CHAPTER 3

Configuration Through Web The Web configuration is simple and easy to use. It will help in quick setting of the Router to connect to ISP (Internet Service Provider) with few steps required. It will guide user step by step to configure the various settings of GLB-502T.

3.1 INTERFACES

3.1.1 INTERFACES-LAN

The LAN Settings allows user to view the current IP address and subnet mask assigned to the Router. It also allows user to change these settings. If it is necessary to change the IP address or subnet mask assigned to the Router, enter the new values in the appropriate fields and then click apply to make the current changes.

For an example, if LAN network is to be a 192.168.1.x network with a subnet mask of 255.255.255.0, user might assign the Router an IP address of 192.168.1.1 and configure its DHCP server to assign addresses in the range between 192.168.1.2 to 192.168.1.254. The default gateway setting for computers on the LAN side will be the GLB-502T’s IP address which in this case is 192.168.1.1. Saving all of this information to the GLB-502T's flash will make this IP addressing scheme current. In Windows, when the user enables DHCP on the Network Interface Card he/she will obtain an IP address automatically.


3-2

Computers connected to the LAN port of GLB-502T will automatically be assigned an IP address(es) from the range 192.168.1.2 to 192.168.1.254. As an alternative, user could manually set the IP address, subnet mask and default gateway information for each computer on the LAN side.

It is recommended that if user needs to change the IP addressing scheme for the Router, he/she can configure it's DHCP server with the appropriate IP address range and subnet mask, and then assign an IP address from the same range. This way, a computer on the LAN side of network can always get the proper network addressing information by DHCP from the Router.

To change the IP address of the GLB-502T unit, go to

SETUP> LAN Configuration> Ethernet > Configure


3-3

The following will be displayed

By default the IP address of the GLB-502T is 192.168.1.1 and mask 255.255.255.0. To change the IP address the user must enter a new IP address, subnet mask if required and “Apply” the settings. The user must save the settings and must also change the IP address of the PC i.e. keep the PC IP address and subnet mask in the same range as that of the newly configured IP address. Now user can open the router’s web page with newly assigned IP address.

3.1.2 To set modulation on the GLB-502T go to

SETUP> Modem

Any of the modes mentioned above can be set.


3-5

3.1.3 WAN Interface A new WAN connection is a virtual connection over the physical DSL connection. Your GLB-502T can support up to eight different (unique) virtual connections. If you have multiple different virtual connections, you may need to use the static and dynamic routing capabilities of the GLB-502T to pass data correctly. Before you make a new WAN connection, you should make sure you have a DSL connection. For different WAN settings go to

SETUP> New Connection

3.1.3.1 To set the PPPoE settings select


Go to Type and select PPPoE PPP, or point-to-point protocol, is a method of establishing a network connection/session between network hosts. PPPoE is a


3-6

protocol for encapsulating PPP frames in Ethernet frames and is described in RFC 2516. 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 GLB-502T uses its own PPP stack. Access control, billing, and type of service control can all be done on a per-user rather than per-site basis. In PPP Settings the User will need to give the Username and password as given by the ISP (Internet Service Provider). Also set the VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) settings as per given by ISP. After giving the correct Username and Password the GLB-502T will get connected the PPPoE server at the ISP. The WAN side will be assigned an IP address automatically by the ISP and the user will be able to access internet.

3.1.3.2 To set the PPPoA settings select


Go to Type and select PPPoA.


3-7

PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets in ATM cells that are carried over the DSL line. PPP, or point-to-point protocol, is a method of establishing a network connection/session between network hosts. It usually provides a mechanism of authenticating users. Logical link control (LLC) and virtual circuit (VC) are two different methods of encapsulating the PPP packet. Contact your ISP to determine which encapsulation is being used on your DSL connection. In PPP Settings the User will need to give the Username and password as given by the ISP. Also set the VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) settings as per given by ISP.


3-8

3.1.3.3 To configure the router in Static Mode go to


Go to Type and select Static Static connection type is used whenever a known static IP address is assigned to the GLB-502T. Additional addressing information such as the subnet mask and the default gateway must also be specified. Up to three domain name server (DNS) addresses can be identified. These servers resolve the name of the computer to the IP address mapped to it and thus enable you to access other web servers by typing the symbolic name (host name). Here, the user can assign any name to the WAN connection. The user has to do the required settings as per given by the ISP. When using static mode, the LAN and the WAN IP addresses are configured in two different classes. Also the gateway of the PC connected to the LAN port of GLB-502T must be the LAN IP address of the GLB-502T unit.


3-9

3.1.3.4 To configure the router as a DHCP client go to


Go to Type and select DHCP

DHCP allows the GLB-502T to automatically obtain the IP address from the server. This option is commonly used in situations where the IP is dynamically assigned and is not known prior to assignment.


3-10

3.1.3.5 To configure the router as a Bridge, go to


Go to Type and select Bridge

A pure bridged connection does not assign any IP address to the WAN interface. NAT and firewall rules are not enabled. This connection method, as shown in makes the GLB-502T act as a bridge for passing packets between the WAN interface and the LAN interface.

The user has to set the correct VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) values as given by the ISP.


3-11

3.2 Advanced Settings To select advanced settings go to, ADVANCED from the main menu


3-12

3.2.1 To select UPnP connections go to

Advanced> UPnP

Universal plug and play (UPnP), NAT, and firewall traversal allow traffic to pass through the GLB-502T for applications using the UPnP protocol. This feature requires one active WAN connection. In addition, the PC should support this feature. In the presence of multiple WAN connections, select a connection on which the incoming traffic is present, for example, the default WAN connection.


3-13

3.2.2 To select SNTP connections go to

Advanced> SNTP

Simple network timing protocol (SNTP) is a protocol used to synchronize the system time to the public SNTP servers. It uses the UDP protocol on port 123 to communicate between clients and servers. When the SNTP feature is enabled, your GLB-502T starts querying for the time clock information from the primary SNTP server. If it fails to get a valid response within the Timeout period, it makes additional attempts based on the number specified in the Retry Count field before moving to the Secondary SNTP server. If it fails to get a valid response from Secondary STNP server within the specified retry count, it starts querying the Tertiary SNTP server. If it fails to get a valid response from all the servers, then the program stops. Once a valid response is received from one of the servers, the program goes to sleep for number of minutes specified in the Polling Interval field before starting the whole process again.


3-14

3.2.3 To configure Port Forwarding settings go to ADVANCED> Port Forwarding

Using the Port Forwarding page, you can provide local services (for example web hosting) for people on the Internet or play Internet games. To configure a service, game or other application select the external connection (for example the Internet connection), select the computer hosting the service and add the corresponding firewall rule. If you want to add a custom application, select the User category, click New and fill in the port, protocols and description for your application. You can also add/edit/delete rules without using the pre-defined Firewall Policy Database (games, services, etc.). Click on "Custom Rules" to access this type of interface. In the presence of the firewall, anonymous Internet traffic is blocked.


3-15

3.2.4 To configure the IP Filter settings go to ADVANCED> IP Filters

The IP filtering feature allows you to block specific applications/services based on the IP address of a LAN device. You can use the IP Filters to block specific traffic (for example, block web access) or any traffic from a host on your local network. A database of predefined IP filters allows you to apply one or more filtering rules to one or more members of a defined LAN group. You can view the rules associated with a predefined filter and add the available rules for a given category. You can also create, edit, or delete your own IP filter rules.


3-16

3.2.5 To configure LAN clients settings go to ADVANCED> LAN Clients

Using this feature user can see all the PCs on the LAN segment. Each PC is qualified to be either "dynamic" (PC obtained a lease from this router) or "static" (PC has a manually configured IP address). User can add a "static" IP address (belonging to the network segment of the router LAN IP address). Any existing static entry falling within dhcp server's range can be deleted and the IP address would be made available for future allocation. Once an IP address is allocated it shows up in the list of LAN clients as a "dynamic" entry. Any dynamic entry can be converted into static by using "reserve" checkbox. Note: Dynamic clients show up in the list only when DHCP server is running.


3-17

3.2.6 To configure LAN isolation settings go to ADVANCED> Lan Isolation

The LAN Isolation page allows you to disable the flow of packets between up to five user-defined LAN groups. This allows you to secure information in private portions of the LAN (such as a hot spot deployment) from other publicly accessible LAN segments.


3-18

3.2.7 To configure Bridge filter settings go to ADVANCED>Bridge Filters

The bridge filtering mechanism provides a way for you to define rules to allow or deny frames through the bridge based on source MAC address, destination MAC address, frame type, and physical ports. When bridge filtering is enabled, each frame is examined against every defined filter rule in sequence. When a match is found, the appropriate filtering action (allow or deny) is performed. Note that the bridge filter only examines frames from interfaces that are part of the bridge itself. Up to 20 filter rules are supported with bridge filtering. Steps to Configure 1) Check Enable Bridge Filters. 2) To add a rule, enter the source MAC address, destination MAC address, and frame type with desired filtering type, then click Add. Note—You can also edit a rule that you created using the Edit checkbox. You can delete a rule using Delete. 3) Click Apply to temporarily activate the settings.


3-19

Note—The changes take effect when you click Apply; however, if the GLB-502T configuration is not saved, these changes will be lost upon GLB-502T reboot. 4) To make the change permanent, click Tools and select System Commands. 5) On the System Commands page, click Save All.


3-20

3.2.8 To configure Dynamic DNS Client settings, go to ADVANCED> Dynamic DNS Client

Each time your GLB-502T connects to the Internet, your ISP assigns a different IP address to your GLB-502T. In order for you or other users to access your GLB-502T from the WAN-side, you need to manually track the IP that is currently used. The Dynamic DNS feature allows you to register your GLB-502T with a DNS server and access your GLB-502T each time using the same host name. The Dynamic DNS Client page allows you to enable/disable the Dynamic DNS feature. Steps to Configure : 1) On the Dynamic DNS Client page, configure the following fields: • Connection

• DDNS Server • DDNS Client • User Name • Password • Domain Name

3.2.9 To configure IGMP Proxy settings, go to ADVANCED> IGMP Proxy

Multicasting is a form of limited broadcast. UDP is used to send datagram’s to all hosts that belong to what is called a Host Group. A host group is a set of one or more hosts identified by a single IP destination address. The following statements apply to host groups: • Anyone can join or leave a host group at will. • There are no restrictions on a host’s location. • There are no restrictions on the number of members that may belong to a host group. • A host may belong to multiple host groups. • Non-group members may send UDP datagram’s to the host group. Multicasting is useful when the same data needs to be sent to more than one device. For instance, if one device is responsible for acquiring data that many other devices need, then multicasting is a natural fit. Note that using multicasting as opposed to sending the same data to individual devices uses less network bandwidth. The multicast feature also enables you to receive multicast video streams from multicast servers.


3-23

IP hosts use Internet group management protocol (IGMP) to report their multicast group memberships to neighboring routers. Similarly, multicast routers use IGMP to discover which of their hosts belong to multicast groups. Your GLB-502T supports IGMP proxy that handles IGMP messages. When enabled, your GLB-502T acts as a proxy for a LAN host making requests to join and leave multicast groups, or a multicast router sending multicast packets to multicast groups on the WAN side. Steps to Configure 1) Check Enable IGMP Proxy. 2) Configure the following interfaces: 3) Click Apply to temporarily activate the settings. Note: The changes take effect when you click Apply; however, if the GLB-502T configuration is not saved, these changes will be lost upon GLB-502T reboot. 4) To make the change permanent, click Tools and select System Commands. On the System Commands page, click Save All.


3-24

3.2.10 To configure Static Routing settings, go to ADVANCED> Static Routing

The Static Routing page enables you to define routes for specific subnets on the WAN/LAN side. The GLB-502T allows you to manually program the GLB-502T's routing table. Up to 16 static routes can be added. Steps to Configure 1) From the Choose a connection drop-down menu, select your LAN connection LAN Group 1. 2) Enter or leave the default entry for the following parameters: • New Destination IP: 10.0.0.0 (the network IP address of the subnet) • Mask: 255.255.255.0 (the subnet mask) • Gateway: 192.168.1.5 (the LAN-side IP address of the second router, through which the stations in the subnet access the network) • Metric: 0

You are telling the GLB-502T that a new subnet with an IP of 10.0.0.0 and a netmask of 255.255.255.0 has been added and can


3-25

access the GLB-502T via station 192.168.1.5. The metric is 0 since the subnet is one level down on the LAN.

3) Click Apply to temporarily activate the settings. You have added the subnet to the routing table. The four stations in the subnet can receive packets from the WAN. 4) Click Apply again when you finish making all the changes. Note—The changes take effect when you click Apply; however, if the GLB-502T configuration is not saved, these changes will be lost upon GLB-502T reboot. 5) To make the change permanent, click Tools and select System Commands. On the System Commands page, click Save All.


3-26

3.2.11 To configure Dynamic Routing settings go to ADVANCED> Dynamic Routing

The dynamic routing feature enables the GLB-502T 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 RIP-enabled router sends out automatic update packets containing its own routing table on a periodic basis (every 30 secs). Similarly, it accepts such periodic updates from other routers and adds, deletes, or modifies routes in its own routing table accordingly. The router is also expected to receive requests for its routing table and respond accordingly. Use the Dynamic Routing page to define dynamic routing routes for the available interfaces. Steps to Configure 1) Check Enable RIP. 2) Select the RIP Protocol RIP v2 for training purpose. The Enable Password field is enabled.


3-27

Note—The same RIP protocol should be used to enable dynamic routing on all routers on the network. 3) Check Enable Password and enter a password. This is an optional field for additional security. 4) For LAN group 1 and LAN group 2, leave Both checked in the Direction field. 5) Click Apply to temporarily activate the settings.

Notice you did not need to enter the subnet IP, mask, or gateway when using the dynamic routing feature. The GLB-502Ts can receive and transmit routing information and add it to their own routing tables.

6) Click Apply again when you finish making all the changes. Note—The changes take effect when you click Apply; however, if the GLB-502T configuration is not saved, these changes will be lost upon GLB-502T reboot. 7) To make the change permanent, click Tools and select System Commands. On the System Commands page, click Save All.

The Ingress page enables you to configure QoS for packets as soon as they come into the GLB-502T. This page is accessed by selecting Ingress on the Advanced main page. The domain mappings are converted to CoS (the common language) so that the priority marking is carried over. Steps to Configure 1) From Interface drop-down box, select PPPoE. You are configuring QoS on this WAN interface. 2) Select CoS1 in Class of Service and 5 in Priority Bits.

Any packets with priority marking 5 is mapped to CoS1, the highest priority that is normally given to the voice packets.

3) Click Apply to temporarily activate the settings. 4) Select CoS2 in the Class of Service field and 1 in the Priority Bits field.


3-31

Any packets that have a priority bits of 1 is mapped to CoS2, which is the second highest priority. This is given to the high priority packets such as video.

5) Click Apply to temporarily activate the settings. Note—The changes take effect when you click Apply; however, if the GLB-502T configuration is not saved, these changes will be lost upon GLB-502T reboot.

6) Repeat step 2-5 to add more rules to PPPoE1. Up to eight rules can be configured for each interface. Note—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. Note—Any WAN interface that is not configured has the default Untrusted mode.

8) To make the change permanent, click Tools and select System Commands. On the System Commands page, click Save All.

The remote log feature is used in conjunction with the PC tool (software provided with your GLB-502T). For PPPoE and PPPoA connections, you can select Debug in the Log Level field if you want to log the connection information. This is helpful when trying to debug connection problems. The remote log feature allows you to forward all logged information to one (or more) remote syslog server. The type of information forwarded to the remote server depends upon the Log level. Each log message is assigned a severity level, which indicates how seriously the triggering event affects GLB-502T functions. When you configure logging, you must specify a severity level. Log messages that are rated at that level or higher are sent to the syslog server and can be viewed using the syslog server application, which can be downloaded from the web or comes with a linux machine.

3.3.7 Modem Test For the modem test go to TOOLS> Modem Test

The Modem Test page is used to check the connectivity to the WAN. This test may take a few seconds to complete. Before running this test, make sure you have at least one WAN connection configured and have a valid DSL link. If the DSL link is not connected, the test will fail. Also make sure the DSLAM supports this feature. Not all DSLAMs have F4 and F5 support. F4/F5 cells are used for operation, administration, and maintenance (OAM) on ATM level. They are used for two main purposes: •Fault management (detection and notification) •Loop back testing and link integrity The ATM OAM is divided into several levels: •F4: VP level. OAM information flows between network elements (NEs) used within virtual paths to report an unavailable path or a


3-48

virtual path (VP) that cannot be guaranteed. Segment flows are processed, as well as end-to-end flows that terminate in the management processor. •F5: VC level. OAM information flows between network elements (NEs) used within virtual connections to report degraded virtual channel (VC) performance such as late arriving cells, lost cells, and cell insertion problems. Segment flows are processed, as well as end-to-end flows that terminate in the management processor. Both F4 and F5 flows can be configured as one of the test types :•Segment: This test verifies that ATM continuity exists between the virtual channel link segment from the GLB-502T to the DSL provider network (typically this is a DSLAM at the DSL provider site). •End-to-End: This test verifies ATM connectivity of the virtual channel link with the ATM endpoint, such as a remote broadband access router located at the DSL provider or ISP site.

3.4.5 QOS-TCA NTCA Status To view QOS-TCA NTCA Status go to STATUS> QOS-TCA NTCA Status

The QoS framework allows network administrators to configure the router to meet the real time requirements for voice and video. For a complete solution the QoS framework is supported on both the Ingress and Egress interface. The QoS Framework supports the following domains:- 1. TOS 2. DSCP To support these domains the QoS Framework introduces a virtual concept of Class of Service(CoS).There are six levels of service available named and prioritised as follows:- CoS1 > CoS2 > CoS3 > CoS4 > CoS5 > CoS6

The network admin needs to define Ingress TCA that maps the Domain to CoSx. The framework also allows the ability to classify


3-55

packets on the basis of the type of data. Currently the following fields can be used to classify packets:- 1. Source Mac Address 2. Source IP Address/Source Net 3. Destination IP Address/Destination Net 4. Source Port (Range is supported) 5. Destination Port (Range is supported) 6. Protocol Once a packet has been classified on the Ingress the network admin needs to configure the Egress to do the reverse i.e. CoSx to Domain Mappings.
