Subscription for ADSL Service

To use the ADSL Router, you have to subscribe for ADSL service from your broadband service provider. According to the service type you subscribe, you will get various IP addresses:

Dynamic IP: If you apply for dial-up connection, you will be given an Internet account with username and password. You will get a dynamic IP by dialing up to your ISP, such as under PPPoA, PPPoE, or MER mode.

Static IP address: If you apply for full-time connectivity, you may get either one static IP address or a range of IP addresses from your ISP. The IP address varies according to different ADSL service provider, such as using IPoA or MER mode.

Local Network – IGMP Sn ooping

Traditionally, IP packet s are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 se nder to everyone on the network). Multicast delivers

IP packets to just a group of hosts on th e network.

Without IGMP snooping, multicast traff ic is treated in the same manner as broadcast traffic, that is, it is forwarded to all ports . With IGMP snooping, multicast traffic of a group is only forwarded to ports th at have members of that group. IGMP snooping generates no additional network traffic , allowing you to significantly reduce multicast traffic passing through your switch.

The figur e below shows a simple network connected via the ADSL router. There are four Ethernet clients and one USB client on the LAN interface.

Now suppose the video server is the multicast transmitter and host A and D are multicast receivers. If we do not turn on the IGMP snooping function, the router will

83

ADSL Router User Manual forward the multicast traffic to all hosts connecting to this router and consequently block and interrupt the traffic of the othe r users who do not want to receive the multicast service, shown as the followin g figure.

When IGMP snooping is invoked, it m akes the system aware to establish the best path for multicast service to save LAN b andwidth. Refer the figure below, just as desired, only host A and D will actually r eceive multicast traffic when IGMP snooping is enabled.

84

While IGMP snooping is enabled, the IGMP packets will be monitored, the membership information will be recorded and processed, and the multicast traffic will only be forwarded to those LAN interfaces, such as Ethernet and USB, which are bonded to the subscribed multicast groups. Thus it helps to sav e the bandwidth and helps the devices to perform more effectively.

Check Enable IGMP Snooping and click Apply to invoke this function.

When IGMP Snooping is enabled, you can check the box below to filter out multicast packets which will be sent to your local network if no user plays multimedia movies.

Note that the IGMP proxy must be enabled first. If the IGMP Snooping function is not available as shown in the following figure, you have to enable the IGMP Proxy first.

If the PVC you’re using is NAT enabled, remember to turn on the

IGMP Proxy at the same time. Please refer to Internet – IGMP Proxy for more information.

If you choose PPPoE or Bridging, you will see the option for 802.1Q

VLAN Tagging.

802.1Q VLAN Tagging:

802.1Q-compliant switch ports can be configured to transmit tagged or untagged frames. A tag field containing VLAN (and/or 802.1p priority) information can be inserted into an Ethernet frame. If a port has an

802.1Q-compliant device attach ed

(such as a nother switch), these tagged frames can carry VLAN membership information between switches, thus letting a VLAN span multiple switches. However, it is important for network administrators to ensure ports with non-802.1Q-compliant de vices attached are configured to transmit untagged frames. Many NICs for PCs and printers are not 802.1Q-compliant.

If they receive a tagged frame, the y will not understand the VLAN tag and will drop the frame. Also, the maximum legal Ethernet frame si ze for tagged frames was increased in

802.1Q (and its companion, 802.3a

c) from 1,518 to 1 ,522 bytes.

After checking Enable 802.1Q VLAN

Tagging, you will have to enter a

VLAN ID, as shown in the fig ure.

VLAN ID:

The VLAN Id entifier is a 12 bit field. It uniquely identifies the VLAN to which the frame belongs to and can have a value between 0 and 4095.

Click Next to continue.

Notice that 802.1Q VLAN

Tagging function can only be invoked under PPPoE and

Bridging Mode; the system will not provide this option while setting PPPoA or IPoA mode.

Virtual Server – Port Forwarding

The Router implements NAT to make your entire local network appear as a single machine to the Internet. The typical situation is that you have local servers for different services and you want to make them publicly accessible. With NAT applied, it will translate the internal IP addresses of these servers to a single IP address that is unique on the Internet. NAT function not only eliminates the need for multiple public IP addresses but also provides a measure of security for your LAN.

When the router receives an incoming IP packet requesting for accessing your local server, the router will recognize the service type according to the port number in this packet (e.g., port 80 indicates HTTP service and port 21 indicates FTP service). By specifying the port number, the router knows which service should be forwarded to the local IP address that you specified.

After setting the virtual server, you should modify the filter rule about the port and service information which you set on the virtual server. Because the firewall protects the router by filter rule, you should update the filter rule after you set up the virtual server.

Virtual Server function 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:

Your server does not have a va lid external IP Address.

Attempts to connect to devices on your LAN a re blocked by the firewall in this device.

The Virtual Server feature solves these problems and allows Internet users to connect to your servers, as illustrated be low:

92

IP Address seen by Internet Users

Once configured, anyone on the Intern et can connect to your Virtual Servers.

Please note that, in the above picture, both Internet users are connecting to the same IP address, but using different protocols, such as Http://203.70.212.52 and

F tp://203.70.212.52.

T o Internet users, all virtual servers on your LAN have the same IP Address. This IP

Address is allocated by your ISP. This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use Dynamic DNS feature to allow users to connect to your virtual servers by using a URL, instead of an IP address.


IP addresses can be automatically redirected to local servers configured with private

IP addresses. In other words, depending on the requested service (TCP/UDP port number), the router redirects the external service request to the appropriate server

(located at another internal IP address).

Add New Port Forwarding

To set a virtual server, please open the

Virtual Server item from the

Advanced setup menu.

To add a new Port Forwarding, please click Add from the Port Forwarding web page.

Pre-defined:

Choose one of the service types from the first drop-down list, such as

NAT ALG Configuration

The need for IP address translation arises when a network's internal IP addresse s can no t be used outside the network either for security reasons or because they are invalid for use outside the network. Use of NAT (Network Address Transla tion) devices allows local hosts on such private networks to transparen tly access th e external global Internet and enables access to selective local hosts fro m the outside.

ALG (Application Level Gateway) is a security component that augments a firewall or

NAT employed in a computer network. A LG allows legitimate application data to pass through the security checks of the firewall that would have otherwise restricted t he traffic for not meeting its filter criteria. ALG application specific translation agents allow an application on a host in one address realm to connect to its counterpart running on a host in different realm transparently. An ALG may int eract with NAT to set up state, use NAT sta te information, modify application specific payload and perform whatever else is necessary to get the application running across disparate address realms.

Enable VPN ALG:

VPN ALG allows two or more simultaneous VPN connection s through this router. Check the box to invoke this function.

Enable SIP ALG:

SIP ALG allows two or more simultaneous VoIP phone calls made by VoIP clients through this router. The default setting for SIP ALG is enabl ed.

Transparent use of SIP-based devices in a

NAT scenario requires that modifications be made to the SIP messages. These modifications are performed by the ALG.

A SIP ALG provides functionality to allow

VoIP traffic to pass both from the private to public and public to private side of the firewall when using Network Address

Translation (NAT). The SIP-ALG inspects and modifies SIP traffic to allow SIP traffic to pass through the firewall so that person-to-person SIP sessions may be established.

Firewall

The firewall is a kind of software that interrupts the data between the Internet and your computer. It is the TCP/IP equivalent of a security gate at the entrance to your company. All data must pass through it, and the firewall (functions as a security guard) will allo w only authorized data to be passed into the LAN.

What the firewall can do? It can:

deny or permit any packet from pa ssing through explicitly

distinguish between various interfa ces and match on the following fields:

source and destination IP add ress

port

To keep track of the performan ce of IP Filter, a logging device is used. The device supports logging of the TCP/UDP and IP packet headers and the first 129 bytes of the packet (including headers) whene ver a packet is successfully passed through or

blocked, and w henever a packet matches a rule being setup for suspicious packets.

An example for firewall setup:

This picture shows the most common and easiest way to employ the firewall.

Basically, you can install a packet-filtering router at the Internet gateway and then configures the filter rule in the router to block or filter protocols and addresses. The systems behind the router usually have a direct access to the Internet; however some dangerous services such as NIS and NFS are usually blocked.

For the security of your router, set the firewall is an important issue.

Firewall – Bridge Filterin g

The bridge filtering mechanism p rovides a way for the users to define rules to allow/deny packets through the bridge based on source MAC address and/or destination MAC addre ss. When bridge filtering is enabled, each packet is examined against the each defi ned filter rules sequentially, and when a matched is determined, the packets will be blocked.

This page allows you to define the brid ge packet filtering rules to block those redundant packets with specific protoco ls and MAC addresses.

Choose Disabled to disable the bridge filtering function. Click Enabled to monitor and block redundant packets.

To initiate the Bridge Filtering rules, select the Enabled radio button an d click Apply.

Click Add to configure a new bridge filtering rule.

Note that the Add option is available only when there i s a bridge mode PVC on this device.

Select traffic dir ection from the drop down menu, an d check the network interface which you want this rule to apply on. Then, choose a protocol and define the source or destination MAC address which you want to control.

There h directio n: Outbound means from local network to Internet; Inbound means from Internet to local network;

Bi-direction includes both directions.

The protocols that you can choose is listed as the right figure shows.

Select one proper protocol for this brid ge filtering rule.

For example, if we choose Outbound, check br_0_35, select PPPoE as protocol, and enter 00:90:96:01:2A:C3 into the Source MAC Address field, then after clicking Apply, we will see the result as shown in the right.

You can use Add or Delete button to maintain the bridge filtering rules.

Firewall – IP Filtering

This page allows you to specify the IP packet filtering rules to prevent the services accessed from the Internet hosts or limit the Internet access fo r local hosts.

Choose Disabled to disable the firewall function. Click Enabled to invoke the settings that you set in this web page.

To initiate the IP Filtering, please select the Enabled radio button and click Apply. The web page will be shown as the right picture.

Select the direction to filter packets:

Inbound means the data is transferred from outside onto your computer.

Outbound means the data is transferred from your computer onto outside through Internet. Please choose Outbound traffic or Inbound

traffic as the direction for filtering packets.

Then, to add a new IP Filtering rule, click Add.

98

This page provides some settings for you to adjust for adding a new outbound IP Filtering.

Allow Traffic:

Choose No to stop the data transmission, Yes to permit the data pass through.

Protocol:

Here provides several default policies for security levels for you to choose. If you don’t want to use the predefined setting, you can use User Defined to set a customized protocol according to the necessity.

When you choose User Defined setting, you have to enter a port number in the “as” field.

Source/Destination IP address:

To specify IP address to allow or deny data transmission, please pull down the drop-down menu to choose a proper one.

The setting All means that all the IP addressed in the network are allowed or denied to pass through in Internet.

If you choose Single or Sub net, you will have to key in the specific IP address (and Netmask for subnet) as the start/end point to let the router identify for granting or denying passing through.

Port Range:

The port range is from 0 to 65535.

Please key in the start point and end point for the IP Filtering.

After finish the settings, click Appl y.

Quality of Service

QoS (Quality of Service) is an industr y-wide initiative to provide preferential treatment to certain subsets of data, e nabling that data to traverse the Internet or intranet with higher quality transmiss ion service.

There have been two generations of q uality of service architectures in the Internet.

The interpretation of the Type of Service Octet in the Internet Protocol header varies between these two generations.

The First generation: Precedence and type of service bits

The refined definition of the initial Type of Service Octet looks like this:

2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0

Precedence Type of Service Field

The Second generation: Differentiate d services code point

The Diff erentiated Service Code Point is a selector for router's per-hop behaviors

(PHB). As a selector, there is no implication that a numerically greater DSCP implies a better network service. RFC2474 redefined the Type of Service Octet to be:

2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0

Differentiated Services Code Point ECT CE

The fields ECT and CE are nothing to do with quality of service. They are spare bits in the IP header used by Explicit Congestion Notification. As can be seen, the DSCP totally overlaps the old Precedence field. So if values of DSCP are carefully chosen then backward compatibility can be achieved. This leads to the notions of "class", each class being the group of DSCP with the same Precedence value. Values within a class would offer similar network services but with slight differences. Classes were initially defined as:

DSCP Precedence

0 0

8 1

16 2

24 3

32 4

40 5

48 6

56 7

Pur pose

Express forwarding

Control

Control

Now, DSCP is what we are using for the QoS configuration on this device.

Among the classes you will see on the webpage, the BE (Best Effort) class possesses no guaranteed rates; the CS (Class Selector) values enable backward compatibility with the older IP-Precedence scheme ranges 0~7; the EF (Expedited

Forwarding) class is a low-loss, low-latency, low-jitter, assured-bandwidth, end-to-end service; AF (Assured Forwarding) provides for the delivery of IP packets in four independently forwarded AF classes, AF1x through AF4x. Within each AF class, an IP packet can be assigned one of three different levels of drop precedence.

This class is used when a service (application) requires a high probability of packets being forwarded, so long as the aggregate traffic from each site does not exceed the subscribed information rate (profile). Each of the four AF classes allocates a certain amount of forwarding resources, such as buffer space and bandwidth in each network node. When congestion occurs, the drop precedence of a packet determines the relative importance of the packet within the AF class.

You can start to configure the Bridge QoS/IP QoS rules on the Quality of Service webpage for your router.

101


Quality of Service – Bridge QoS

To classify the upstream traffic by assigning the transmission priority for different users’ data, please use

Bridge QoS to prioritize the data transmission.

The Bridge QoS allows you to set the settings based on layer two bridge packets.

Traffic Class Name:

Key in a name as the traffi c cla ss f or identification .

802.1p Priority:

Each incoming packet will be mapped to a specific priority level, so that these levels may be acted on individually to deliver traffic differentiation. Please choo se the number (from 0 t o 7, l ow t o hig h priority) for the 802.1p Priority.

Traffic Priority:

There are three options – Low,

Medium, and High that you can choose. The router will arrange the precedence for the traffic according to the traffic priority setting here.

As for the settings for the DSCP value and the WAN 802.1p value of the upstream packets, the y will be see n on the WAN side.

DiffServ Class (DSCP):

DiffServ is a com puter n etworking architecture that s pec ifies a simple , scalable and coar se-graine d mechanism for classifying, managi ng network traffic and providi ng QoS

(quality of service) guarantees on modern IP networks. DiffServ can, for example, be used to provide low-latency, guaranteed service to critical network traffic such as voice or video while providing simple best-effort traffic guarantees to non-critical services such as web traffic or file transfers.

The higher position the item appears, the smaller DSCP value it is (i.e., BE is the lowest while CS7 is the highest).

The corresponding DSCP value in the

IP header of the upstream packets will be overwritten by the selected value.

The default setting is No chang e.

102

WAN 802.1p:

If 802.1p is enabled on Internet connection, WAN 802.1p value of the upstream packets can be overwritten by the selected value. You may se lect a priority from the drop-down menu.

If you set the LAN 802.1p Priority 0 as the traffic condition, choose Low

traffic priority for this rule, set DSCP as BE, and WAN 802.1p as no

change, after clicking A pply, you will get the result as the figure in the right column.

Thus when the use rs’ data matches the traffic condition, the transmission will get a low traffic priority.

You may check the Delete box and press Delete to discard it, or click Add to create more.

Quality of Serv ice – IP QoS

To classify the upstream traffic by assigning the transmission priority o f the data for different users, please use

IP QoS to prioritize the data transmission.

The IP QoS allows you to set the settings based on layer three IP packets.

To add a new IP QoS settin g, press

Add in the page of Quality of

Service – IP QoS, a page same as the right side will appear.

Traffic Class Name:

Type a name as the traffic class for identification.

LAN Ports which traffic come from:

The IP QoS rules will be applied on the LAN ports you checked here. The default setting includes all ports.

Source MAC Address& MAC M ask/

Destination MAC Address& MAC

Mask:

Key in the sp ecific MAC Address or

MAC Mask of the devices which you want the QoS rule to be applied to, or simply leave it blank to include all.

Protocol:

Choose a proper interface for this function. If you don’t know how to select, simply use the default one.


103


Source IP/ Sub net Mask/ Port:

Key in the source IP address (e x.:

192.168.1.0) and subnet mask (ex.:

255.255.255.0) for the application (ex.

:

FTP, HTTP, and so on) that you want to invoke the QoS traffic rule. You ma y simply enter the source port, ranging from 0 to 65535, as the traffic condition.

Destination IP/ Subnet Mask/ P ort:

Enter the destination IP address

(ex.: 168.95.1.88) and subnet mask

(ex.:255. 255.255.0) for the application that you want to invoke the QoS traffi c rule. Or simply enter the destination

port for the traffic condition; it ranges from 1 to 65535.

Traffic Priority/ DiffServ Class

(DSCP)/ WAN 802.1p:

Please refer to the Bridge QoS section.

After finishing the settings, click

Apply, the new QoS setting will be shown as the example.

According to the example, we set four rules for IP QoS. In traffic A, w e set the destinatio n port as 1-1024, and the traffic priority is low; in traffic B , the

source port is from 201 to 8000, a nd the priority is medium; in traffic C , when the s ource IP is 192.168.1.0, subnet mask is 255.255.255.0, the traffic priority is high; in traffic D , when the traffic is heading to 168.95.1.88, the priority is high.

To delete the rules you set, simply click the check button below Delete item and click Delete button.

According to our example, the IP QoS configuration can be illustrated by the following figure in the next page.

While there are many PCs getting online, the PCs using port 201-8000 to access the internet will have

medium traffic priority, the

PCs carrying 192.168.1.x/

255.255.255.0 as IP address will have high traffic priority. In addition,

PCs heading to port 1-1024 will have a low priority, while the PCs accessing

168.95.1.88 will have a high priority.

104

Port Mapping

This page allows you to configure various port mapping groups which contains specific Internet connections and LAN ports. The user data will be only transmitted and received among the interfaces in the group.

Normally, this function only needed when more than two PVCs are available, for example, if we have two

PVCs, one uses PPPoE and the other uses Bridge mode, we may want to group certain connection to a specific port, especially when some devices may consume higher bandwidth.

In our illustration, the two PVCs we have are pppoe_0 _39_1 and br_0_35.

Click Add to create a new group.

Group Name:

Give a unique name here. The word length must not be over the length of the field. In our example, bridge.

Available Interfaces:

The available interfaces (such a s

Ethernet and USB) will be displayed in the left side box. When you choose i t and click Add, it will be transferred into the Grouped Interfaces at the right side box. Yet, if you want to remove the interface from the curre nt group, it will be returned back to the

Default group (left side box) after yo u click Remove.

Now we are going to map the Etherne t port with the bridge mode PVC. Click

br_0_35 and press Add button, the n press USB and click Add again. The two items are moved to the right box now.

After finish the settings, click Apply.


As you can see, we have a default group, in which PPPoE mode will be applied through Ethernet port and we have another group named bridge, in which bridge mode will be applied when connecting to the USB port.

You may click to edit the created group, press to delete it, or click Add to create another group.

105


The following relationship figure illustrates the port mapping configuration.

Under this configuration, a ny PC that connect to Ethernet port will connect to the internet through the bridge mode P VC pppoe_0_39_1, while the device using USB will access the internet by the PPPoE c onnection br_0_35.

TR-069 Client Configuration

TR-069 is a CPE WAN Management Protocol (CWMP) intended for communication between Customer Premise Equipment (CPE) and an Auto-Configuration Server

(ACS). It defines a mechanism that encompasses secure auto configuration of a

CPE, and also incorporates other CP E management functions into an integrated framework.

Using TR-069 the CPE can get in contact with the ACS and establish the configuration automatically. Accordi ngly other service functions can be provided.

TR-069 is the current standard for a ctivation of CPE in the range of DSL broadband market.

Compliant with D SL's Forum's TR-069 Remote Management Specification, the

ADSL Router is highly manageable w h dynamic service provisioning, firmware u pdates, status and performance monitoring, and diagnostics to a collection of ADSL routers. By these provision value-added services, the ADSL Router h effort as well as enhance customer satisfaction.

Normally, users do not have to modify the settings here. If you do not know how to set up, you can just accept the factory default settings on this page or contact your

ISP.

109


110

Connect to ACS:

Choose to connect to ACS with or without SSL (Secure Socket Layer) protocol according to your ISP.

If the ACS URL starts with http://, choose without SSL mode; if it begins with https://, select with SSL.

ACS URL Address:

Key in the Auto-Configuration Server

URL Address provided by the ISP, e.g., http://10.11.95.124:8082/askey/AC SS erver without SSL or https://10.11.95.124:8443/askey/ACS

Server with SSL.

ACS User Name/ ACS Password:

When connecting to ACS, this device must have correct user name and password for authentication. Key in the information provided by the ISP.

When the content of ACS URL

Address, User Name, and Password match the ACS authorization, the router will send an online report to

ACS.

Connection Request User

Name/Passw ord:

If the ACS wants to communicate with the device, it will have to offer the matching Connection Request User

Name and Password. When the device se nds the report to ACS for the first time, it will contain information for this.

Periodic Transmission of Inform

Request:

If this function is enabled, the CPE will frequently report to ACS the status after a period of time set here. The default setting is 300 seconds, and the

ISP can modify the value. Generally, users do not have to change the settings here.

If this function is disabled, the CPE will only report once when the connection between ACS and the device has been set up.

Identify the Validation of Certificate from ACS

When using SSL protocol to connect to ACS, a trusted CA and synchronic time setting with the server are used to identify the validation of the Certificate sent from

ACS.

When choosing with SSL for Connect

to ACS, you will see a paragraph appear on the bottom of the window

(as shown in the right column).

Press Trusted CA rt

Import Certificate obtained from you r

ISP, a window (as shown in the figur e) will be prompted for you to impor t certificate.

Note: The certificate may have been imported in this device already, plea se check with your ISP.

To synchronize your time with the server, go to Management->Internet

Time to adjust the setting. Configure to set time by Time Server, and make sure the time zone is the same as the server’s.

(Please refer to the next section for detailed information about Internet

Time.)


111


Internet Time

The clock of the router must synchroniz e with global Internet time. The time you set in the screen will be adapted to sys tem log.

Update Now:

Click this button to refresh the current time.

S et Time by (Time Server/ Manual):

T he default setting is Manual. Select this one, and set the start time by typing the date and the time manually to help the router perform tasks.

If you select Time Server, the system will set time via time server automatically.

Primary Time Server/ Secondary

System Log

As shown on the web page, you can view the system log and configure system log whene ver you want.

To view the system log, you must config ure system log first. Press

Configure System Log to start.

Configuring System Log

You can enable or disable the log function, and choose log level,

display level and proper mode as you like. Then click Apply to invoke the settings or press Cancel to discard them.

There are 8 types of log level and display level for you to choose.

Log Level:

This function en ables you to decide how detailed the messages will be stored. Set a proper level according to your needs. The default Log Level i s

Debugging .

The Debugging Level logs all messages to the file, while the

E mergency Level logs fatal m essages only. The lower the item is, the more detailed information it provides; i.e., debugging level stores the most detailed information.

Owing to the limitation of the storage on the ADSL router, the former information will be erased and replaced by the latest message automatically when the buffer is overflowed.

Display Level:

For the convenience of the users, the display level can function as a filter. It decides the level for the messages to exhibit when the user wants to view the logs on the local side. For example, for a programmer or engineer, he/she may want to know about debugging or informational level message; for general users, they may only need or want to learn about error,

critical, alert, or emergency messages only. The default Display Level is

Error.


113


Therefore, when the log level is

“Debugging” and the display level is

“Error”, the CPE logs the most detailed message but shows error level data only.

Mode:

You can choose where to store the logs; the options include Local,

Remote and Both. Local means t he

CPE, i.e., the ADSL Router. Remote means the log server you sp ecified to forward the log information to. The default mode is Local.

If you choose Remote or Both, you have to specify the Server IP

Address and UDP Port, and all the events will be s ent to the specified

UDP port of the specified log server.

Note:

Display Level only filters for the local side. All the messages will be displayed on the remote Log Server .

Example

Suppose we are going to record the system logs on both the ADSL Router and the

Server bearing IP address 10.11.95.2 , the procedures below illustrate the situation:

System Log Configuration

bugging as the Log

Level, and Error as the Dis play

Level. (Or select other leve l according to your needs.)

Server IP Address as 10.11.95.2, and leave the Server UDP Port as the default value 514. settings.

114


Viewing System Log – Remote Sid e (Server)

To view the system log on the Log

Server (10.11.95.2), a log viewing t ool must be installed.

1. Down load

Daemon from Kiwi Enterprises .

Kiwi Syslog Daemon is a freeware Syslog Daemon for

Windows. It receives, logs, displays and forwards Syslog messages from hosts such as routers, switches, and any othe r syslog enabled devic e. You can choose other logger tools; here, we use Kiwi for example.

Download the tool from the

Kiwi Enterprises website.

2. Install the Kiwi Syslog server software on the PC (10.11.95.2) .

3. Open the Kiwi Syslog Daemon application. You will get to a screen shown as follows.

1

2

The Date and Time record the logging time. The Priority field shows the log level, the Hostname exhibits the position of the host, and the Message column displays the process the description of it－before the colon is the name of the process and after the colon is the elaboration for that process.

For example, message 1 shows alert level information which is a kernel process containing detailed intrusion information; message 2 displays notice level information which is an IGMP process exhibiting that the IGMP function had been started.

115


Viewing System Log – Local Side (ADSL Router)

For viewing the system log on local side, click the View System Log button on the webp age for system log configuration.

Th e system log re cord on the router will be displayed on a screen shown as below.

4

The Date/Time records the logging time, and the Facility field

distinguishes different classes of system log message. The Severity field shows the log level, and the Message column displays the process and the description of it－the name of the process appears before the colon and the elaboration for that process after the colon.

For example, message 3 shows critical level information which is a pppd (PPP daemon) process showing that a valid IP address had been received from server, and connection is up; message 4 is a kernel process belonging to critical level information which reveals that the Ethernet 0 link is up.

You can press Refresh to update the log files or press Close to close the wind ow.

Chapter 5: Troubleshooting

Chapter 5: Troubleshooting

If the suggested solutions in this sect ion do not resolve your issue, contact your s ystem administrator or Internet service provider.

P roblems with LAN

PCs on the LAN cannot get IP addresses from the ADSL Router.

T he chances are that the interface used as DHCP server is modified and the client

P Cs do not renew IP addresses.

If your DHCP server is enabled on Private IP Address previously and you modify the in terface to Public IP Address, the client PCs should renew IP addresses.

T he PC on the LAN cannot access the Web page of the ADSL Router.

C heck that your PC is on the same subnet with the ADSL Router.

P roblems with WAN

You cannot access the Internet.

Check the physical connection between the ADSL Router and the LAN.

If the LAN LED on the front panel is off or keeps blinking, there may be problem on the cable connecting to the ADSL Router.

At the DOS prompt, ping the IP address of the ADSL Router, e.g., ping

192.168.1.1. If the following response occurs:

Reply from 192.168.1.1: bytes=32 time=100ms TTL=253

Then the connection between the ADSL Router and the network is OK.

If you get a failed ping with the response of:

Request timed out

Then the connection is fail. Check the cable between the ADSL Router and the network.

Check the DNS setting of the ADSL Router.

At the DOS prompt, ping the IP address of the DNS provided by your ISP. For example, if your DNS IP is 168.95.1.1, then ping 168.95.1.1. If the following response occurs:

Reply from 168.95.1.1: bytes=32 time=100ms TTL=253

Then the connection to the DNS is OK.

If you get a failed ping with the response of:

Request timed out

Then the DNS is not reachable. Check your DNS setting on the ADSL Router.

121


Problems with Upgrading

The following lists the error messages that you may see during upgrading and the action to take.

Error message: All the ADSL LEDs light up and cannot light off as usual.

Possible cause: When users are executing firmware upgrade or saving settings to the router, the power for the router is lost for some unknown reasons, the normal web page for the router might be damaged. After power on your router, the LEDs might not work normally.

122

Action: Setup you PC with a st atic IP address, such as 192.168.1.2, and then access the router’s web page by entering http://192.168.1.1

. Then update the firmware again.

Error Message: Image uploading failed. The selected file contains an illegal image.

Possible cause: The firmware file format is invalid.

Action: Check to see whether the file format is correct; otherwise download a firmware file with correct format.

ARP (Address R esolution Protocol )

ARP is a TCP/IP p rotocol for mapping an IP address to a physical machine address that is recognized in the local network, such as an Ethernet address.

A host wishing to obtain a physical address broadcasts an ARP request onto the TCP/IP network.

The host on the network that has the IP address in the request then replies with its physical hardware address.

Inverse ARP (In-ARP), on the other hand, is used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host's IP address.

DHCP (Dynamic Host Configuration Protocol)

When operates as a DHCP server, the ADSL Router assign IP addresses to the client PCs on the

LAN. The client PCs “leases” these Private IP addresses for a user-defined amount of time. After the lease time expires, the private IP address is made available for assigning to other network devices.

The DHCP IP address can be a single, fixed public IP address, an ISP assigned public IP address, or a private IP address.

If you enable DHC P server on a private IP address, a public IP address will have to be assigned to the NAT IP add ress, and NAT has to be enabled so that the DHCP IP address can be translated into a p ublic IP address. B y this, the client PCs are able to access the Internet.

LAN (Local a

A LAN is a comput er network limited to the immediate area, usually the same b uilding or floor of a building. A WAN, o n the other hand, is an outside connection to anothe r network or the Internet.

The Ethernet side of the ADSL Router is called the LAN port. It is a twisted-pair Ethernet

10Base-T interfac e. A hub can be connected to the LAN port. More than one computers, such as server or prin ter, can be connected through this hub to the ADSL Router and composes a L AN.

The DSL port of th e ADSL Router composes the WAN interface, which suppor ts PPP or RFC

1483 connecting t o another remote DSL device.

NAT (Netwo rk Address Translation) IP Address

NAT is an Internet standard that translates a private IP within one netw ork to a public IP address, either a static or dynami c one. NAT provides a type of firewall by hiding internal IP addresse s. It also enables a com pany to use more internal IP addresses.

If the IP addresses given by your ISP are not enough for each PC on the LAN and the ADSL

Router, you need to use NAT. With NAT, you make up a private IP network for the LAN and assign an IP address from that network to each PC. One of some public addresses is configured and mapped to a private workstation address when accesses are made through the gateway to a

For example, the ADSL Router is assigned with the public IP address of 168.111.2.1. With NAT enabled, it creates a Virtual LAN. Each PC on the Virtual LAN is assigned with a private IP address with default value of 192.168.2.2 to 192.168.2.254. These PCs are not accessible by the outside world but they can communicate with the outside world through the public IP 168.111.2.1.

Private IP Address

Private IP addresses are also LAN IP addresses, but are considered “illegal” IP addresses to the

Internet. They are private to an enterprise while still permitting full network layer connectivity between all hosts inside an enterprise as well as all public hosts of different enterprises.

123


The ADSL Router uses private IP addresses by assigning them to the LAN that cannot be directly accessed by the Internet or r emote server. To access the Interne t, private network should have an agent to translate the private IP address to public IP address.

Public IP Address

Public IP addresses are LAN IP addresses that can be considered “legal” for the Internet, because they can be recognized and accessed by any device on the other side of the DSL connection. In most cases they are allocated by you r ISP.

If you are given a range of fixed IP addresses, then one can be assigned to the router and th e others to network devices on the LAN, such as computer workstations, ftp servers, and web servers.

PVC (Permanent Virtual Circuit)

A PVC is a logical po int-to-point circuit between customer sites. PVCs are low-delay circuits because routing decisions do not need to be made along the way. Permanent means that the circuit is preprogrammed by the carrier as a path through the network. It does not need to be set up or turned down for each session.

UDP (User Datagram Protocol)

UDP is a connectionless transport service that dispenses with the reliability services provided by

TCP. UDP gives applications a direct interface with IP and the ability to address a particular applicatio n process running on a host via a port number without setting up a connection session.

Virtual Server

You can designate virtua l servers, e.g., a FTP, web, telnet or mail server, on your local network and make them accessible to the outside world. A virtual server means that it is not a dedicated server -- that is, the entire computer is not dedicated to running on the public network but in the private network.

VPI (Virtual Path Identifier) & VCI (Virtual Channel Identi fier)

A VPI is a 8-bit field while VCI is a 16-bit field in the ATM cell header. A VPI identifies a link formed by a virtual path and a VCI identifies a channel within a virtual path. In this way, the cells belonging to the same connection can be distinguished. A unique and separate VPI/VCI id entifier is assigned in advance to indicate which type of cell is following, unassigned cells, physical layer

OAM cells, metasignaling channel or a generic broadcast signaling channel. Your ISP should supply you with the values.
