24 4.2 Interface Setup Click this item to access the follow ing sub - items that configure the ADSL router: Internet, LAN, and Wireless These functions are described in the following sections.
25 4.2.1 Internet ATM VC Virtual Circuit: VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a vi rtual circuit. VPI : The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This field may already be configured.
26 VCI: The valid range for the VCI is 32 to 65535. Enter the VCI assigned to you. This field may already be configured. AT M QoS: Select CBR to specify fixed (always - on) bandwidth for voice or data traffic. Select UBR for applications that are non - time sensitive, such as e - mail.
27 Dynamic Route: RIP Version: Select the RIP version from RIP - 1, RIP - 2B and RIP - 2M. RIP Direction: Select the RIP direction from None, Both, In Only and Out Only. Multicast: IGMP (Internet Group Multicast Protocol) is a network - layer protocol used to esta blish membership in a Multicast group - it is not used to carry user data.
28 4.2.2 LAN A Local Area Network (LAN) is a shared communicatio n system to which many computers are attached and is limited to the immediate area, usually the same building or floor of a building. Router Local IP IP Address : Enter the IP address of ADSL Router in dotted decimal notation, for example, 192.
29 If set to Enab le , your router can assign IP addresses, an IP default gateway and DNS servers to Windows 95, Windows NT and other systems that support the DHCP client.
30 4.2.3 for Wireless ADSL2+ Modem/router model only. This section introduces the wireless LAN and some basic configurations. Wireless LANs can be as simple as two computers with wireless LAN cards co.
31 which is already built - in to the router’s wireless interface. It is case sensitive and must not excess 32 characters. Make sure your wireless clients have exactly the SSID as the device, in order to get connected to your network . Broadcast SSID: Select Yes to hide the SSID in so a station cannot obtain the SSID through passive scanning.
32 Association). Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characte rs, for example, 00:AA:BB:00:00:02. You need to know the MAC address of the devices to configure this screen.
33 Encryption: TKIP (Temporal Key Integrity Protocol) uti lizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers. Pre - Shared key: The key for n etwork authentication. The input format is in character style and key size should be in the range between 8 and 64 characters.
34 the router that is the gateway to Internet. #: Item number Dest IP: IP address of the destination network Mask: The destination mask address. Gateway IP: IP address of the gateway or existing interface that this route uses. Metric: It represents the cost of transmission for routing purposes.
35 Metric : It represents the cost of transmission for routing purposes. The number need not be precise, but it must be between 1 and 15. Announced in RIP: This parameter determines if the Prestige will include the route to the remote node in its RIP broadcasts.
36 traffic is routed to appropriate WAN connections based on the destination IP addresses and Route Table. This eliminates the need for the static NAT session configuration between multiple LAN clients and multiple WAN connections. Virtual Circuit: VPI (Virtual Path Identifier) and VCI (Virt ual Channel Identifier) define a virtual circuit.
37 button is checked. Be aware that this IP will be exposed to the WAN/Internet. Sele ct the Apply button to apply your changes. Virtual Server In TCP/IP and UDP networks a port is a 16 - bit number used to identify which application program (usually a server) incoming connections should be delivered to.
38 Rule Index: Choose the rule number. S tart Port Number: Enter a port number in this field. End Port Number: Enter a port number in this field. Local IP Address: Enter your server IP address in this field.
39 Rule Index: Choose the rule number. Rule Type: One - to - on e: This is the mode maps one local IP address to one global IP address. Note that port numbers do not change for the One - to - one NAT mapping type. Many - to - One: This is the mode maps multiple local IP addresses to one global IP address.
40 One - to - one, Many - to - One and Server ma pping types. U sing port forwarding does have security implications, as outside users will be able to connect to PCs on your network. For this reason you are advised to use specific Virtual Server entries just for the ports your application requires , instead of using DMZ .
41 4.3.3 ADSL ADSL Mode: The default setting is Auto Sync - UP . This mode will automatically detect your ADSL, ADSL2+, ADSL2, G.dmt, G.lite, and T1.413. But in some area, multimode cannot detect the ADSL line code well. I f it is the case, please adjust the ADSL line code to G.
42 4.4 Access Management 4.4.1 ACL Access Control Listing allows you to determine which services/protocols can access which router interface from which computers. You can configure the router for remote Telnet access or upload and download router firmware and configuration files using FTP.
43 4.4.2 IP Filter You may use telnet or Web to remotely manage the ADSL Router. User just needs to enabl e Telnet or Web and give it an IP address that wants to access the ADSL Router. The default IP 0.0.0.0 allows any client to use this service to remotely manage the ADSL Router.
44 Source IP Address: The source IP address or range of packets to be monitored. Subnet Mask: It is the destination IP addresses based on above destination subnet IP Source Port Number: This Port or Port Ranges defin es the port allowed to be used by the Remote/WAN to connect to the application.
45 4.4.3 SNMP Simple Network Management Protocol (SNMP) is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. router supports SNMP ag ent functionality which allows a manager station to manage and monitor the router through the network.
46 4.4.4 UPnP UPnP offers peer - to - peer network connectivity for PCs and other network devices, along with control and data transfer betwe en devices.
47 4.4.5 DDNS The Dy namic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose ISP does not assign them a static IP address to use a domain name.
48 4.5 Maintenance 4.5.1 Administrator In factory setting, the default password is password , and that for user is also password. You can change the default password to ensure that someo ne cannot adjust your settings without your permission. Every time you change your password, please record the password and keep it at a safe place.
49 4.5.2 Time Zone The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server outside your network.
50 DO NOT power down the router or interrupt the firmware upgrading while it is still in process . Improper operation could damage the router. Warning 4.5.3 Firmware Your router’s “firmware” is the software that allows it to operate and provides all its functionality.
51 4.5.4 SysRestart Click Sys Restart with option Current Settings to reboot your router (and restore your last saved configuration). If you wish to restart the router using the factory default settin.
52 4.5.6 Diagnostics The Diagnostic Test page shows the test results for the connectivity of the physical layer and protocol layer for both LAN and WAN sides.
53 4.6 Status 4.6.1 D evice Info Device Information Firmware version: This is the Firmware version MAC Address: This is the MAC Address LAN IP Address: LAN port IP address.
