standard, 6200 series make full use of the advanced G.SHDSL.bis technology to offer data transmission rates of up

to 5.696Mbps in 2-wire mode, 11.392Mbps in 4-wire mode and 22.784Mbps in 8-wire mode.

6200 series VPN Router is integrated high-end Bridging/Routing capabilities with advanced functions of Multi-DMZ,

Virtual Server mapping, and VPN pass-through. Because of rapid growth of network, virtual LAN has become one of

the major new areas in internetworking industry. 6200 support port-based VLAN and IEEE 802.1q VLAN over ATM

network.

With always on connection that DSL features, 6200 series VPN routers provide advanced firewall with SPI (Stateful

Packet Inspection) and DoS protection, serving as a powerful firewall to protect from outside intruders of secure

connection. It also supports IP precedence to classify and prioritize types of IP traffic. In additional, its VPN feature

supports data transmission over the Internet by data encryption/decryption between two sites. VPNs feature allows

replacing a private leased line to minimize the expense among global inter-connection.

Not only the much higher bandwidth than convention symmetric digital subscriber loop, 6200 series also provide

the network administrators tool of Quality of Service (QoS) to allocate network resources effectively. By classify the

priority of services, the functions of bandwidth management increases efficiency and productivity on specific demands

such as VoIP, video streaming, video-conferencing or interactive game applications to guarantee all the application get

the deserved service quality.

“Quick Setup” function guides users to setup their VPN routers step by step. This VPN Router can be set as a bridge

or a router. The following sections show how to setup a bridge mode or a router mode.

33..33..11..

SSyysstteemm MMooddee

“System Mode” allows users to decide this VPN router should be a bridge device or a router device.

“Router mode” is when the DSL modem performs all the functions that allow you to connect to the Internet which include: all the technical settings (VCI, encapsulation, etc.) and the VPN router also connects to the ISP with your username and password. You can basically just connect to your computer.

“Bridge mode”, on the other hand, allows some external device, for example, your computer or a separate router, to do the ISP connection, etc. In bridge mode, all the VPN router does is remembering your VCI, VPI and encapsulation settings. The ISP information and IP address assigned is controlled b your separate router or computer in PPP mode.

33..33..11..11

BBrriiddggee MMooddee

Click on “Bridge” to set this VPN router as a bridge device.

Once a user chooses “Bridge” mode, two more setups will be shown: “WAN ENCAP” and “WAN VPI/VCI”.

WAN ENCAP

There are two encapsulation types: VC-Mux (Virtual Circuit Multiplexing) and LLC(Logical Link Control). VC-MUX and LLC are two mechanisms for identifying the protocol carried in ATM Adaptation Layer 5 (AAL5) frames.

WAN VPI/VIC

There is an unique VPI and VCI value for Internet connection supported by ISP. The range of VIP is from 0 to 255, and VCI is from 0 to 65535.

33..33..11..22

In the last section of this page, you can define the IP address of the default gateway and the size of MTU.

QQooSS CCllaassss

The router supports UBR, CBR, VBR-rt and VBR-nrt.

UBR (Unspecified Bit Rate) is the simplest service provided by ATM networks. There is no guarantee of anything. It is a

primary service used for transferring Internet traffic over the ATM network.

CBR (Constant Bit Rate) is used by connections that requires a static amount of bandwidth that is avilable during the

connection life time. This bandwidth is characterized by Peak Cell Rate (PCR). Based on the PCR of the CBR traffic,

specific cell slots are assigned for the VC in the schedule table. The ATM always sends a signle cell during the CBR

connection’s assigned cell slot.

VBR-rt (Varible Bit Rate real-time) is intended for real-time applications, such as compressed voice over IP and video

comferencing, that require tightly constrained delays and delay variation. VBR-rt is characterized by a peak cell rate

(PCR), substained cell rate (SCR), and maximun burst rate (MBR).

VBR-nrt (Varible Bit Rate non-real-time) is intended for non-real-time applications, such as FTP, e-mail and browsing.

QQooSS PPCCRR

PCR (Peak Cell Rate) in kbps: The maximum rate at which you expect to transmit data, voice and video. Consider PCR

and MBS as a menas of reducing lantency, not increasing bandwidth.

QQooSS SSCCRR

SCR (Substained Cell Rate): The sustained rate at which you expect to transmit data, voice and video. Consider SCR to

be the true bandwidth of a VC and not the lone-term average traffic rate.

33..44..44.. DDNNSS

The Domain Name Service (DNS) is a system designed to allow the identification of Internet servers to be based on names rather than IP addresses. Because Internet communication is based on IP addresses, all names must be translated into an IP address. This is the purpose of a Domain Name Server.

33..44..55.. DDHHCCPP

Dynamic Host Configuration Protocol (DHCP) is a communication protocol that lets network administrators to manage

centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network. Using the

Internet Protocol, each machine that can connect to the Internet needs a unique IP address. When an organization sets

up its computer users with a connection to the Internet, an IP address must be assigned to each machine.

Without DHCP, the IP address must be entered manually at each computer. If computers move to another location in another part of the network, a new IP address must be entered. DHCP lets a network administrator to supervise and distribute IP addresses from a central point and automatically sends a new IP address when a computer is plugged into a different place in the network.

33..44..66.. NNAATT

NAT (Network Address Translation) is the translation of an Internet Protocol address (IP address) used within one

network to a different IP address known within another network. One network is designated the inside network and

the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP

addresses and reverse the global IP addresses of incoming packets back into local IP addresses. This ensure security

since each outgoing or incoming request must go through a translation process, that also offers the opportunity to

qualify or authenticate the request or match it to a previous request. NAT also conserves on the number of global IP

addresses that a company needs and lets the company to use a single IP address of its communication in the Internet

world.

SSTTPP

STP (Spanning-Tree Protocol) defined in the IEEE 802.1D, is a link management protocol that provides path redundancy

while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path

can exist between two stations.

Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the

potential exists for duplication of messages. When loops occur, some switches see stations appear on both sides of the

switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.

To provide path redundancy, Spanning-Tree Protocol defines a tree that spans all switches in an extended network.

Spanning-Tree Protocol forces certain redundant data paths into a standby (blocked) state. If one network segment in

the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree

algorithm reconfigures the spanning-tree topology and reestablishes the link by activating the standby path.

Spanning-Tree Protocol operation is transparent to end stations, which are unaware whether they are connected to a

single LAN segment or a switched LAN of multiple segments.

VVLLAANN

VLAN is for Bridge mode only.

VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Devices

on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot

directly talk to or hear from devices that are not in the same group.

With MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the subscribers.

When properly configured, VLAN prevents one subscriber from accessing the network resources of another on the

same LAN.

VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast

domain. In traditional switched environments, all broadcast packets go to each every individual port. With VLAN, all

broadcasts are confined to a specific broadcast domain.

User can choose three types of VLAN: 802.1Q Tag-Based VLAN and Port-Based VLAN. You can also set Disable the VLAN

function.

The VLAN Setup screen changes depending on whether you choose 802.1Q Tag-Based VLAN type and Port Based VLAN

types in this screen.

The IEEE 802.1Q defines the operation of VLAN bridges that permit the definition, operation, and administration of

VLAN topologies within a bridged LAN infrastructure.

880022..11QQ TTaagg--BBaasseedd VVLLAANN

Click the 802.1Q Tag-Based VLAN to configure the VPN Router.

In 802.1q, the VLAN information is written into the Ethernet packet itself. Each packet carries a VLAN ID (Virtual LAN

ID), called a tag. This allows VLANs to be configured across multiple switches. Note that it’s possible for VLAN tags to

be stripped by H/W and/or S/W.

When using 802.1q, four bytes are added to the Ethernet frame, of which 12 bits are used for the VLAN ID.

Theoretically, there can be up to 4096 VLANs per network.

An Ethernet packet that contains a VLAN ID is called a tagged packet. Conversely, an Ethernet packet with no VLAN ID

is called an untagged packet. Typically all packets leave untagged, unless tagged by the adapter prior to arriving at the

switch port.

Egress and Ingress Rules:

Egress rules determine which frames can be transmitted out of a port, based on the Egress List of the VLAN associated

with it. Each VLAN has an Egress List that specifies the ports out of which frames can be forwarded, and specifies

whether the frames will be transmitted as tagged or untagged frames.

Ingress rules are a means of filtering out undesired traffic on a port. When Ingress Filtering is enabled, a port

determines if a frame can be processed based on whether the port is on the Egress List of the VLAN associated with

the frame.

When an untagged packet arrives at the switch port, the switch will write a VLAN ID into the header of the frame

according to the PVID (port VLAN) port definition. Typically, most switches today have all ports are set to a default

PVID of 1. When a tagged frame arrives at a switch port the tag is respected.

A VID defines the member of a port group. A packet can only travel inside a member port when the member port is

part of a VID port group. Different VID groups aren’t visible to one another

VID: (Virtual LAN ID) It is an definite number of ID which number is from 1 to 4094.

PVID: (Port VID) It is an untagged member from 1 to 4094 of default VLAN.

Link Type: Access means the port can receive or send untagged packets.

Trunk means that the prot can receive or send tagged packets.

TCI (Tag Control Information field) including user priority, Canonical format indicator(CFI) and VLAN ID.

TPID(Tag Protocol Identifier) defined value of 8100 in hex. When a frame has the EtherType equal to 8100H, this frame

carries the tag IEEE 802.1Q / 802.1P.

Priority field defines user priority, giving eight (23 = 8) priority levels. IEEE 802.1P defines the operation for these 3

user priority bits.(Refer to following table)

CFI(Canonical Format Indicator) is always set to zero for Ethernet switches. CFI is used for compatibility reason

between Ethernet type network and Token Ring type network. If a frame received at an Ethernet port has a CFI set to

1, then that frame should not be forwarded as it is to an untagged port.

VID (VLAN ID) is the identification of the VLAN, which is basically used by the standard 802.1Q. It has 12 bits and allow

the identification of 4096 (212) VLANs. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and

value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

The VPN Router initially default configures one VLAN, VID=1.

A port such as LAN1 to 4, DSL or sniffing can have only one PVID, but can have as many VID as the VPN Router has

memory in its VLAN table to store them.

Ports in the same VLAN group share the same frame broadcast domin thus increase network

performance through reduced boardcast traffic. VLAN groups can be modified at any time by adding, moving or

changing ports without any re-cabling.

Before enabling VLANs for the VPN Router, you must first assign each port to the VLAN group(s) in which it will

participate. By default all ports are assigned to VLAN1 as untagged ports. Add a port as a tagged port if you want it to

carry traffic for one or more VLANs, and any intermediate network devices or the host at the other end of the

connection supports VLANs. Then assign ports on the other VLAN-aware network devices along the path that will carry

this traffic to the same VLAN(s), either manually or dynamically using GVRP. However, if you want a port on this VPN

Router to participate in one or more VLANs, but none of the intermediate network devices nor the host at the other

end of the connection supports VLANs, then you should add this port to the VLAN as an untagged port.

Note: VLAN-tagged frames can pass through VLAN-aware or VLAN-unaware network

Inter-connection devices, but the VLAN tags should be stripped off before passing it on to any end-node host that

does not support VLAN tagging.

VLAN Classification – When the VPN Router receives a frame, it classifies the frame in one of two ways. If the frame is

untagged, the VPN Router assigns the frame to an associated VLAN (based on the default VLAN ID of the receiving

port). But if the frame is tagged, the VPN Router uses the tagged VLAN ID to identify the port broadcast domain of the

frame.

Port Overlapping – Port overlapping can be used to allow access to commonly shared network resources among

different VLAN groups, such as file servers or printers.

Untagged VLANs – Untagged (or static) VLANs are typically used to reduce broadcast traffic and to increase security. A

group of network users assigned to a VLAN form a broadcast domain that is separate from other VLANs configured on

the VPN Router. Packets are forwarded only between ports that are designated for the same VLAN. Untagged VLANs

can be used to manually isolate user groups or subnets.

PVID - VLAN ID assigned to untagged frames received on the interface. (Default: 1)

If an interface is not a member of VLAN 1 and you assign its PVID to this VLAN, the interface will automatically be

added to VLAN 1 as an untagged member. For all other VLANs, an interface must first be configured as an untagged

member before you can assign its PVID to that group.

Link Type - Sets the port to accept the frame types: “Access” means the port can only receive or send untagged frame

types. “Trunk” means that the prot can only receive or send tagged frame types.

PPoorrtt--BBaasseedd VVLLAANN

Click Port-Based VLAN to configure the VPN Router.

Port-Based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its

associated port.

When using the port-based VLAN, the port is assigned to a specific VLAN independent of the user or system attached

to the port. This means all users attached to the port should be members in the same VLAN. The network

administrator typically performs the VLAN assignment. The port configuration is static and cannot be automatically

changed to another VLAN without manual reconfiguration.

As with other VLAN approaches, the packets forwarded using this method do not leak into other VLAN domains on the

network. After a port has been assigned to a VLAN, the port cannot send to or receive from devices in another VLAN.

For example,

The default setting is all ports connected which means all ports can communicate with each other. That is, there are

no virtual LANs. The option is the most flexible but the least secure.

A static route is one that is manually installed by your network administrator. This is a very efficient way to transfer

data from one subnet to another despite the fact that this type of route is manually intensive.

Static route is a path in the router that indicates how it will reach a certain subnet by taking a specific path.

The opposite of a static route is a dynamic route. Dynamic routes are created by routing protocols.

Static routes have advantages and disadvantages as compares to dynamic routes.

Advantages of Static Routes

Static routes are easier to configure

No need for overhead on the routing protocol

As long as you have a tight IP mask, this offers you reliable security

Disadvantages of Static Routes

In order to make changes in the network, you have to manually configure the route

When network outage is experienced, it does not automatically route around

Although this is quite easy to configure, it might not work for large and complicated networks

It is important that any network administrator have substantial knowledge about static routes. Although this type of

route may not be as effective with large networks, they are quite useful in any size of networks. Meanwhile, even if

you have setup a dynamic route, there are cases that still require a static route.

QQooSS

QoS(Quality of Service) refers to both a network’s ability to deliver data with minimum delay, and the networking

methods used to control the use of bandwidth. Without QoS, all traffic date is equally likely to be dropped when the

network is congested. This can cause a reduction in network performance and mark the network inadequate for

time-critical application such as video-on-demand.

QoS (Quality of Service) is to decide which PCs can get the priorities to pass though VPN Router once if the bandwidth

is exhausted or fully saturated.

VLAN Tag Priority uses the tag field information which has been inserted into an Ethernet frame. If a port has an

IIPP DDSSCCPP

Differentiated Services (DiffServ) is a class of service(CoS) model that enhances best-effort Internet services by

differentiating traffic by users, service requirements and other criteria. Packet are specifically marked, allowing

network nodes to provide different levels of service, as appropriate for video playback, voice calls or other

delay-sensitive applications, via priority queuing or bandwidth allocation.

DiffServ defines a new DS(Differentiated Services) field to replace the Type of Service(ToS) field in the IP header. The DS

field contains a 2-bits unused field and 6-bits DSCP field which can define up to 64 service levels.

The following figure illustrates the DS field:

The DSCP value used to identify 64 levels (26=64) of service determines the forwarding behavior that each packet gets

across the DiffServ network. Based on the marking rule different kinds of traffic can be marked for different priorities

of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.

The following is an illustration about how the bits are used in DSCP field.

The standardized DiffServ field of the packet is marked with a value so that the packet receives a particular forwarding

treatment at each network node.

RFC 2597 defines the assured forwarding (AF) classes. There are four AF classes, AF1x through AF4x. Within each class,

there are three drop probabilities. Depending on a given network's policy, packets can be selected for a PHB based on

required throughput, delay, jitter, loss, or according to priority of access to network services.

Classes 1 through 4 are referred to as AF classes.

The following table illustrates the DSCP coding for specifying the AF class with the probability. Bits 0, 1, and 2 define

the class; bits 3 and 4 specify the drop probability; bit 5 is always 0.

Traffic policing can propagates bursts. When the traffic rate reaches the configured maximum rate, excess traffic is

dropped (or remarked). The result is an output rate that appears as a saw-tooth with crests and troughs. In contrast to

policing, traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over

increments of time. The result of traffic shaping is a smoothed packet output rate.

RRIIPP

The RIP (Routing Information Protocol) is a dynamic routing protocol used in local and wide area networks. It’s a very

simple protocol, based on distance-vector routing algorithms.

As such it is classified as an IGP (interior gateway protocol). VPN Router is support version 1 (RFC1058) and Version 2

(RFC2453).

It can set the specified interface (LAN, WAN1 to WAN8) to

passive mode. On passive mode interface, all receiving

packets are processed as normal and rip does not send either multicast or unicast RIP packets.

VViirrttuuaall SSeerrvveerr

This feature allows you to make servers on your LAN accessible to Internet users. Normally, Internet users would not

be able to access a server on your LAN because:-

(1) Your server does not have a valid external IP address.

(2) Attempts to connect to devices on your LAN are blocked by the firewall in this device IP address seen by Internet

Users

To interface users, all virtual servers on your LAN have the same IP address. The IP address is allocated by your ISP.

This address should be static, rather than dynamic, to make it easier for Interface users to connect to your Servers.

Once configured, anyone on the Internet can connect your virtual servers. They must use the Internet IP address .The

IP address allocated to you by your ISP.

It is more convenient if you are using fixed IP address from your ISP, rather than dynamic.

However, you can use the dynamic DNS feature to allow users to connect to your V irtual servers using a URL, rather

than an IP address.

TCP (Transmission Control Protocol) is a connection-oriented protocol that is responsible for reliable communication

between two end processes. The unit of data transferred is called a stream, which is simply a sequence of bytes.

UDP (User Datagram Protocol) offers only a minimal transport service (non-guaranteed datagram delivery) and gives

applications direct access to the datagram service of the IP layer. UDP is used by applications that do not require the

level of service of TCP or that wish to use communications services (e.g., multicast or broadcast delivery) not available

from TCP.

DDMMZZ

In computer security, DMZ (demilitarized zone) is a physical or logical sub-network that contains and exposes an

organization's external services to a larger untrusted network, usually the Internet. The term is normally referred to as

a DMZ by IT professionals. It is sometimes referred to as a Perimeter Network. The purpose of a DMZ is to add an

additional layer of security to an organization's LAN (Local Area Network); an external attacker only has access to

equipment in the DMZ, rather than any other part of the network.

If enabled this feature, allows one or more computers on your LAN to be exposed to all users on the internet. You can

set a DMZ PC for each WAN IP address. If you only have 1 WAN IP address, only 1 DMZ PC can be used.

33..11..66..

DDDDNNSS

DDNS (Dynamic DNS Free) allows you to create a hostname that points to your home or office IP address, providing an

easy-to-remember URL for quick access.

You must register for the service at one of the listed service providers. You can reach the service provider’s Web Site by

selecting them in the list. Apply for a domain name, and ensure it is allocated to you.

Details of your DDNS account (Host name, Name, password) must then be entered and saved on this screen.

The device will then automatically ensure that you current IP address is recorded by the DDNS service provider from

the internet, users will now be able to connect to your Virtual Servers using your Domain name.

33..55..1100.. IIGGMMPP

IGMP (Internet Group Management Protocol) proxy can be used to implement multicast routing. It works by IGMP

frame forwarding. VPN Router’s IGMP proxy supports IGMP version 2 (RFC2236).

IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the system discovered through

standard IGMP interfaces. The system acts as a proxy for its hosts.

IGMP snooping is the process of listening to IGMP network traffic. IGMP snooping, as implied by the name, is a feature

that allows VPN Router to "listen in" on the IGMP conversation between hosts to this VPN Router by processing the

IGMP packets sent in a multicast network.

When IGMP snooping is enabled, VPN router will analyzes all IGMP packets between hosts connected to the VPN

router and multicast routers in the network. When the VPN router hears an IGMP report from remote side for a given

multicast group, the VPN router adds the host's port number to the multicast list for that group. And, when the VPN

Router hears an IGMP leave, it removes the host's port from the table entry.

A firewall is a set of related programs that protects the resources of a private network from other networks. It is

helpful to users that allow preventing hackers to access its own private data resource accidentally.

There have three security levels for setting: Basic firewall security, Automatic firewall security and advanced firewall

security.

X’mas tree scan: It can send a TCP frame to a remote device with the URG, PUSH, and FIN flags set. This is called a

Xmas tree scan because of the alternating bits turned on and off in the flags byte, much like the lights of a Christmas

tree.

Null scan: The null scan turns off all flags, creating a lack of TCP flags that should never occur in the real world.

SYN flood: A SYN flood is a form of denial-of-service attack, attempts to slow your network by requesting new

connections but not completing the process to open the connection. Once the buffer for these pending connections is

full a server will not accept any more connections and will be unresponsive.

ICMP flood: A sender transmits a volume of ICMP request packets to cause all CPU resources to be consumed serving

the phony requests.

UDP Flood: A UDP flood attack is a denial-of-service (DoS) attack using the User Datagram Protocol(UDP). A sender

transmits a volume of requests for UDP diagnostic services which cause all CPU resources to be consumed serving the

phony requests.

Ping of Death: A ping of death (POD) attack attempts to crash your system by sending a fragmented packet, when

reconstructed is larger than the maximum allowable size.

Land attack: A land attack is an attempt to slow your network down by sending a packet with identical source and

destination addresses originating from your network.

IP Spoofing: IP Spoofing is a method of masking the identity of an intrusion by making it appeared that the traffic came

from a different computer. This is used by intruders to keep their anonymity and can be used in a Denial of Service

attack.

Smurf attack: The Smurf attack is a way of generating a lot of computer network traffic to a victim host. That is a type

of denial-of-service attack. A Smurf attack involves two systems. The attacker sends a packet containing a ICMP echo

request (ping) to the network address of one system. This system is known as the amplifier. The return address of the

ping has been faked (spoofed) to appear to come from a machine on another network (the victim). The victim is then

flooded with responses to the ping. As many responses are generated for only one attack, the attacker is able use

many amplifiers on the same victim.

Fraggle attack: A Fraggle attack is a type of denial-of-service attack where an attacker sends a large amount of UDP

echo traffic to IP broadcast addresses, all of it having a fake source address. This is a simple rewrite of the smurf attack

code.

VVPPNN

A VPN (Virtual Private Network) provides a secure connection between 2 points, over an insecure network. The Secure

is called a VPN Tunnel.

The VPN Router supports three main type of VPN: IPsec, L2TP and PPTP.

IIPPsseecc

IPsec is a near-ubiquitous VPN security standard, designed for use with TCP/IP networks. It works at the packet level,

and authenticates and encrypts all packets traveling over the VPN Tunnel. Thus, it does not matter what applications

are used on your PC. Any application can use the VPN like any other network connection.

IPsec VPNs exchange information through logical connections called SAs(Security Associations). An SA is simply a

definition of the protocols, algorithms and keys used between the two VPN devices(endpoints)

There are two security modes possible with IPsec:

Transport Mode – the payload (data) part of the packet is encapsulated through encryption but the IP header remains

in the clear (unchanged)

Tunnel Mode – everything is encapsulated including the original IP header, and a new IP header is generated. Only the

new header in the clear (i.e. not protected). This system provides enhanced security.

IKE(Interface Key Exchange) is an optional, but widely used, component of IPsec.

IKE provides a method of negotiating and generating the keys and IDs required by IPsec. If using IKE, only a single key is

required to be provided during configuration. Also, IKE supports using Certificates to authenticate the identify of the

remote user or gateway.

If IKE is not used, then all keys and IDs(SPIs) must be entered manually, and Certificates can’t be used, This is called a

“Manual Key Exchange”.

Enable

This indicates whether or not the policy is currently enabled. Use the Enable/Disable to toggle the state the selected

policy.

Policy name

The name of the policy. When creating a policy, you should select a suitable name.

Both office LAN networks must in different subnet with LAN to LAN application.

Functions of Pre-shared Key, VPN Connection, type and Security Algorithm must be identically set up on both sides.

Example: Configuring a IPSec Host-to-LAN VPN Connection

LL22TTPP

L2TP (Layer 2 Tunneling Protocol) is a tunneling protocol used to support VPNs. It doesn’t provide any encryption or

confidentiality by itself; it relies on an encryption protocol that it passes within the tunnel to provide privacy.

L2TP allows a PPP session to travel over multiple links and networks. PPP is used to encapsulate IP packets from the

user's PC or mobile device to the ISP, and L2TP extends that session across the Internet.

Example: Configuring L2TP LAN-to-LAN VPN Connection

The branch office establishes a L2TP VPN tunnel with head office to connect two private networks over the Internet.

The routers are installed in the head office and branch office accordingly.

Both office LAN networks must in different subnet with LAN to LAN application.

Functions of Pre-shared Key, VPN Connection Type and Security Algorithm must be identically set up on both sides.

PPPPTTPP

PPTP( Point-to-Point Tunneling Protocol)is a private network of computers that uses the public Internet to connect

some nodes. Because the Internet is essentially an open network, the PPTP is used to ensure that messages

transmitted from one VPN node to another are secure. With PPTP, users can dial in to their corporate network via the

Internet.

There are two types of PPTP VPN supported; Remote Access and LAN-to-LAN.

Example: Configuring a Remote Access PPTP VPN Dial-out Connection

A company’s office establishes a PPTP VPN connection with a file server located at a separate location. The router is

installed in the office, connected to a couple of PCs and Servers.

Example: Configuring a PPTP LAN-to-LAN VPN Connection

The branch office establishes a PPTP VPN tunnel with head office to connect two private networks over the Internet.

The routers are installed in the head office and branch office accordingly.

Both office LAN networks MUST in different subnet with LAN to LAN application.

Configuring PPTP VPN in the Head Office

The IP address 192.168.1.254 will be assigned to the router located in the branch office. Please make sure this IP is not

used in the head office LAN.

Configuring PPTP VPN in the Branch Office

The IP address 69.1.121.33 is the Public IP address of the router located in head office. If you registered the DDNS

(please refer to the DDNS section of this manual), you can also use the domain name instead of the IP address to

reach the router.

VPN Configuration

VPN Endpoint address

Each VPN endpoint must be configured to initiate or accept connections to the remote VPN client gateway. Usually,

this requires having a fixed Internet IP address. However, it possible for a VPN gateway to accept incoming connections

from a possible for remote client where the client’s IP address is not known in advance.

If connecting 2 LANs, this requires that:

Each endpoint must be aware of the IP address used on the other endpoint.

The 2 LANs must use different IP address ranges.

VPN Pass-through

Here, a PC on the LAN behind the VPN router is using VPN software, but the VPN router is not acting as CPN endpoint,

It is only allowing the VPN connection.

The PC software can use any VPN protocol supported by the remote VPN.

The remote VPN server must support client PCs which are behind a NAT router, and so have an IP address which is not

valid on the Internet.

The VPN router requires no VPN configuration, since it is not acting as a VPN endpoint.

Client PC to VPN Gateway

Here, the PC must run appropriate VPN client software in order to connect, via the Internet to VPN router. Once

connected, the client PC has same access to LAN resources as PCs on the local LAN.

Connecting 2 VPN gateways

This allows two LANs to be connected PCs on each endpoint gain secure access to the remote LAN.

The 2 LANs must use different IP address ranges.

The VPN policies at each end determine when a VPN tunnel will be established, and what system on the remote LAN

can be accessed once the VPN connection is established.

It is possible to have simultaneous VPN connections to many remote sites.

Remote VPN Endpoint

MMAACC ffiilltteerr

In computer networking, MAC Filtering refers to a security access control methodology whereby the 48-bit

address(XX:XX:XX:XX:XX:XX) assigned to each network device is used to determine access to the network.

MAC addresses are uniquely assigned to each network device, so using MAC filtering on a network permits and denies

network access to specific devices through the use of black lists and white lists. While the restriction of network

access through the use of lists is straightforward, an individual person is not identified by a MAC address, rather a

device only, so an authorized person will need to have a white list entry for each device that he would use to access

the network.

While giving a wireless network some additional protection, MAC Filtering can be circumvented by scanning a valid

MAC and then changing the own MAC into a validated one.

SSNNTTPP

Time synchronization is an essential element for any business, which relies on the IT system. The reason for this is that

these systems all have clock that is the source of timer for their filing or operations. W ithout time synchronization,

these system’s clocks vary and cause the failure of firewall packet filtering schedule processes, compromised security,

or virtual server working in wrong schedule.

SNTP is the acronym for Simple Network T ime Protocol, which is an adaptation of the Network Time Protocol (NTP)

used to synchronize computer clocks in the Internet. SNTP can be used when the ultimate performance of the full NTP

implementation. The function only supported on router mode.

There are two methods to synchronize time, synchronize with PC or SNTP. If you choose synchronize with PC, the VPN

Router will synchronize with PC’s internal timer. If you choose SNTP, the VPN Router will use the protocol to

synchronize with the time server. For synchronization the time server with SNTP, needs to configure service,

time_server and time_zone. For synchronization with PC, doesn’t need to configure the above parameters.

SSNNMMPP

Simple Network Management Protocol (SNMP) provides for the exchange of messages between a network

management client and a network management agent for remote management of network nodes. These messages

contain requests to get and set variables that exist in network nodes in order to obtain statistics, set configuration

parameters, and monitor network events. SNMP communications can occur over the LAN or WAN connection.

The router can generate SNMP traps to indicate alarm conditions, and it relies on SNMP community strings to

implement SNMP security.

This router support both MIB I and MIB II.

TTRR--00669

TR-069 (short for Technical Report 069) is a DSL Forum technical specification entitled CPE WAN Management

Protocol (CWMP). It defines an application layer protocol for remote management of end-user devices.

As a bidirectional HTTP based protocol it provides the communication between CPE (customer premises equipment)

and ACS (Auto Configuration Servers). It includes both a safe auto configuration and the control of other CPE

management functions within an integrated framework. Using TR-069 the terminals can get in contact with the ACS

(Auto Configuration Servers) and establish the configuration automatically.

ACS URL

URL for the CPE to connect to the ACS using the CPE WAN Management Protocol. This parameter MUST be in the form

of a valid HTTP or HTTPs URL. An HTTPs URL indicates that the ACS supports SSL. The “host” portion of this URL is used

by the CPE for validating the certificate from the ACS when using certificate-based authentication.

ACS User Name

Username used to authenticate the CPE when making a connection to the ACS using the CPE WAN Management

Protocol. This username is used only for HTTP-based authentication of the CPE.

ACS Password

Password used to authenticate the CPE when making a connection to the ACS using the CPE WAN Management

Protocol. This password is used only for HTTP-based authentication of the CPE.

SSH (or Secure Shell) is a protocol that can be used to log into a remote machine (your Virtual Server) and provide

secure encrypted communications between your VON Router and your local computer. All of the commands you would

use in a Telnet client, you can use in an SSH client. The only difference is that the communication is made via encrypted

channels to and from your VPN Router.

Once you have chosen a SSH (or Telnet) client, connecting to your Virtual Server is extremely simple. Although SSH

(and Telnet) clients vary in their exact configuration, most of them will simply require you to specify a "remote host".

Your remote host is your VPN Router, so you would specify your domain name (or your temporary domain, if

applicable) or IP address.

Once you are connected, you will be prompted for your login name and login password. You specified both your login

name and login password when you ordered your VPN Router. After the login process is successful, you will have

gained access to your VPN Router and can now issue commands at the command prompt.

For SSH, you may change the default service port by typing the new port number. If you change the default port

term for delay) between the two device. You can use a ping test to troubleshoot connectivity problems with your

home network. Ping tests are also commonly used to measure the delay ("lag") with some Internet servers.

To execute a ping test, you simply identify the Web site or other remote server / computer by its IP address. The result

of a ping test includes confirmation that connection was successful, along with a series of numbers that represent the

communication delay in milliseconds (ms).

Ping reports the percentage of packets acknowledged by the remote host. Typically this number will be 100% (as in the

example above) or 0%. When an Internet host pings at 0%, this does not necessarily mean the server is "down" or

unavailable. Internet Web servers especially may be configured to disregard ping requests for security purposes.

The results of a ping test vary depending on the quality of the Internet / network connection. A good broadband

Internet connection typically results in ping test latency of less than 100 ms, often less than 30ms. A satellite Internet

connection normally suffers from latency above 500ms.

On intranets and other private LANs, ping can be an especially useful network diagnostic tool. One scenario that will

result in a ping response rate of other than 0% or 100% occurs when a host is shutdown and leaves the network (or

boots and joins the network).

It is also possible for ping packets to be lost in transit, causing ping to report a host as unavailable when in fact it is

available but unreachable. One cause of lost or dropped packets is extreme levels of traffic. In general, ping utilities will

be unusable on heavily-loaded networks.

IP Address : Which IP address you want to ping

Size : Size of byte packets to the destination, default is 56

Count : Ping count number, default is 3

Update : Updated time, default is 2

The trace route command traces the network path of Internet routers that packets take as they are forwarded from

your VPN router to a destination address. The "length" of the network connection is indicated by the number of

Internet routers in the trace route path.

Trace routes can be useful to diagnose slow network connections. For example, if you can usually reach an Internet

site but it is slow today, then a trace route to that site should show you one or more hops with either long times or

marked with "*" indicating the time was really long. If so, the blockage could be anywhere from your Internet service

provider to a backbone provider, and there is likely little you can do except wait with the infinite patience of the

mighty oak.

Host name or IP: Type which Host name and IP address you want to ping.

Update Interval: Set the amount of seconds to wait for an answer from each host before giving up, default of 2

Abbrev. Full Term Meaning

EoA Ethernet-over-ATM EoA protocol is commonly used to carry data

between local area networks that use the Ethernet

protocol and wide-area networks that use the ATM

protocol. Many telecommunications industry

networks use the ATM protocol. ISPs who provide

DSL services often use the EoA protocol for data

transfer with their customers' DSL modems.

VCI Virtual Channel Identifier for set up ATM Permanent Virtual Channels(PVC).

EoA

EoA (Ethernet-over-ATM) protocol is commonly used to carry data between local area networks that use the Ethernet

protocol and wide-area networks that use the ATM protocol. Many telecommunications industry networks use the

ATM protocol. ISPs who provide DSL services often use the EoA protocol for data transfer with their customers' DSL

modems.

EoA can be implemented to provide a bridged connection between a DSL modem and the ISP. In a bridged connection,

data is shared between the ISP's network and their customer's as if the networks were on the same physical LAN.

Bridged connections do not use the IP protocol. EoA can also be configured to provide a routed connection with the

ISP, which uses the IP protocol to exchange data.

IPoA

IPoA (Dynamic IP over ATM) interfaces carries IP packets over AAL5. AAL5 provides the IP hosts

on the same network with the data link layer for communications. In addition, to allow these

hosts to communicate on the same ATM networks, IP packets must be tuned somewhat. AS the

bearer network of IP services, ATM provides high speed point-to-point connections which

considerably improve the bandwidth performance of IP network. On the other hand, ATM

provides excellent network performance and perfect QoS.

PPPoA / PPPoE

PPPoA (point-to-point protocol over ATM) and PPPoE (point-to-point protocol over Ethernet) are authentication and

connection protocols used by many service providers for broadband Internet access. These are specifications for

connecting multiple computer users on an Ethernet local area network to a remote site through common customer

premises equipment, which is the telephone company's term for a modem and similar devices. PPPoE and PPPoA can

be used to office or building. Users share a common Digital Subscriber Line (DSL), cable modem, or wireless

connection to the Internet. PPPoE and PPPoA combine the Point-to-Point Protocol (PPP), commonly used in dialup

connections, with the Ethernet protocol or ATM protocol, which supports multiple users in a local area network. The

PPP protocol information is encapsulated within an Ethernet frame or ATM frame.
