Chapter 3 The Web User Interface The 6381 A4 combination modem/router has a Wide Area Network (WAN) connection which connects to your phone line. This connects to your Internet Service Provider (ISP) via the phone line. The Local Area Network (LAN) connection is where you plug in your local computers to the router. The router is normally configured to automatically provide all the PCs on your network with Internet addresses.
The user name / password are Admin / Admin and both are case sensitive.
Home The first screen that appears after the log in screen is the Home page. From this screen you can configure the LAN and WAN connections, configure the router's security, routing, and filtering, access debugging tools, obtain the status of the router, and view the online help. The footer displays router status, connection information, and other useful information. Click Log Out to close the session, Refresh to update the status display, or Quick Start to configure basic options.
Quick Start The Quick Start screen gives you immediate access to the options you are most likely to need to specify or change. To access the Quick Start page, click the Quick Start button on the Home page. The Quick Start page gives you quick access to setting up three types of connections. See New Connection on page 33 for more connection options.
WAN Setup Before the modem will pass any data between the LAN interface(s) and the WAN interface, the WAN side of the modem must be configured.
PPPoE Connection Setup PPPoE is defined in the Internet standard RFC 2516. It is a method of encapsulating PPP packets over Ethernet. PPP (Point-to-Point Protocol) is a method of establishing a network session between network hosts. It usually provides a mechanism of authenticating users. PPPoE provides the ability to connect to a network of hosts over a simple bridging access device to a remote access concentrator. With this model, each 6381 remote gateway uses its own PPP stack.
5. To configure the connection sharing type, select Disable, Enable or VLAN from the Sharing drop down. Configure connection sharing as directed by your ISP. DSL creates a permanent virtual connection (PVC) between network endpoints. This connection may be shared where each device may have access to the packets, or the connection may be segregated. In other words multiple connections over the same PVC are supported. VLAN support requires that the ISP have VLANs supported and identified 6.
Debug Enables PPPoE connection debugging facilities. The Debug option is used by ISP technical support and ODM/OEM testers to simulate packets going through the network from the WAN side. PPP Unnumbered Specifies that the calling and answering routers will not request IP addresses. PPP Unnumbered is a special feature. It enables the ISP to designate a block of public IP addresses to the customer where it is statically assigned on the LAN side. PPP Unnumbered is, in essence, like a bridged connection.
VPI Virtual path identifier, equivalent to the virtual path connection (VPC). VCI Virtual channel identifier. A 16-bit field in the header of an ATM cell. The VCI, together with the VPI, is used to identify the next destination of a cell as it passes through to the ATM switch. QoS Quality of service, a characteristic of data transmission that measures how accurately and how quickly a message or data is transferred from a source host to a destination host over a network.
8. Select the Quality of Service (QOS). Leave the default value if your ISP did not provide this information. Depending on the QoS you select, you may also enter: • PCR (Peak Cell Rate) • SCR (Sustainable Cell Rate) • MBS (Maximum Burst Size) • CDVT (Cell Delay Variation Tolerance) 9. To complete the connection you must now click the Apply button. The Apply button will temporarily save this connection. To make the change permanent, click Tools (at the top of the page) and select System Commands.
PPPoA Connection Setup PPPoA is defined in the Internet standard RFC 2364. It is a method of encapsulating PPP packets over ATM cells which are carried over the DSL line. PPP (Point-to-Point Protocol) is a method of establishing a network session between network hosts. It usually provides a mechanism of authenticating users. LLC and VC are two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation is being supported.
The PPPoA connection setup page is displayed. 3. In the Name text box enter a unique name for the connection The name must not have spaces and cannot begin with numbers. 4. The NAT (Network Address Translation) and Firewall check boxes should be checked by default. NAT enables the IP address on the LAN side to be translated to IP address on the WAN side. If NAT is disabled, you cannot access the Internet.
Microsoft CHAP v2 is also supported with the Auto and CHAP options. However, MS CHAP v1 is not supported. 7. MTU The Maximum Transmission Unit the DSL connection can send. It is a negotiated value. The PPPoA interface default MTU is 1492 (max) and PPPoA default MTU is 1500 (max). The minimum MTU value is 64. On Demand Enables On Demand mode. The connection disconnects if no activity is detected after the specified idle timeout value.
Static Connection Setup A static connection is used whenever a known static IP is assigned. The accompanying information such as the subnet mask and the default gateway should also be specified. Up to three Domain Name Server (DNS) addresses can also be specified. These servers give you access to other web servers. The valid IP addresses range is from 1.0.0.0 to 223.255.255.254. To configure the router for a Static connection: 1. From the Home page, click Setup and then click New Connection.
4. Network Address Translation (NAT) and the Firewall options are enabled by default. Leave these options enabled. 5. In the Static Settings section, select the Encapsulation Type (LLC or VC) as supplied by your ISP. If you are not sure, just leave the default. 6. Enter your enter your assigned IP Address, Subnet Mask, Gateway, Default Gateway, and Domain Name Services (DNS) values as provided by your ISP. 7.
DHCP Connection Setup Dynamic Host Configuration Protocol (DHCP) allows the router to automatically obtain the IP address from the server. This option is commonly used in situations where IP is dynamically assigned and is not known prior to assignment. To configure the router for a DHCP connection: 1. From the Home page, click Setup and then click New Connection. The default PPPoE connection setup is displayed as the default setup. 2. In the Type dropdown select DHCP.
4. Network Address Translation (NAT) and the Firewall options are enabled by default. Leave these options enabled. 5. If your DSL line is connected and your DSL provider is supporting DHCP, you can click the Renew button and the router will retrieve an IP Address, Subnet Mask, and Default Gateway address. At any time you can renew the DHCP address by clicking on the Renew button. 6. In the PVC Settings section, enter values for VPI and VCI as supplied by your ISP.
Bridge Connection Setup A pure bridged connection does not assign and IP address to the WAN interface. NAT and firewall rules are not enabled. This connection method makes the RG act as a bridge for passing packets between the WAN interface and the LAN interface. To configure the 6381 as a bridge: 1. From the Home page, click Setup and then click New Connection. The default PPPoE connection setup is displayed. 2. In the Type dropdown select Bridge The Bridge connection setup page is displayed. 3.
5. In the Bridge Settings section, select the Encapsulation Type (LLC or VC) as supplied by your ISP. If you are unsure, just leave the default settings. Encapsulation The technique used by layered protocols in which a layer adds header information to the protocol data unit (PDU) from the layer above.
CLIP Connection Classical IP and ARP over ATM (CLIP) allow IP datagrams and ARP (Address Resolution Protocol) requests and replies to be transmitted over ATM using ATM Adaptation Layer 5 (AAL5). CLIP, defined in RFC 2225, provides the ability to transmit IP packets over an ATM network. The 6381’s CLIP support encapsulates an IP datagram in an AAL5 PDU frame using RFC 2225 and it uses an ATM-aware version of the address resolution protocol (ATMARP).
The name must not have spaces and cannot begin with numbers. 4. Select NAT and Firewall if you want them active for this connection. Firewall and NAT services must be enabled. 5. In the PVC section, select the VPI and VCI settings as provided by your ISP. For more information, please see PVC Settings from the PPPoE Setup procedure. 6. 7. Enter the IP address and subnet mask, the address of the ARP Server and the address of the Default Gateway as provided by your ISP.
Modify a Connection When you create a connection, the connection will be displayed in the WAN Setup section of the left navigation pane. To modify a connection: 1. From the top navigation bar, click Setup. 2. In the left hand navigation pane, select the connection you want to modify. The connections are listed by unique names given upon creation of the connection. 3. Make changes as appropriate 4. Click Apply The Apply button will temporarily save this connection.
Modem The Modem Setup page allows you to select any combination of DSL training modes including: • NO_MODE • ADSL_G.dmt (G Discrete Multi-Tone): G.dmt (G.992.1) • ADSL_G.lite: G.lite (G.992.2) • ADSL_G.dmt.bis • ADSL_2plus • ADSL_ANSI_T1.413 • Multi_MODE • ADSL_G.dmt.
LAN Setup On one side of your modem, you have your own Local Area network (LAN) connections. This is where you plug in your local computers to the modem. The modem is normally configured to automatically provide all PCs on your network with Internet addresses. The RG provides LAN configuration for multiple LAN bridge groups. Up to five LAN bridge groups are supported. The LAN interfaces could include: Ethernet, USB, and Bridge.
To configure the LAN: 1. From the Home page, click Setup and then click LAN Configuration. The LAN Configuration page is displayed. 2. To the right of the LAN group 1 field click Configure The LAN Group 1 Configuration page is displayed. 3. Set the LAN features: LAN configuration features: Unmanaged Unmanaged is a state when the LAN group is not configured and no IP address has been assigned to the bridge.
Netmask The default subnet mask of your RG is 255.255.255.0. This subnet allows the 6381 RG to support 254 users. If you want to support a larger number of users you can change the subnet mask. Default Gateway The default gateway is the routing device used to forward all traffic that is not addressed to a station within the local subnet. Your ISP provides you with the IP address of the default gateway. Host Name The host name is used in conjunction with the domain name to uniquely identify the RG.
Firewall / NAT Services The default setting for firewall and NAT services is enabled. Enable/Disable DHCP By default, the router has DHCP server (LAN side) disabled. If you already have a DHCP server running on your network, do not enable the router’s DHCP server. To enable DHCP: 1. From the navigation bar at the top, click Setup. 2. Under LAN Setup, select LAN Configuration. This will bring up the LAN Configuration Screen. 3.
4. Select the “Enable DHCP Server” radio button. 5. In the Start IP text box enter a Start IP address. The Start IP Address is where the DHCP server starts issuing IP addresses. This value must be greater than the router's IP address value. For example, if the router's IP address is 192.168.1.1 (the default) than the Start IP address must be 192.168.1. 2 or higher. 6. In the End IP text box enter the end IP address. The End IP Address is the last address the DHCP server can issue.
Changing the Router's IP address Your router's default IP address and subnet mask are 192.168.1.1 and 255.255.255.0, respectively. This subnet mask allows the router to support 254 users. Since the DHCP server issues a maximum of 255 addresses, there is not much advantage to changing the subnet mask to increase the number of addresses. Further, remember that if you change your router’s IP address and you have DHCP enabled, the DHCP configuration must reside within the same subnet.
Log Out To log out of configuration screen at any time 1. When the Setup, Advanced, Tools, Status, or Help screens are selected, click Log Out. From the Home page click the Log Out button. 2. Click the Save button to save your configurations and then click on Log Out to exit.

From the left hand navigation pane select UPnP. This will bring up the screen shown below. 3. Check Enable UPnP and then select which connection (WAN or LAN) will utilize UPnP. 4. Click Apply The Apply button will temporarily save this connection.
SNTP Simple network timing protocol (SNTP) is a protocol used to synchronize the system time to public SNTP servers. It uses the UDP protocol on port 123 to communicate between clients and servers. The 6381 supports SNTP client functionality in compliance with IETF RFC 2030. The system clock time in the 6381 can be configured to send client requests to the configured SNTP server addresses periodically.
3. Check Enable SNTP. 4. Specify one or more SNTP servers in the Primary SNTP Server, Secondary SNTP Server, and Tertiary SNTP Server fields and the SNTP options. 5. Primary SNTP Server The IP address or the host name of the primary SNTP server. This IP address can be provided by ISP or user-defined. Secondary SNTP Server The IP address or the host name of the secondary SNTP server. This IP address can be provided by ISP or user-defined.
Port Forwarding The port forwarding (or virtual server) feature allows you to direct incoming traffic to specific LAN hosts based on a protocol port number and protocol. Using the Port Forwarding page, you can provide local services (for example web hosting) for people on the Internet or play Internet games. When users send this type of request to your network via the Internet, the modem will forward those requests to the appropriate PC.

Dynamic Routing Dynamic Routing enables the 6381 RG to dynamically define routes for WAN and LAN subnets. Dynamic routing uses routing information protocol (RIP) for exchanging routing information with other routers in the network. It is supported across both WAN and LAN interfaces. Any RIPenabled router sends out automatic update packets containing its own routing table on a periodic basis (every 30 secs).
same protocol to be able to communicate with each other. The following procedure shows you how to enable and configure the dynamic routing feature on your RG. Enable RIP Enables/disables RIP. Protocol The following three RIP versions are available: • RIP v1 (UDP protocol) • RIP v2 (multicast protocol) • RIP v1 compatible (UDP protocol with multicast format) Note: Routers using RIP v1 or RIP v1-compatible protocol can talk to each other, but not to routers using RIP v2 protocol.
4. For additional security with RIPv2 check Enable Password and enter a password. Dynamic routing does not required the additional security. RIP v2 provides simple plain-text password-based authentication to RIP packets. The Enable Password field is disabled if RIP v1 protocol is selected. 5. From the Interface Direction drop down select the appropriate direction for each interface. Direction determines the direction that RIP routes will be updated.
Quality of Service (QoS) Quality of Service permits network administrators to prioritize how packets are handled, so that information with differing requirements, voice, video and data, will work properly. Network administrator configure routers to handle the different priority packets, however different networks use differing QoS marking. Note: QoS pages are for use by network administrators or Internet Service Providers (ISP).
Terms: • Ingress: Packets arriving into the RG from a WAN/LAN interface. • Egress: Packets sent from the RG to a WAN/LAN interface. • Trusted mode: Honors the domain mapping (ToS byte, WME, WLAN user priority). • Untrusted mode: Does not honor domain mapping. This is the default QoS setting. Forwarding rules based on CoS are: • CoS1 has absolute priority and is used for expedited forwarding (EF) traffic. This is always serviced till completion.
Policy Database The Policy Database page allows you to configure QoS for multiple WAN connections; you can classify packets based on fields in the packet. The Ingress and Egress pages allow you to configure QoS per interface. Fields that can be configured for setting policies: Field Description Ingress Interface The incoming traffic interface for a Policy Routing rule. Selections include LAN interfaces, WAN interfaces, Locally generated (traffic), and not applicable.
Source Port The source protocol port. You cannot configure this field without entering the protocol first. Destination Port The destination protocol port or port range. You cannot configure this field without entering the protocol first. Source MAC The MAC address of the traffic source. Local Routing Mark The Local Routing Mark field is enabled only when Locally Generated is selected in the Ingress Interface field.
Ingress Configure Quality of Service (QoS) for packets entering the device. Ingress denotes packets arriving into the 6381 from a WAN or LAN interface. The mappings are converted to CoS. QoS can be configured on a per interface basis. Select the interface — USB, Ethernet, Bridge — which needs to be configured. Ingress Untrusted Mode Untrusted is the default Ingress page setting for all interfaces. In this mode, no domain mapping is honoured in the RG.
The Apply button will temporarily save this connection. To make the change permanent, click Tools (at the top of the page) and select System Commands. On the System Commands page, click Save All. Ingress Layer 2 Configuration Layer 2 page enables you to map an incoming packet with VLAN priority to CoS. This feature is only configurable on the WAN interfaces as VLAN is only supported on the WAN side in the current software release.
The changes take effect when you click Apply; however, if the RG configuration is not saved, these changes will be lost upon RG reboot. 6. Repeat step 2-5 to add more rules to PPPoE1. Up to eight rules can be configured for each interface. Any priority bits that have not been mapped to a CoS default to CoS6, the lowest priority. 7. Repeat step 1-6 to create rules to another WAN interface. Any WAN interface that is not configured has the default Untrusted mode. 8.
Any incoming packet from LAN Group 1 (layer 3) with a ToS of 22 is mapped to CoS1, the highest priority, which is normally given to the voice packets. 3. Leave the default value CoS1 in Default Non-IP. Any incoming packet from LAN Group 1 without an IP is mapped to CoS1, the highest priority. 4. Click Apply to temporarily activate the settings. The changes take effect when you click Apply; however, if the RG configuration is not saved, these changes will be lost upon RG reboot. 5.
You are configuring QoS on this interface only. Any WAN/LAN interface that is not configured has the default Untrusted mode. 2. Select CoS1 in Class of Service. All incoming traffic from the Ethernet interface receives CoS1, the highest priority. 3. Click Apply to temporarily activate the settings. The changes take effect when you click Apply; however, if the RG configuration is not saved, these changes will be lost upon RG reboot. 4.
Ingress Interface This field is applicable for policy routing configuration only (see Policy Database) Destination Interface This field is applicable for policy routing configuration only (see Policy Database) DiffServ Code Point This field is applicable for policy routing configuration only (see Policy Database) Class of Service The selections are (in the order of priority): CoS1, CoS2, CoS3, CoS4, CoS5, CoS6, and N/A. Source IP The IP address of the traffic source. Mask The source IP netmask.
The field is applicable for policy routing only. 3. In the Class of Service field, leave the default CoS1. 4. In the Destination IP field, enter 192.168.1.5. 5. In the Destination IP Mask field, enter 255.255.255.255. 6. In the Protocol field, leave the default selection, TCP. 7. Click Apply to temporarily activate the settings on the page. The rule is generated at the bottom of the page. 8. To make the change permanent, click Tools and select System Commands.
Egress Egress denotes the direction of a frame exiting an interface. For outgoing packets the CoS marking needs to be translated to mapping understood by the network domains. No Egress The default Egress page setting. Domain mappings of the packets are not altered Layer2 Enables you to map an outgoing packet to user priority bits which are honoured by the VLAN bridged network. Only supported on WAN interfaces.
Egress Layer 2 Configuration The Egress Layer 2 feature enables you to map the CoS of an outgoing packet to user priority bits, which is honored by the VLAN network. This feature is available on the WAN interface only. Interface Select the WAN/LAN interface here to configure the QoS for outgoing traffic to the IP network. Default Non-IP Locally generated packets (such as ARP packets) do not have a CoS marking. You can define the CoS for all unclassified outgoing packets on layer 3 using this field.
WLAN QoS Support The WLAN QoS is supported; however, it is hard-coded and is not configurable on the Ingress and Egress pages. User Priority Class of Service WME Priority DSCP Map 0 (Best-Effort) CoS5 0 0 (0x0) 1 (Background) CoS6 1 8 (0x20) 2 (Background) CoS6 2 16 (0x40) 3 (Best-Effort) CoS5 3 24 (0x60) 4 (Video) CoS2 4 32 (0x80) 5 (Video) CoS2 5 40 (0xA0) 6 (Voice) CoS1 6 48 (0xC0) 7 (Voice) CoS1 7 56 (0xE0) There is no shaper support on WLAN interface.
CoS2 is configured for 100Kbs and CoS6 for 300Kbps, CoS2 takes 100Kbps when there are no CoS1 packets. CoS6 can take 300Kbps when there are no CoS1 or CoS2 packets. PRIOWRR Queues CoS2 to CoS6 are serviced round robin. CoS1 has the highest priority and is not controlled by the WRR data shaping algorithm. PRIOWRR does not use Max Rate. Percentages of packets received are sent out. CoS2 to CoS6 will not be serviced while there are CoS1 packets. CoS2 to CoS6 will share based on the percentages of the packets.
Example 2: Low Latency Queue Discipline Enabled In this example Low Latency Queue Discipline is enabled. CoS1 is not rate controlled (hence the field is disabled). CoS2 takes 100 kbits when there are no CoS1 packets. CoS6 has 300 kbits when there are no CoS1 or CoS2 packets. This is similar to the HTB queue discipline as they are both rate-based algorithm, except that CoS1 is handled differently. Example 3: PRIOWRR Enabled In this third example, PRIOWRR is enabled.
Access Control The Access Control page provides a means to allow Telnet, Web, FTP (file transfer protocol) or TFTP (trivial FTP) access to the 6381 RG for devices which are either on the WAN or LAN sides of the 6381 RG. When Enable Access Control is checked, the devices in the IP Access List, designated by their IP Addresses will have the access defined in the WAN or LAN group 1 column. To configure access to the 6381 RG: 1. From the navigation bar at the top of the screen click Advanced 2.
5. Click Apply 6. To enable access to a device outside your network (on the WAN side of the 6381 RG), select the Telnet, Web, FTP or TFTP options for WAN, and add the IP for that address to the IP Access List 7. Click Apply The Apply button will temporarily save this connection. To make the change permanent, click Tools (at the top of the page) and select System Commands. On the System Commands page, click Save All.

Chapter 6 Troubleshooting The Router Is Not Functional 1. Check to see that the power LED is green and the network cables are installed correctly. Refer to the quick start guide for more details. 2. Check to see that the LAN and Status LEDs are green. 3. Make sure you are not connecting the USB and the Ethernet port to the same PC at the same time. 4. Check the settings on your PC. Again, refer to the quick start guide for more details 5. Check the router's settings. 6.
The Status LED is Always Off 1. Make sure you have DSL service. You should receive notification from your ISP that DSL service is installed. You can usually tell if the service is installed by listening to the phone line: you will hear some high-pitched noise. If you do not hear high-pitched noise, contact your ISP. 2. Verify that the phone line is connected directly to the wall and to the line input on the router.
Nslookup You can use the nslookup command to determine the IP address associated with an Internet site name. You specify the common name, and the nslookup command looks up the name in on your DNS server (usually located with your ISP). If that name is not an entry in your ISP’s DNS table, the request is then referred to another higher-level server, and so on, until the entry is found. The server then returns the associated IP address.

DHCP Dynamic Host Configuration Protocol DHCP automates address assignment and management. When a computer connects to the LAN, DHCP assigns it an IP address from a shared pool of IP addresses; after a specified time limit, DHCP returns the address to the pool.
but if something happens to your engine, you are protected. The firewall in the router is very similar. Only the connections that you allow are passed through the firewall. These connections normally originate from the local network, such as users web browsing, checking email, downloading files, and playing games. However, you can allow incoming connections so that you can run programs like a web server.
LAN Local Area Network. A network limited to a small geographic area, such as a home or small office. LED Light Emitting Diode An electronic light-emitting device. The indicator lights on the front of the device are LEDs. MAC address Media Access Control address The permanent hardware address of a device, assigned by its manufacturer. MAC addresses are expressed as six pairs of hex characters, with each pair separated by colons. For example; NN:NN:NN:NN:NN:NN. Mask See network mask.
PPP Point-to-Point Protocol A protocol for serial data transmission that is used to carry IP (and other protocol) data between your ISP and your computer. The WAN interface on the device uses two forms of PPP called PPPoA and PPPoE. See PPPoA, PPPoE. PPPoA Point-to-Point Protocol over ATM One of the two types of PPP interfaces you can define for a Virtual Circuit (VC), the other type being PPPoE. You can define only one PPPoA interface per VC.
suite of protocols. Telnet An interactive, character-based program used to access a remote computer.
