For use the router properly, it is necessary for you to change the password of web configuration for security and adjust primary basic settings.

This chapter explains how to setup a password for an administrator and how to adjust basic settings for accessing Internet successfully. Be aware that only the administrator can change the router configuration.

22..11 CChhaannggiinngg PPaasssswwoorrdd

For security reasons, it is strongly recommend that you set the administrator password for the router. During the first setup, the router requires no password. If no password is configured, the router will be open to any user in the LAN or the Internet, and users can log into the router unlimitedly and change the settings.

To change the password for this device, you have to access into the web browse with default password first.

1. Make sure your computer connects to the router correctly.

Notice: You may either simply set up your computer to get IP dynamically from the router or set up the IP address of the computer to be the same subnet as the default IP address of Vigor router 192.168.1.1. For the detailed information, please refer to the later section - Trouble Shooting of this guide.

In the Quick Start Wizard, you can configure the router to access the Internet with different protocol/modes such as PPPoE, PPTP, L2TP, Static IP or DHCP. The router supports the DSL WAN interface for Internet access.

22..22..22 PPPPPPooEE

PPPoE stands for Point-to-Point Protocol over Ethernet. It relies on two widely accepted standards: PPP and Ethernet. It connects users through an Ethernet to the Internet with a common broadband medium, such as a single DSL line, wireless device or cable modem. All the users over the Ethernet can share a common connection. And the PPPoA stands for Point-to-Point Protocol over ATM. PPPoA uses the PPP dial-up protocol with ATM as the transport.

Vigor2900 Series User’s Guide

PPPoE is used for most of DSL modem users. All local users can share one PPPoE connection for accessing the Internet. Your service provider will provide you information about user name, password, and authentication mode.

If your ISP provides you the PPPoE connection, please select PPPoE for this router. The following page will be shown:

The most generic function of Vigor router is NAT. It creates a private subnet of your own. As mentioned previously, the router will talk to other public hosts on the Internet by using public IP address and talking to local hosts by using its private IP address. What NAT does is to translate the packets from public IP address to private IP address to forward the right packets to the right host and vice versa. Besides, Vigor router has a built-in DHCP server that assigns private IP address to each local host. See the following diagram for a briefly understanding.

In some special case, you may have a public IP subnet from your ISP such as

220.135.240.0/24. This means that you can set up a public subnet or call second subnet that each host is equipped with a public IP address. As a part of the public subnet, the Vigor router

Vigor2900 Series User’s Guide

will serve for IP routing to help hosts in the public subnet to communicate with other public hosts or servers outside. Therefore, the router should be set as the gateway for public hosts.

WWhhaatt iiss RRoouuttiinngg IInnffoorrmmaattiioonn PPrroottooccooll ((RRIIPP))

Vigor router will exchange routing information with neighboring routers using the RIP to accomplish IP routing. This allows users to change the information of the router such as IP address and the routers will automatically inform for each other.

WWhhaatt iiss SSttaattiicc RRoouuttee

When you have several subnets in your LAN, sometimes a more effective and quicker way for connection is the Static routes function rather than other method. You may simply set rules to forward data from one specified subnet to another specified subnet without the presence of RIP.

2nd DHCP Server You can configure the router to serve as a DHCP server for the 2nd

subnet.

Start IP Address: Enter a value of the IP address pool for the DHCP server to start with when issuing IP addresses. If the 2nd IP address of your router is 220.135.240.1, the starting IP address must be

220.135.240.2 or greater, but smaller than 220.135.240.254.

IP Pool Counts: Enter the number of IP addresses in the pool. The maximum is 10. For example, if you type 3 and the 2nd IP address of your router is 220.135.240.1, the range of IP address by the DHCP server will be from 220.135.240.2 to 220.135.240.4.

MAC Address: Enter the MAC Address of the host one by one and click Add to create a list of hosts to be assigned, deleted or edited IP address from above pool. Set a list of MAC Address for 2 server will help router to assign the correct IP address of the correct subnet to the correct host. So those hosts in 2 IP address belonging to 1

1st Subnet - Select the router to change the RIP information of the 1st subnet with neighboring routers. 2nd Subnet - Select the router to change the RIP information of the 2nd subnet with neighboring routers.

DHCP stands for Dynamic Host Configuration Protocol. The router by factory default acts a DHCP server for your network so it automatically dispatch related IP settings to any local user configured as a DHCP client. It is highly recommended that you leave the router enabled as a DHCP server if you do not have a

DHCP server for your network.

If you want to use another DHCP server in the network other than

the Vigor Router’s, you can let Relay Agent help you to redirect the DHCP request to the specified location. Enable Server - Let the router assign IP address to every host in the LAN. Disable Server – Let you manually assign IP address to every host in the LAN.

Relay Agent – (1

subnet/2nd subnet) Specify which subnet that

DHCP server is located the relay agent should redirect the DHCP request to. Start IP Address - Enter a value of the IP address pool for the DHCP server to start with when issuing IP addresses. If the 1st IP address of your router is 192.168.1.1, the starting IP address must be

192.168.1.2 or greater, but smaller than 192.168.1.254. IP Pool Counts - Enter the maximum number of PCs that you want the DHCP server to assign IP addresses to. The default is 50 and the maximum is 253. Gateway IP Address - Enter a value of the gateway IP address for the DHCP server. The value is usually as same as the 1st IP address of the router, which means the router is the default gateway. DHCP Server IP Address for Relay Agent - Set the IP address of the DHCP server you are going to use so the Relay Agent can help to forward the DHCP request to the DHCP server.

DNS Server Configuration

DNS stands for Domain Name System. Every Internet host must have a unique IP address, also they may have a human-friendly, easy to remember name such as www.yahoo.com. The DNS server converts the user-friendly name into its equivalent IP address.

Primary IP Address -You must specify a DNS server IP address

here because your ISP should provide you with usually more than one DNS Server. If your ISP does not provide it, the router will automatically apply default DNS Server IP address: 194.109.6.66 to this field. Secondary IP Address - You can specify secondary DNS server IP address here because your ISP often provides you more than one DNS Server. If your ISP does not provide it, the router will automatically apply default secondary DNS Server IP address:

194.98.0.1 to this field. The default DNS Server IP address can be found via Online Status:

If both the Primary IP and Secondary IP Address fields are left empty, the router will assign its own IP address to local users as a DNS proxy server and maintain a DNS cache.

If the IP address of a domain name is already in the DNS cache, the router will resolve the domain name immediately. Otherwise, the router forwards the DNS query packet to the external DNS server by establishing a WAN (e.g. DSL/Cable) connection.

There are two common scenarios of LAN settings that stated in Chapter 4. For the configuration examples, please refer to that chapter to get more information for your necessity.

Note: The following is available for Vigor2900VGi/Vi only.

ISDN Port Click Enable to open the ISDN port and Disable to close

it.

Country Code For proper operation on your local ISDN network, you

should choose the correct country code.

Own Number Enter your ISDN number. Every outgoing call will carry

the number to the receiver.

MSN Numbers for the Router MSN Numbers mean that the router is able to accept only

number-matched incoming calls. In addition, MSN services should be supported by local ISDN network provider. The router provides three fields for MSN numbers. Note that MSN services must be acquired from your local telecommunication operators. By default, MSN function is disabled. If you leave the fields blank, all incoming calls will be accepted without number matching.

Blocked MSN Numbers for the router

For example, DrayTek provides the Remote Activation (refer to section 3.2) feature for the teleworkers who wish to dial in the head office over the ISDN. With this feature, teleworkers can make a phone call to the router at the head office and ask the router to dial up the ISP. As a result, the teleworkers can be authorized with their office accounts to utilize ISDN dial-up services and both sides can thus engage in secure communication over the LAN-to-LAN ISDN.

Enter the specified MSN number into the fields to prevent the router from dialing the specific MSN number.

The ISDN interface of Vigor2900VGi and Vigor2900Vi routers supports the VTA (Virtual Terminal Adapter, please refer to section 2.8) feature. VTA is actually a “CAPI” software,

Real-time Hardware Encryption: Vigor Router is equipped with a hardware AES encryption engine so it can apply the highest protection to your data without influencing user experience.

Complete Security Standard Selection: To ensure the security and privacy of your wireless communication, we provide several prevailing standards on market.

WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via radio using either a 64-bit or128-bit key. Usually access point will preset a set of four keys and it will communicate with each station using only one out of the four keys.

WPA(Wi-Fi Protected Access), the most dominating security mechanism in industry, is separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK), and WPA-Enterprise or called WPA/802.1x.

In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies AES. The WPA-Enterprise combines not only encryption but also authentication.

Since WEP has been proved vulnerable, you may consider using WPA for the most secure connection. You should select the appropriate security mechanism according to your needs. No matter which security suite you select, they all will enhance the over-the-air data protection and /or privacy on your wireless network. The Vigor wireless router is very flexible and can support multiple secure connections with both WEP and WPA at the same time.

Separate the Wireless and the Wired LAN- WLAN Isolation enables you to isolate your wireless LAN from wired LAN for either quarantine or limit access reasons. To isolate means neither of the parties can access each other. To elaborate an example for business use, you may set up a wireless LAN for visitors only so they can connect to Internet without hassle of the confidential information leakage. For a more flexible deployment, you may add a filter of MAC address to isolate single user’s access from wired LAN.

IP means Internet Protocol. Every device in an IP-based Network including routers, print server, and host PCs, needs an IP address to identify its location on the network. To avoid address conflicts, IP addresses are publicly registered with the Network Information Centre (NIC). Having a unique IP address is mandatory for those devices participated in the public network but not in the private TCP/IP local area networks (LANs), such as host PCs under the management of a router since they do not need to be accessed by the public. Hence, the NIC has reserved certain addresses that will never be registered publicly. These are known as private IP addresses, and are listed in the following ranges:

From 10.0.0.0 to 10.255.255.255 From 172.16.0.0 to 172.31.255.255 From 192.168.0.0 to 192.168.255.255

As the router plays a role to manage and further protect its LAN, it interconnects groups of host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the Vigor router. The router itself will also use the default private IP address: 192.168.1.1 to communicate with the local hosts. Meanwhile, Vigor router will communicate with other network devices through a public IP address. When the data flow passing through, the Network Address Translation (NAT) function of the router will dedicate to translate public/private addresses, and the packets will be delivered to the correct host PC in the local area network. Thus, all the host PCs can share a common Internet connection.

To acquire a public IP address from your ISP for Vigor router as a customer premises equipment, there are three common protocols: Point to Point Protocol over Ethernet (PPPoE), PPPoA and MPoA. Multi-PVC is provided for more advanced setup of the above.

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is required for bridging customer premises equipment (CPE). Point to Point Protocol over Ethernet (PPPoE) connects a network of hosts via an access device to a remote access concentrator or aggregation concentrator. This implementation provides users with significant ease of use. Meanwhile it provides access control, billing, and type of service according to user requirement.

When a router begins to connect to your ISP, a serial of discovery process will occur to ask for a connection. Then a session will be created. Your user ID and password is authenticated via PAP or CHAP with RADIUS authentication system. And your IP address, DNS server, and other related information will usually be assigned by your ISP.

In the Quick Setup field, you can configure the router for different connection types, such as ISDN, PPPoE, PPTP, Dynamic/Static IP or Broadband Access with ISDN dial backup. Note that the types of ISDN and Broadband Access with ISDN dial backup are available only to Vigor routers with the ISDN interface (e.g. Vigor2900VGi).

Virtual TA means the local hosts or PCs in the network that uses popular CAPI-based software such as RVS-COM or BVRP to access the router as a local ISDN TA for sending or receiving FAX messages over the ISDN line. Basically, it is a client/server network model. The built-in Virtual TA server handles the establishment and release of connections. The Virtual TA client, which is installed on the local hosts or PCs, creates a CAPI-based driver to relay all CAPI messages between the applications and the router CAPI module. Before describing the configuration of Virtual TA in the Vigor routers, please notice the following limitations.

z The Virtual TA client only supports Microsoft

platforms.

Vigor2900 Series User’s Guide

Windows 95 OSR2.1/98/98SE/Me/2000

z The Virtual TA client only supports the CAPI 2.0 protocol and has no built-in FAX

engine.

z One ISDN BRI interface has two B channels. The maximum number of active clients is

also two.

z Before you configure the Virtual TA, you must set the correct country code.

As depicted in the above application scenario, the Virtual TA client can make an outgoing call or accept an incoming call to/from a peer FAX machine or ISDN TA, etc.

Before you configure the Virtual TA (Remote CAPI) Setup, please install the virtual TA client first. Simply insert the CD bundled with your Vigor router, or directly double-click one of the installer files. In which Vsetup95.exe is for Windows 95 OSR2.1 or higher; Vsetup98.exe is for Windows 98, 98SE and Me; and Vsetup2k.exe is for Windows 2000. Follow the on-screen instructions of the installer. The last step will ask you to restart your computer. Click OK to restart your computer.

After the computer restarts, you will see a VT icon in the taskbar (usually in the bottom-right of the screen, near the clock) as shown below.

When the icon text is GREEN, the Virtual TA client is connected to the Virtual TA server and you can launch your CAPI-based software to use the client to access the router. Please read your software user guide for detailed configuration. If the icon text is RED, it means the client has lost the connection to the server. In such condition, please check the physical Ethernet connection.

Next, click the Virtual TA (Remote CAPI) Setup link in the Quick Setup group to configure the V irtual TA features.

Since the Virtual TA application is a client/server network model, you must configure it on both ends to run properly your Virtual TA application.

By default, the Virtual TA server is enabled and the Username/Password fields are left blank. Any Virtual TA client may login to the server. Once a single Username/Password field has been filled in, the Virtual TA server will only allow clients with a valid Username/Password to login. The screen of Virtual TA configuration is presented below.

If you have applied to an MSN number service, the Virtual TA server can assign which client has the specified MSN number. When an incoming call arrives, the server will inform the appropriate client. Now we set an example to describe the configuration of the MSN number.

Suppose that you could assign the MSN number 123 to the client “alan”.

Type the specified MSN number in the CAPI-based software. When the Virtual TA server sends an alert signal to the specified Virtual TA client, the CAPI-based software will also receive the action, the software will not accept the incoming call.

The ISP often provides you with a dynamic IP address when you connect to the Internet via your ISP. It means that the public IP address assigned to your router changes each time you access the Internet. The Dynamic DNS feature lets you assign a domain name to a dynamic WAN IP address. It allows the router to update its online WAN IP address mappings on the specified Dynamic DNS server. Once the router is online, you will be able to use the registered domain name to access the router or internal virtual servers from the Internet. It is particularly helpful if you host a web server, FTP server, or other server behind the router.

Before you use the Dynamic DNS feature, you have to apply for free DDNS service to the DDNS service providers. The router provides up to three accounts from three different DDNS service providers. Basically, Vigor routers are compatible with the DDNS services supplied by most popular DDNS service providers such as www.dyndns.org, www.no-ip.com, www.dtdns.com, www.changeip.com, www.dynamic- nameserver.com. You should visit their websites to register your own domain name for the router.

Some applications require that the router (only for the i models) be remotely activated, or be able to dial up to the ISP via the ISDN interface. Vigor routers provide this feature which allows you to make a phone call to the router and then ask it to dial up to the ISP. Accordingly, you can access your remote network to retrieve resources. Of course, you should have a fixed IP address and expose some internal network resources to the outside world, such as FTP, WWW and so on.

Note: Call Control and PPP/MP are only available for the models of Vigor2900VGi and Vigor2900Vi equipped with the ISDN interface.

Click Call Control and PPP/MP Setup from Advanced Setup group.

Note: Please set Dialing to a Single ISP first before configuring this web page.

Dial Retry It specifies the dial retry counts per triggered packet. A

triggered packet is the packet whose destination is outside the local network. The default setting is no dial retry. If set to 5, for each triggered packet, the router will dial 5 times until it is connected to the ISP or remote access router.

Dial Delay Interval It specifies the interval between dialup retries. By default, the

interval is 0 second.

Remote Activation It specifies a phone number in the Remote Activation field to

enable the remote activation function. If the router accepts a call from the number 12345678, it will terminate the incoming call immediately and dial to the ISP.

Link Type Because ISDN has two B channels (64Kbps/per channel), you

can specify whether you would like to have single B channel, two B channels or BOD (Bandwidth on Demand). Four options are available: Link Disable, Dialup 64Kbps, Dialup 128Kbps, Dialup BOD.

Vigor2900 Series User’s Guide

PPP Authentication It specifies the PPP authentication method for PPP/MP

connections. Normally you can set it to PAP/CHAP for better compatibility.

TCP Header Compression VJ Compression - It is used for TCP/IP protocol header

compression. Normally it is set to None to improve bandwidth utilization.

Idle Timeout Because our IDSN link type is “Dial On Demand”, the

connection will be initiated only when needed.

High Water Mark and High Water Time

Low Water Mark and Low Water Time

BOD stands for bandwidth-on-demand for Multiple-Link PPP (ML-PPP or MP). High Water Mark/ High Water Time/ Low Water Mark/Low Water Time parameters are applied when you set the Link Type to Dialup BOD. The ISDN usually uses one B channel to access the Internet or remote network when you choose the Dialup BOD link type. The router will use the parameters here to decide on when you activate/drop the additional B channel. Note that cps (characters-per-second) measures the total link utilization.

These parameters specify the situation in which the second channel will be activated. With the first connected channel, if its utilization exceeds the High Water Mark and such a channel is being used over the High Water Time, the additional channel will be activated. Thus, the total link speed will be 128kbps (two B channels).

These parameters specify the situation in which the second channel will be dropped. In terms of the two B channels, if their utilization is under the Low Water Mark and these two channels are being used over the High Water Time, the additional channel will be dropped. As a result, the total link speed will be 64kbps (one B channel).

Note: If you are not sure whether your ISP can support BOD and/or ML-PPP’s features, please seek assistance from your ISP, local dealers or our website: support@draytek.com.

The Vigor router has a built-in real time clock which can update itself manually or automatically by means of Network Time Protocols (NTP). As a result, you can not only schedule the router to dialup to the Internet at a specified time, but also restrict Internet access to certain hours so that users can connect to the Internet only during certain hours, say, business hours. The schedule is also applicable to other functions.

You have to set your time before set schedule. In the System Management group, select Time and Date to open the time setup page, press Inquire Time button to set the Vigor router’s clock to current time of your PC. The clock will reset once if you power down or reset the router. There is another way to set up time. You can inquiry an NTP server (a time server) on the Internet to synchronize the router’s clock.

Usually, the router serves as an NAT (Network Address Translation) router. NAT is a mechanism that one or more private IP addresses can be mapped into a single public one. Public IP address is usually assigned by your ISP, for which you may get charged. Private IP addresses are recognized only among internal hosts.

When the outgoing packets destined to some public server on the Internet reach the NAT router, the router will change its source address into the public IP address of the router, select the available public port, and then forward it. At the same time, the router shall list an entry in a table to memorize this address/port-mapping relationship. When the public server response, the incoming traffic, of course, is destined to the router’s public IP address and the router will do the inversion based on its table. Therefore, the internal host can communicate with external host smoothly.

The benefit of the NAT includes: z Save cost on applying public IP address and apply efficient usage of IP address.

NAT allows the internal IP addresses of local hosts to be translated into one public IP address, thus you can have only one IP address on behalf of the entire internal hosts.

z Enhance security of the internal network by obscuring the IP address. There are

many attacks aiming victims based on the IP address. Since the attacker cannot be aware of any private IP addresses, the NAT function can protect the internal network.

Vigor2900 Series User’s Guide

On NAT page, you will see the private IP address defined in RFC-1918. Usually we use the 192.168.1.0/24 subnet for the router. As stated before, the NAT facility can map one or more IP addresses and/or service ports into different specified services. In other words, the NAT function can be achieved by using port mapping methods.

Click NAT Setup on the Advanced Setup page. The setting items for NAT will be shown as below.

Port Redirection is usually set up for server related service inside the local network (LAN), such as web servers, FTP servers, E-mail servers etc. Most of the case, you need a public IP address for each server and this public IP address/domain name are recognized by all users. Since the server is actually located inside the LAN, the network well protected by NAT of the router, and identified by its private IP address/port, the goal of Port Redirection function is to forward all access request with public IP address from external users to the mapping private IP address/port of the server.

The port redirection can only apply to incoming traffic. To use this function, please go to NAT page and choose Port Redirection web page. The

Port Redirection Table provides 10 port-mapping entries for the internal hosts.

Vigor2900 Series User’s Guide

Service Name Enter the description of the specific network service. Protocol Select the transport layer protocol (TCP or UDP). Public Port Specify which port can be redirected to the specified Private IP and

Port of the internal host. Private IP Specify the private IP address of the internal host providing the

service. Private Port Specify the private port number of the service offered by the internal

host. Active Check this box to activate the port-mapping entry you have defined. Note that the router has its own built-in services (servers) such as Telnet, HTTP and FTP etc.

Since the common port numbers of these services (servers) are all the same, you may need to reset the router in order to avoid confliction.

For example, the built-in web configurator in the router is with default port 80, which may conflict with the web server in the local network, http://192.168.1.13:80. Therefore, you need to change the router’s http port to any one other than the default port 80 to avoid conflict, such as 8080. This can be set by the Management Setup in the System Management group. You then will access the admin screen of by suffixing the IP address with 8080, e.g., http://192.168.1.1:8080 instead of port 80.

As mentioned above, Port Redirection can redirect incoming TCP/UDP or other traffic on particular ports to the specific private IP address/port of host in the LAN. However, other IP protocols, for example Protocols 50 (ESP) and 51 (AH), do not travel on a fixed port. Vigor router provides a facility DMZ Host that maps ALL unsolicited data on any protocol to a single host in the LAN. Regular web surfing and other such Internet activities from other clients will continue to work without inappropriate interruption. DMZ Host allows a defined internal user to be totally exposed to the Internet, which usually helps some special applications such as Netmeeting or Internet Games etc.

While the broadband users demand more bandwidth for multimedia, interactive applications, or distance learning, security has been always the most concerned. The firewall of the Vigor router helps to protect your local network against attack from unauthorized outsiders. It also restricts users in the local network from accessing the Internet. Furthermore, it can filter out specific packets that trigger the router to build an unwanted outgoing connection.

The most basic security concept is to set user name and password while you install your router. The administrator login will prevent unauthorized access to the router configuration from your router.

The users on the LAN are provided with secured protection by the following firewall facilities:

z User-configurable IP filter (Call Filter/ Data Filter). z Stateful Packet Inspection (SPI): tracks packets and denies unsolicited incoming data z Selectable Denial of Service (DoS) /Distributed DoS (DDoS) attacks protection z URL Content Filter

IIPP FFiilltteerrss

Depending on whether there is an existing Internet connection, or in other words “the WAN link status is up or down”, the IP filter architecture categorizes traffic into two: Call Filter and Data Filter.

z Call Filter - When there is no existing Internet connection, Call Filter is applied to all

traffic, all of which should be outgoing. It will check packets according to the filter rules. If legal, the packet will pass. Then the router shall “initiate a call” to build the Internet connection and send the packet to Internet.

Vigor2900 Series User’s Guide

z Data Filter - When there is an existing Internet connection, Data Filter is applied to

incoming and outgoing traffic. It will check packets according to the filter rules. If legal, the packet will pass the router.

The following illustrations are flow charts explaining how router will treat incoming traffic and outgoing traffic respectively.

Stateful inspection is a firewall architecture that works at the network layer. Unlike legacy static packet filtering, which examines a packet based on the information in its header, stateful inspection builds up a state machine to track each connection traversing all interfaces of the firewall and makes sure they are valid. The stateful firewall of Vigor router not just examine the header information also monitor the state of the connection.

As the popularity of all kinds of instant messenger application arises, communication cannot become much easier. Nevertheless, while some industry may leverage this as a great tool to connect with their customers, some industry may take reserve attitude in order to reduce employee misusage during office hour or prevent unknown security leak. It is similar situation for corporation towards peer-to-peer applications since file-sharing can be convenient but insecure at the same time. To address these needs, we provide IM and P2P blocking functionality.

The DoS Defense functionality helps you to detect and mitigate the DoS attack. The attacks are usually categorized into two types, the flooding-type attacks and the vulnerability attacks. The flooding-type attacks will attempt to exhaust all your system's resource while the vulnerability attacks will try to paralyze the system by offending the vulnerabilities of the protocol or operation system.

The DoS Defense function enables the Vigor router to inspect every packet based on the attack signature database. Any malicious packet that might duplicate itself to paralyze the host in the secure LAN will be strictly blocked and a Syslog message will be sent as warning, if you set up Syslog server.

Also the Vigor router monitors the traffic. Any abnormal traffic flow violating the pre-defined parameter, such as the number of thresholds, is identified as an attack and the Vigor router will activate its defense mechanism to mitigate in a real-time manner.

The below shows the attack types that DoS/DDoS defense function can detect:

1. SYN flood attack

2. UDP flood attack

3. ICMP flood attack

4. TCP Flag scan

5. Trace route

6. IP options

7. Unknown protocol

8. Land attack

9. Smurf attack

To provide an appropriate cyberspace to users, Vigor router equips with URL Content Filter not only to limit illegal traffic from/to the inappropriate web sites but also prohibit other web feature where malicious code may conceal.

Once a user type in or click on an URL with objectionable keywords, URL keyword blocking facility will decline the HTTP request to that web page thus can limit user’s access to the website. You may imagine URL Content Filter as a well-trained convenience-store clerk who won’t sell adult magazines to teenagers. At office, URL Content Filter can also provide a job-related only environment hence to increase the employee work efficiency. How can URL Content Filter work better than traditional firewall in the field of filtering? Because it checks the URL strings or some of HTTP data hiding in the payload of TCP packets while legacy firewall inspects packets based on the fields of TCP/IP headers only.

On the other hand, Vigor router can prevent user from accidentally downloading malicious codes from web pages. It’s very common that malicious codes conceal in the executable objects, such as ActiveX, Java Applet, compressed files, and other executable files. Once downloading these types of files from websites, you may risk bringing threat to your system. For example, an ActiveX control object is usually used for providing interactive web feature. If malicious code hides inside, it may occupy user’s system.

We all know that the content on the Internet just like other types of media may be inappropriate sometimes. As a responsible parent or employer, you should protect those in your trust against the hazards. With Web filtering service of the Vigor router, you can protect your business from common primary threats, such as productivity, legal liability, network and security threats. For parents, you can protect your children from viewing adult websites or chat rooms.

Once you have activated your Web Filtering service in Vigor router and chosen the categories of website you wish to restrict, each URL address requested (e.g.www.bbc.co.uk) will be checked against our server database, powered by SurfControl. The database covering over 70 languages and 200 countries, over 1 billion Web pages divided into 40 easy-to-understand categories. This database is updated as frequent as daily by a global team of Internet researchers. The server will look up the URL and return a category to your router. Your Vigor router will then decide whether to allow access to this site according to the categories you have selected. Please note that this action will not introduce any delay in your Web surfing because each of multiple load balanced database servers can handle millions of requests for categorization.

Dial-In PPP Authentication

PAP Only - Select this option to force the router to

authenticate dial-in users with the PAP protocol. PAP or CHAP - Selecting this option means the router will attempt to authenticate dial-in users with the CHAP protocol first. If the dial-in user does not support this protocol, it will fall back to use the PAP protocol for authentication.

Dial-In PPP Encryption ( MPPE)

Mutual Authentication (PAP)

This option represents that the MPPE encryption method will be optionally employed in the router for the remote dial-in user. If the remote dial-in user does not support the MPPE encryption algorithm, the router will transmit “no MPPE encrypted packets”. Otherwise, the MPPE encryption scheme will be used to encrypt the data.

Require MPPE (40/128bits) - Selecting this option will force the router to encrypt packets by using the MPPE encryption algorithm. In addition, the remote dial-in user will use 40-bit to perform encryption prior to using 128-bit for encryption. In other words, if 1280-bit MPPE encryption method is not available, then 40-bit encryption scheme will be applied to encrypt the data. Maximum MPPE - This option indicates that the router will use the MPPE encryption scheme with maximum bits (128 bits) to encrypt the data.

The Mutual Authentication function is mainly used to communicate with other routers or clients who need bi-directional authentication in order to provide stronger security, for example, Cisco routers. So you should enable this function when your peer router requires mutual authentication. You should further specify the User Name and Password of the mutual authentication peer.

In IPSec General Setup, there are two major parts of configuration. There are two phases of IPSec. ¾ Phase 1: negotiation of IKE parameters including encryption, hash, Diffie-Hellman

parameter values, and lifetime to protect the following IKE exchange, authentication of both peers using either a Pre-Shared Key or Digital Signature (x.509). The peer that starts the negotiation proposes all its policies to the remote peer and then remote peer tries to find a highest-priority match with its policies. Eventually to set up a secure tunnel for IKE Phase 2.

¾ Phase 2: negotiation IPSec security methods including Authentication Header (AH) or

Encapsulating Security Payload (ESP) for the following IKE exchange and mutual examination of the secure tunnel establishment.

There are two encapsulation methods used in IPSec, Transport and Tunnel. The Transport mode will add the AH/ESP payload and use original IP header to encapsulate the data payload only. It can just apply to local packet, e.g., L2TP over IPSec. The Tunnel mode will not only add the AH/ESP payload but also use a new IP header (Tunneled IP header) to encapsulate the whole original IP packet.

Authentication Header (AH) provides data authentication and integrity for IP packets passed between VPN peers. This is achieved by a keyed one-way hash function to the packet to create a message digest. This digest will be put in the AH and transmitted along with packets. On the receiving side, the peer will perform the same one-way hash on the packet and compare the value with the one in the AH it receives.

Encapsulating Security Payload (ESP) is a security protocol that provides data confidentiality and protection with optional authentication and replay detection service.

IKE Authentication Method This usually applies to those are remote dial-in user or node

(LAN-to-LAN) which uses dynamic IP address and IPSec-related VPN connections such as L2TP over IPSec and IPSec tunnel. Pre-Shared Key -Currently only support Pre-Shared Key authentication. Specify a key for IKE authentication. Re-type Pre-Shared Key -Confirm the pre-shared key.

IPSec Security Method Medium - Authentication Header (AH) means data will be

authenticated, but not be encrypted. By default, this option is active. High - Encapsulating Security Payload (ESP) means payload
