packet Filter. Firewall functionality is the same for all levels; it is only the list of preset port filters that changes between each setting. For more detailed on level of preset port filter information, refer to Table 1: Predefined Port Filter.

If you choose of the preset security levels and add custom filters, this level of filter rules will be saved even and do not need to re-configure the rules again if you disable or switch to other firewall level.

The “Block WAN Request” is a stand-alone function and not relate to whether security enable or disable.

Mostly it is for preventing any scan tools from WAN site by hacker. blocking all the accesses to configure and manage of the device from the

Internet.

89



Packet Filter

This function is only available when the Firewall is enabled and one of these four security levels is chosen

(All blocked, High, Medium and Low). The preset port filter rules in the Packet Filter must modify accordingly to the level of Firewall, which is selected. See Table1: Predefined Port Filter for more detail information.


90


Example: Predefined Port Filters Rules

The predefined port filter rules for High, Medium and Low security levels are listed. See Table 1.

Note: Firewall – All Blocked/User-defined, you must define and create the port filter rules yourself. No predefined rule is being preconfigured.

Example: Configuring your firewall to allow a publicly accessible web server on your LAN

The predefined port filter rule for HTTP (TCP port 80) is the same no matter whether the firewall is set to a high, medium or low security level. To setup a web server located on the local network when the firewall is enabled, you have to configure the Port Filters setting for HTTP.

As you can see from the diagram below, when the firewall is enabled with one of the three presets

(Low/Medium/High), inbound HTTP access is not allowed which means remote access through HTTP to your router is not allowed.

Note: Inbound indicates accessing from Internet to LAN and Outbound is from LAN to the Internet.

94

Note: For how to configure the HTTP in Virtual Server, go to Add Virtual Server in Virtual Server section for more details.

96


Intrusion Detection


The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts from the Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and blocked depending on whether they are detected as possible hacker attacks, intrusion attempts or other connections that the router determines to be suspicious.

Blacklist: If the router detects a possible attack, the source IP or destination IP address will be added to the Blacklist. Any further attempts using this IP address will be blocked for the time period specified as the

Block Duration. The default setting for this function is false (disabled). Some attack types are denied immediately without using the Blacklist function, such as Land attack and Echo/CharGen scan.

Intrusion Detection: If enabled, IDS will block Smurf attack attempts. Default is false.

Block Duration:

 Victim Protection Block Duration: This is the duration for blocking Smurf attacks. Default value is 600 seconds.

 Scan Attack Block Duration: This is the duration for blocking hosts that attempt a possible

Scan attack. Scan attack types include X’mas scan, IMAP SYN/FIN scan and similar attempts.

Default value is 86400 seconds.

 DoS Attack Block Duration: This is the duration for blocking hosts that attempt a possible

Denial of Service (DoS) attack. Possible DoS attacks this attempts to block include Ascend Kill and

WinNuke . Default value is 1800 seconds.

Max 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.

Max 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.

Max 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).

Clear Blacklist: Clear the current blacklist.

Blacklist: Show the blacklist information.

For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event Log. It cannot protect against such attacks.

URL Filter

URL (Uniform Resource Locator – e.g. an address in the form of http://www.abcde.com

or http://www.example.com

) filter rules allow you to prevent users on your network from accessing particular websites by their URL. There are no pre-defined URL filter rules; you can add filter rules to meet your requirements.

Enable/Disable: To enable or disable URL Filter feature.

Block Mode: It can support up to 4 timeslots.

Disabled: No action will be performed by the Block Mode.

Always On: Action is enabled. URL filter rules will be monitoring and checking all hours of the day.

TimeSlot1 ~ TimeSlot16: It is self-defined time period. You may specify the time period to check the URL filter rules, i.e. during working hours. For setup and detail, refer to Time

Schedule section.

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 will be checked to see if any keywords are present in URLs accessed to determine if the connection attempt should be blocked. Please note that the URL filter blocks web browser (HTTP) connection attempts using port 80 only.

For example , if the URL is http://www.abc.com/abcde.html

, it will be dropped as the keyword “abcde” occurs in the URL.

99



Domains Filtering: This function checks the whole URL not the IP address, in URLs accessed against your list of domains to block or allow. If it is matched, the URL request will be sent (Trusted) or dropped

(Forbidden). For this function to be activated, both check-boxes must be checked. Here is the checking procedure:

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, check if it is listed in the forbidden list. If yes, then the connection attempt will be dropped.

3. If the packet does not match either of the above two items, 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

”

In the example below, the URL request for www.abc.com

will be sent to the remote web server because it is listed in the trusted list, whilst the URL request for www.google

or www.google.com

will be dropped, because www.google

is in the forbidden list.

Example: Andy wishes to disable all WEB traffic except for ones listed in the trusted domain, which would prevent Bobby from accessing other web sites. Andy selects both functions in the Domain

Filtering and thinks that it will stop Bobby. But Bobby knows this function, Domain Filtering, ONLY disables all WEB traffic except for Trusted Domain, BUT not its IP address. If this is the situation,

Block surfing by IP address function can be handy and helpful to Andy. Now, Andy can prevent Bobby from accessing other sites.

Restrict URL Features: This function enhances the restriction to your URL rules.

 Block Java Applet: This function can block Web content that includes the Java Applet. It is to prevent someone who wants to damage your system via standard HTTP protocol.

 Block surfing by IP address: Preventing someone who uses the IP address as URL for skipping Domains Filtering function. Activates only and if Domain Filtering enabled.

101



IM / P2P Blocking

IM, short for Instant Message, is required to use client program software that allows users to communicate, in exchanging text message, with other IM users in real time over the Internet. A P2P application, known as Peer-to-peer, is group of computer users who share file to specific groups of people across the Internet. Both Instant Message and Peer-to-peer applications make communication faster and easier but your network can become increasingly insecure at the same time. Billion’s IM and P2P blocking helps users to restrict LAN PCs to access to the commonly used IM, Yahoo and MSN, and P2P,

BitTorrent and eDonkey, applications over the Internet.

Instant Message Blocking: The default is set to Disabled.

 Disabled: Instant Message blocking is not triggered. No action will be performed.

 Always On: Action is enabled.

 TimeSlot1 ~ TimeSlot16: This is the self-defined time period. You may specify the time period to trigger the blocking, i.e. during working hours. For setup and detail, refer to Time Schedule section.

Yahoo/MSN Messenger: Check the box to block either or both Yahoo or/and MSN Messenger. To be sure you enabled the Instant Message Blocking first.

Peer to Peer Blocking: The default is set to Disabled.

 Disabled: Instant Message blocking is not triggered. No action will be performed.

 Always On: Action is enabled.

 TimeSlot1 ~ TimeSlot16: This is the self-defined time period. You may specify the time period to trigger the blocking, i.e. during working hours. For setup and detail, refer to Time Schedule section.

BitTorrent / eDonkey: Check the box to block either or both Bit Torrent or/and eDonkey. To be sure you enabled the Peer to Peer Blocking first.

VPN - Virtual Private Networks

(BiPAC 7402NX only)

Virtual Private Networks is ways to establish secured communication tunnels to an organization’s network via the Internet. Your router supports three main types of VPN (Virtual Private Network), PPTP, IPSec and L2TP.

PPTP (Point-to-Point Tunneling Protocol)

There are two types of PPTP VPN supported; Remote Access and LAN-to-LAN (please refer below for more information.). Click Configuration/VPN/PPTP.

Name: A given name for the connection.

Active: This function activates or deactivates the PPTP connection. Check Active checkbox if you want the protocol of tunnel to be activated and vice versa.

Note: When the Active checkbox is checked, the function of Edit and Delete will not be available.

Connection Type: It informs your PPTP tunnel connection condition.

Type: This refers to your router operates as a client or a server, Dialout or Dialin respectively.

PPTP Connection - Remote Access

Name: A given name for the connection (e.g. “connection to office”).

Connection Type: Remote Access or LAN to LAN

Type: Check Dial Out if you want your router to operate as a client (connecting to a remote VPN server, e.g. your office server), check Dial In operates as a VPN server.

 When configuring your router as a Client, enter the remote Server IP Address (or Domain

Name) you wish to connect to. a) When configuring your router as a server, enter the Private IP Address Assigned to Dial in

User address.

Username: If you are a Dial-Out user (client), enter the username provided by your Host. If you are a

Dial-In user (server), enter your own username.

104



Password: If you are a Dial-Out user (client), enter the password provided by your Host. If you are a

Dial-In user (server), enter your own password.

Authentication Type: Default is Auto if you want the router to determine the authentication type to use, or else manually specify CHAP (Challenge Handshake Authentication Protocol) or PAP (Password

Authentication Protocol) if you know which type the server is using (when acting as a client), or else the authentication type you want clients connecting to you to use (when acting as a server). When using PAP, the password is sent unencrypted, whilst CHAP encrypts the password before sending, and also allows for challenges at different periods to ensure that an intruder has not replaced the client.

Data Encryption: Data sent over the VPN connection can be encrypted by an MPPE algorithm. Default is Auto, so that this setting is negotiated when establishing a connection, or else you can manually

Enable or Disable encryption.

Key Length: The data can be encrypted by MPPE algorithm with 40 bits or 128 bits. Default is Auto, it is negotiated when establishing a connection. 128 bit keys provide stronger encryption than 40 bit keys.

Mode: You may select Stateful or Stateless mode. The key will be changed every 256 packets when you select Stateful mode. If you select Stateless mode, the key will be changed in each packet.

Active as default route: Commonly used by the Dial-out connection which all packets will route through the VPN tunnel to the Internet; therefore, active the function may degrade the Internet performance.

.

Hash Function: It is a Message Digest algorithm which coverts any length of a message into a unique set of bits. It is widely used MD5 (Message Digest) and SHA-1 (Secure Hash Algorithm) algorithms.

SHA1 is more resistant to brute-force attacks than MD5, however it is slower.

 MD5: A one-way hashing algorithm that produces a 128−bit hash.

 SHA1: A one-way hashing algorithm that produces a 160−bit hash

Encryption: Select the encryption method from the pull-down menu. There are several options, DES,

3DES and AES (128, 192 and 256). 3DES and AES are more powerful but increase latency.

c) DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method. d) 3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method.

 AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as encryption method.

DH (Diffie-Hellman) Group: It is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes,

MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for Modular Exponentiation Groups.

IPSec Proposal: Select the IPSec security method. There are two methods of checking the authentication information, AH (authentication header) and ESP (Encapsulating Security Payload). Use

ESP for greater security so that data will be encrypted and authenticated. Using AH data will be authenticated but not encrypted.

Authentication: Authentication establishes the integrity of the datagram and ensures it is not tampered with in transmit. There are three options, Message Digest 5 (MD5), Secure Hash Algorithm (SHA1) or

NONE. SHA1 is more resistant to brute-force attacks than MD5, however it is slower. e) MD5: A one-way hashing algorithm that produces a 128−bit hash. f) SHA1: A one-way hashing algorithm that produces a 160−bit hash.

Encryption: Select the encryption method from the pull-down menu. There are several options, DES,

3DES, AES (128, 192 and 256) and NULL. NULL means it is a tunnel only with no encryption. 3DES and

AES are more powerful but increase latency. g) DES: Stands for Data Encryption Standard, it uses 56 bits as an encryption method. h) 3DES: Stands for Triple Data Encryption Standard, it uses 168 (56*3) bits as an encryption method. i) AES: Stands for Advanced Encryption Standards, you can use 128, 192 or 256 bits as encryption method.

Perfect Forward Secrecy: Choose whether to enable PFS using Diffie-Hellman public-key cryptography to change encryption keys during the second phase of VPN negotiation. This function will provide better security, but extends the VPN negotiation time. Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the

Internet). There are three modes, MODP 768-bit, MODP 1024-bit and MODP 1536-bit. MODP stands for

Modular Exponentiation Groups.

Pre-shared Key: This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters.

Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).

SA Lifetime: Specify the number of minutes that a Security Association (SA) will stay active before new encryption and authentication key will be exchanged. There are two kinds of SAs, IKE and IPSec. IKE negotiates and establishes SA on behalf of IPSec, an IKE SA is used by IKE.

 Phase 1 (IKE): To issue an initial connection request for a new VPN tunnel. The range can be

114


Billion BiPAC 7402NX(L) 802.11n 3G/ADSL2+ (VPN) Firewall Router from 5 to 15,000 minutes, and the default is 480 minutes.

 Phase 2 (IPSec): To negotiate and establish secure authentication. The range can be from 5 to

15,000 minutes, and the default is 60 minutes.

A short SA time increases security by forcing the two parties to update the keys. However, every time the VPN tunnel re-negotiates, access through the tunnel will be temporarily disconnected.

PING for Keep Alive:

None: The default setting is None. To this mode, it will not detect the remote IPSec peer has been lost or not. It only follows the policy of Disconnection time after no traffic, which the remote IPSec will be disconnected after the time you set in this function.

PING: This mode will detect the remote IPSec peer has lost or not by pinging specify IP address.

DPD: Dead peer detection (DPD) is a keeping alive mechanism that enables the router to be detected lively when the connection between the router and a remote IPSec peer has lost. Please be noted, it must be enabled on the both sites.

PING to the IP: It is able to IP Ping the remote PC with the specified IP address and alert when the connection fails. Once alter message is received, Router will drop this tunnel connection. Re-establish of this connection is required. Default setting is 0.0.0.0 which disables the function.

Interval: This sets the time interval between Pings to the IP function to monitor the connection status.

Default interval setting is 10 seconds. Time interval can be set from 0 to 3600 second, 0 second disables the function.

Disconnection Time after no traffic: It is the NO Response time clock. When no traffic stage time is beyond the Disconnection time set, Router will automatically halt the tunnel connection and re-establish it base on the Reconnection Time set. 180 seconds is minimum time interval for this function.

Reconnection Time: It is the reconnecting time interval after NO TRAFFIC is initiated. 3 minutes is minimum time interval for this function.

QoS - Quality of Service

QoS function helps you to control your network traffic for each application from LAN (Ethernet and/or

Wireless) to WAN (Internet). It facilitates you to control the different quality and speed of through put for each application when the system is running with full loading of upstream.

Here are the items within the QoS section: Prioritization and Outbound / Inbound IP Throttling

(bandwidth management).

Prioritization

There are three priority settings to be provided in the Router:

 High

 Normal (The default is normal priority for all of traffic without setting)

 Low

And the balances of utilization for each priority are High (60%), Normal (30%) and Low (10%).

To delete the application, you can choose Delete option and then click Edit/Delete.

Name: User-define description to identify this new policy/application.

Time Schedule: Scheduling your prioritization policy.

Priority: The priority given to each policy/application. Its default setting is set to High; you may adjust this setting to fit your policy/application.

Protocol: The name of supported protocol.

Source IP Address Range: The source IP address or range of packets to be monitored.

Source Port: The source port of packets to be monitored.

Destination IP address Range: The destination IP address or range of packets to be monitored.

Destination Port: The destination port of packets to be monitored.

DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP

Marking allows users to assign specific application traffic to be executed in priority by the next Router based on the DSCP value. See Table 4. The DSCP Mapping Table:

Mission-critical application

Mostly the VPN connection is mission-critical application for doing data exchange between head and branch office.

The mission-critical application must be sent out smoothly without any dropping. Set priority as high level for preventing any other applications to saturate the bandwidth.

Voice application

Voice is latency-sensitive application. Most VoIP devices are use SIP protocol and the port number will be assigned by SIP module automatically. Better to use fixed IP address for catching VoIP packets as high priority.

Above settings will help to improve quality of your VoIP service when traffic is full loading.


139


Restricted Application

Some of companies will setup FTP server for customer downloading or home user sharing their files by using FTP.

With above settings that help to limit utilization of upstream of FTP. Time schedule also help you to only limit utilization at daytime.


140


Advanced setting by using IP throttling

With IP throttling you can specify more detail for allocating bandwidth; even the applications are located in the same level.

Upstream: 928kbps (29*32kbps)

Mission-critical Application: 192kbps (6*32kbps)

Voice Application: 128kbps (4*32kbps)

Restricted Application: 160kbps (5*32kbps)

Other Applications: 448kbps (14*32kbps)

6+4+14+5=29, 29*32kbps=928kbps

Sometime your customers or friends may upload their files to your FTP server and that will saturate your downstream bandwidth. The settings below help you to limit bandwidth for the restricted application.


141


Virtual Server (known as Port Forwarding)

In TCP/IP 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 will usually need to configure your router to forward these incoming connection attempts using specific ports to the PC on your network running the application. You will also need to use port forwarding if you want to host an online game server.

The reason for this is that when using NAT, your publicly accessible IP address will be used by and point to your router, which then needs to deliver all traffic to the private IP addresses used by your PCs. Please see the WAN configuration section of this manual for more information on NAT.

The device can be configured as a virtual server so that remote users accessing services such as Web or

FTP services via the public (WAN) IP address can be automatically redirected to local servers in the LAN network. Depending on the requested service (TCP/UDP port number), the device redirects the external service request to the appropriate server within the LAN network


142


Add Virtual Server

Because NAT can act as a “natural” Internet firewall, your router protects your network from being accessed by outside users when using NAT, as all incoming connection attempts will 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 will be forwarded to the corresponding internal server.

drop-down menu to select Application: Users-define description to identify this entry or click existing predefined rules.

: 20 predefined rules are available. Application, Protocol and External/Redirect Ports will be filled after the selection.

Protocol: It is the supported protocol for the virtual server. In addition to specifying the port number to be used, you will also need to specify the protocol used. The protocol used is determined by the particular application. Most applications will use TCP or UDP.

Time Schedule: User-defined time period to enable your virtual server. You may specify a time schedule or Always on for the usage of this Virtual Server Entry. For setup and detail, refer to Time Schedule section

External Port: The Port number on the Remote/WAN side used when accessing the virtual server.

Redirect Port: The Port number used by the Local server in the LAN network.

Internal IP Address: The private IP in the LAN network, which will be providing the virtual server application. List all existing PCs connecting to the network. You may assign a PC with IP address and MAC from this list.


143


Example:

If you like to remote accessing your Router through the Web/HTTP at all time, you would need to enable port number 80 (Web/HTTP) and map to Router’s IP Address. Then all incoming HTTP requests from you

(Remote side) will be forwarded to the Router with IP address of 192.168.1.254. Since port number 80 has already been predefined, next to the Application click Helper. A list of predefined rules window will pop and select HTTP_Sever.

Application: HTTP_Sever

Time Schedule: Always On

Protocol: tcp

External Port: 80-80

Redirect Port: 80-80

IP Address: 192.168.1.254

Add: Click it to apply your settings.

Edit/Delete: Click it to edit or delete this virtual server application.

Using port forwarding does have security implications, as outside users will be 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 using DMZ. As doing so will result in all connections from the WAN attempt to access to your public IP of the DMZ PC specified.

Attention

If you have disabled the NAT option in the WAN-ISP section, the Virtual Server function will hence be invalid.

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 static IP address to each virtual server PC, with an address that does not fall into the range of IP addresses that are to be 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.

144



Edit DMZ Host

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 will be checked by the Firewall and NAT algorithms then passed to the DMZ host, when a packet received does not use a port number used by any other Virtual Server entries.

Cautious: This Local computer exposing to the Internet may face varies of security risks.

Go to ConfigurationVirtual ServerEdit DMZ Host o) Enabled: It activates your DMZ function. p) Disabled: As set in default setting, it disables the DMZ function.

Internal IP Address: Give a static IP address to the DMZ Host when Enabled radio button is checked.

Be aware that this IP will be exposed to the WAN/Internet.

List all existing PCs connecting to the network. You may assign a PC with IP address and MAC from this list.

Select the Apply button to apply your changes.


145


Edit One-to-One NAT (Network Address Translation)

One-to-One NAT maps a specific private/local IP address to a global/public IP address.

If you have multiple public/WAN IP addresses from you ISP, you are eligible for One-to-One NAT to utilize these IP addresses.

Go to ConfigurationVirtual ServerEdit One-to-one NAT

NAT Type: Select desired NAT type. As set in default setting, it disables the One-to-One NAT function.

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 server from the Internet. Refer to Time Zone for details. You router time should correspond with your local time.

If the time is not set correctly, your Time Schedule will not function properly.

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.

Here are the items within the Advanced section: Static Route, Static ARP, Dynamic DNS, Device

Management, IGMP and VLAN Bridge.

Static Route

Go to Configuration/Advanced/Static Route.

Destination: This is the destination subnet IP address.

Netmask: Subnet mask of the destination IP addresses based on above destination subnet IP.

Gateway: This is the gateway IP address to which packets are to be forwarded.

Interface: Select the interface through which packets are to be forwarded.

Cost: This is the same meaning as Hop. This should usually be left at 1.

Static ARP

Go to Configuration/Advanced/Static Route.

IP Address: Fill in the IP address of the host computer that is sending the data packet.

MAC Address: Fill in the MAC address of the computer that the incoming data packets are to be forwarded.


152


Dynamic DNS

The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time. This dynamic IP address is the WAN IP address of the router, which is assigned to you by your ISP.

You will first need to register and establish an account with the Dynamic DNS provider using their website, for example http://www.dyndns.org/

There are more than 5 DDNS services supported.

Dynamic DNS:

 Disable: Check to disable the Dynamic DNS function.

 Enable: Check to enable the Dynamic DNS function. The following fields will be activated and required:

Dynamic DNS Server: Select the DDNS service you have established an account with.

Domain Name, Username and Password: Enter your registered domain name and your username and password for this service.

Period: Set the time period between updates, for the Router to exchange information with the DDNS server. In addition to updating periodically as per your settings, the router will perform an update when your dynamic IP address changes.


153


Device Management

The Device Management advanced configuration settings allow you to control your router’s security options and device monitoring features.

Device Host Name

Host Name: Give a name for it.

(The Host Name cannot be used with one word only. There are two words should be connected with a '.' at least.

Example:

Host Name: homegateway ==> Incorrect

Host Name: home.gateway or my.home.gateway ==> Correct)

Embedded Web Server ( 2 Management IP Accounts)

HTTP Port: This is the port number the router’s embedded web server (for web-based configuration) will use. The default value is the standard HTTP port, 80. Users may specify an alternative if, for example,

154


Billion BiPAC 7402NX(L) 802.11n 3G/ADSL2+ (VPN) Firewall Router they are running a web server on a PC within their LAN.

Management IP Address: You may specify an IP address allowed to logon and access the router’s web server. Setting the IP address to 0.0.0.0 will disable IP address restrictions, allowing users to login from any IP address.

Expire to auto-logout: Specify a time frame for the system to auto-logout the user’s configuration session.

For Example: User A changes HTTP port number to 100, specifies their own IP address of 192.168.1.55, and sets the logout time to be 100 seconds. The router will only allow User A access from the IP address

192.168.1.55 to logon to the Web GUI by typing: http://192.168.1.254:100 in their web browser. After 100 seconds, the device will automatically logout User A.

Universal Plug and Play (UPnP)

UPnP offers peer-to-peer network connectivity for PCs and other network devices, along with control and data transfer between devices. UPnP offers many advantages for users running NAT routers through

UPnP NAT Traversal, and on supported systems makes tasks such as port forwarding much easier by letting the application control the required settings, removing the need for the user to control advanced configuration of their device.

Both the user’s Operating System and the relevant application must support UPnP in addition to the router. Windows XP and Windows Me natively support UPnP (when the component is installed), and

Windows 98 users may install the Internet Connection Sharing client from Windows XP in order to support UPnP. Windows 2000 does not support UPnP.

 Disable: Check to disable the router’s UPnP functionality.

 Enable: Check to enable the router’s UPnP functionality.

UPnP Port: Its default setting is 2800. It is highly recommended for users to use this port value. If this value conflicts with other ports already being used you may wish to change the port.

SNMP Access Control (Software on a PC within the LAN is required in order to utilize this function) –

Simple Network Management Protocol.

 Disable: Check to disable the router’s SNMP functionality.

 Enable: Check to enable the router’s SNMP functionality.

SNMP V1 and V2:

Read Community: Specify a name to be identified as the Read Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, user obtains this IP address will be able to view the data.

Write Community: Specify a name to be identified as the Write Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, users from this IP address will be able to view and modify the data.

Trap Community: Specify a name to be identified as the Trap Community, and an IP address. This community string will be checked against the string entered in the configuration file. Once the string name is matched, users from this IP address will be sent SNMP Traps.

SNMP V3:

Specify a name and password for authentication. And define the access right from identified IP address.

Once the authentication has succeeded, users from this IP address will be able to view and modify the data.

155



SNMP Version: SNMPv2c and SNMPv3

SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the SNMPv2 security.

The "c" comes from the fact that SNMPv2c uses the SNMPv1 community string paradigm for "security", but is widely accepted as the SNMPv2 standard.

SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote monitoring.

Traps supported: Cold Start, Authentication Failure.

IGMP

IGMP, known as Internet Group Management Protocol, is used to management hosts from multicast group.

IGMP Proxy: Enables or disables the router’s IGMP Proxy.

Upstream Interface: When IGMP Proxy enabled, sets one of the router’s existing IP interfaces as the upstream interface; all other router interfaces are designated downstream interfaces.

IGMP Forward All: Enables/Disables your router’s ability to forward multicast traffic to ALL interfaces.

IGMP Snooping: Enables/Disables the IGMP Snoop functionality in the bridge. When the IGMP snoop functionality is enabled, all the attached bridge interfaces are designated as downstream interfaces.

MLD

MLD, short for Multicast Listener Discovery protocol, is a component if the Internet Protocol version

6(IPv6) suite. MLD is used by IPv6 to discover multicast listeners on a directly attached link, much as

IGMP used in IPv4. The protocol is embedded in ICMPv6 instead of using a separate protocol. MLDv1 is similar to IGMPv2 and MLDv2 is similar to IGMPv3.

MLD Proxy: check whether to enable this function. MLD (Multicast Listener Discovery Protocol) Proxy intercepts the MLD request from Clients and forwards it to the router after some dealings. Support MLDv1 and MLDv2.

Upstream Interface: When MLD Proxy enabled, sets one of the router’s existing IP interfaces as the upstream interface; all other router interfaces are designated downstream interfaces.

MLD Forward All: select enable to forward the multicast packets to all ports. If select disable, the multicast packets will be forwarded to ports set according to the MLD Snooping below.

MLD Snooping: similar to IGMP snooping, listens in on the MLD conversation between hosts and

158
