Both – the router will incorporate routing information from adjacent routers, and will send adjacent routers it’s own routing table. • IP Multicasting – this feature enables or disables the router’s ability to route IP Multicast packets from one interface to another (for example, from the LAN ports to the ISDN port).
DI-1162 Remote Access Router LAN) where you wish the router to work with a device on the network that must act as a DHCP server. Otherwise, this feature should be kept disabled. • RIP Spoofing (WAN) – this feature should only be enabled if you have more than one router on your network and this router is providing your WAN connection.
DI-1162 Remote Access Router The parameters are described below: 40 • IP Address – this specifies the destination network IP address (or a host, depending on the netmask) and pairs it with a gateway. • Netmask – this mask shows how the destination IP address is to be divided into network, subnet and host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network and subnet parts, and zeros for the host part.
DI-1162 Remote Access Router IP Static Route Examples The IP Static Route Table shown in the example IP Static Route screen above has the first three entries configured for common implementations of static routing. The first entry assumes that WAN1 has a connection to the Internet and defines the default next hop router. If you use this router to connect to the Internet it is very important that you create an entry here that defines the default next hop router as your ISP.
DI-1162 Remote Access Router Router Advertisement When this option is enabled, the router will periodically send out ICMP packets that announce itself on the network. These ICMP packets are utilized by the Windows 98 or later operating system, which will automatically update the default gateway setting on the computer in which it is installed.
DI-1162 Remote Access Router SNMP Agent Configuration The Simple Network Management Protocol (SNMP), defined in STD 15, RFC 1157, is a protocol governing the management and the monitoring of IP network devices and their functions. The DI-1162 supports the use of SNMP to acknowledge communication between management stations and itself.
DI-1162 Remote Access Router The parameters are described below: • SNMP Community String – this community string is a userdefined identifying name used to group together some arbitrary set of SNMP application entities managed by the network manager. • Access Right – this element of the set { READ ONLY, READ/WRITE } is called the SNMP access mode. If the SNMP Community String has an Access Right of READ/WRITE, then that Community String is available as an operand for the get, set, and trap operations.
DI-1162 Remote Access Router The parameters are described below: • IP Address – enter the IP address of the host who will act as an SNMP Management Station. The DI-1162 router will send SNMP traps to these addresses. • SNMP Community String – the community string is a userdefined identifying name used to group together some arbitrary set of SNMP application entities managed by the network manager.
DI-1162 Remote Access Router SNMP Authenticated Trap Returning to the SNMP Agent Configuration menu, you can ‘Enable’ or ‘Disable’ an authentication failure trap message being sent to the Management Station by the router. When an SNMP packet with an invalid community name is received, it will be dropped. If this parameter is enabled, a trap will be sent to the network manager; if this parameter is disabled, no trap will be sent.
DI-1162 Remote Access Router Advanced Functions The Advanced Functions menu holds most of the more complex configuration settings and is shown below: Remote Access Configuration The Remote Access Configuration menu is used to set up the router for dial-in and dial-out connections through modems and/or ISDN devices attached to the WAN ports.
DI-1162 Remote Access Router to implement – we have described some of the basic functions and procedures below. Dial-In User Connections Dial-in users are defined as a single user on a computer, such as a person working at home, who dials into the office to use network resources. In almost all cases, a Dial-In User Profile needs to be set up for each user who will dial in to the router so the router can tailor the connection for each user.
DI-1162 Remote Access Router device is a router). In almost all cases, a Remote Network Profile needs to be set up for each network that will connect to the DI-1162 via a WAN connection. The Remote Network Profiles are necessary for the router to identify and tailor the connection to the remote network’s router. Once this is done, a connection between the two routers can be made and computers on each network can communicate with each other.
DI-1162 Remote Access Router I. In the case where the destination resides in the same IP network on the LAN, the routing engine never acts on the packet and it is sent directly to the destination through the LAN. II. In the case where the destination resides on a different IP network on the LAN (which can happen when Multiple Home Configuration is set up), the router will send out an ARP request to obtain the MAC address of the destination computer (or router) and deliver the packet.
DI-1162 Remote Access Router The Remote Access Configuration submenu is shown below. All items in the submenu are described as follows. Dial Configuration You can configure the two WAN interfaces on your DI-1162 to dial-out only when a packet is forwarded to that interface, and hang up after all data has been transferred and the link is idle. This can be used to lower the cost of an unpopular link or used as a backup link to your ISP. This feature is commonly called “Dial on Demand”.
DI-1162 Remote Access Router Dial In IP Pool The dial in IP pool allows you to define a range of IP addresses that will be reserved for and assigned to dial-in users. The items are described as follows: ♦ 52 IP Address – is the first IP Address that will be assigned to a dialin user.
DI-1162 Remote Access Router Range – is the number of IP Addresses that can be assigned. In the window shown above, dial-in users will be assigned the IP Addresses 170.100.200.1 or 170.100.200.2 (only two are necessary since the router used in the examples has only two WAN ports). WAN 1 This submenu contains a number of settings (shown below) which allow you to configure the router to dial out.
DI-1162 Remote Access Router will search for a Remote Network Profile that further configures this WAN port for dialing-out. Set Peer IP as Default Gateway – when enabled, this feature sets the IP address of the remote device as the default gateway (default next hop router) for all packets not found in the routing table. This option should be enabled for the WAN circuit (WAN1 or WAN2) that is used to connect to the Internet.
DI-1162 Remote Access Router The parameters in the above window are described as follows: • Name – the maximum length is 64 characters. This username is for password challenges (authentication). The user dialing in must supply this username in order to be allowed access to the router. • Password – this is the password associated with the above Name field. • Rem CLID – Remote Caller ID. This is the telephone number of the Remote User and is used for security.
DI-1162 Remote Access Router Dynamic - taken from the Dial In IP pool, or None - the remote user supplies his own IP Address. State – enables/disables this User Profile. Remote Network Profile The Remote Network Profile is used to configure the router for WAN connections to other networks. In practice, the DI-1162 will either dial-out to or receive incoming calls from another router, the ‘gateway’ to the other network.
DI-1162 Remote Access Router When this is set to Out, the router will only make calls on the WAN interface specified in the Interface field below. Also, the outgoing calls will be subject to the Name, Password and Phone Number fields in the Outgoing section below. When set to Both, the dial in and dial out conditions described above will both be observed. • Interface – WAN 1] or WAN 2. This field is used to assign a remote network to a logical (virtual) interface called a virtual circuit.
DI-1162 Remote Access Router • Outgoing • Name – the maximum length is 64 characters. Spaces and punctuation are not usually accepted. This username is for password challenges (authentication) which are automatically handled by the router when dialing out. The DI-1162 will use PAP and CHAP (whichever works) to make the connection. • Password – this is the password associated with the above Name field. • Phone Number – this is the telephone number that will be dialed to make the outgoing connection.
DI-1162 Remote Access Router Script File Configuration Script files are used on dial-out connections where the server you are connecting to uses a script for the logon procedure (common with many ISP’s). If you would like the router to automatically logon to a remote server, you must define a script file. Script files are executed immediately upon successfully establishing a connection. The DI-1162 can hold up to 8 different script files.
DI-1162 Remote Access Router Commands Script files can perform six Commands. You can choose the appropriate command by positioning the cursor in the Command field and pressing to toggle to the appropriate command. The script commands are defined as follows: 60 ♦ Wait – this command waits for text defined in the Parameter field to be transmitted by the ISP. In the above example, the router will wait for the ISP to prompt for ‘Username:’.
DI-1162 Remote Access Router • ^M – or . ♦ Delay – will delay for the number of seconds defined in the Parameter field. ♦ Get My IP – Will get the IP address from the ISP if the ISP sends it. This command is only valid for SLIP connections. ♦ Get Srv IP – Will get the Servers IP address if it is sent. This command is only valid for SLIP connections. ♦ End – Ends the script file.
DI-1162 Remote Access Router DHCP Server Configuration When acting as a DHCP server, the DI-1162 will manage many of the IP network parameters. The DI-1162 will never assign a broadcast or network IP addresses to hosts, even if such an address is included in the specified range. Please note that the router can act either as a DHCP Server or a DHCP Agent, but not both at the same time. Dynamic IP Pool The dynamic IP pool screen shown below contains the parameters that the router can set on the hosts.
DI-1162 Remote Access Router The parameters are described below: • IP Address – this is the base (starting) address for the IP pool of unassigned, IP addresses. • Range – this is the range of contiguous, IP addresses, above the base IP Address above. In the above example, the IP Addresses assigned would be 202.93.47.1, 202.93.47.2, … 202.93.47.100. • Netmask – this mask informs the client, how the destination IP address is to be divided into network, subnet and host parts.
DI-1162 Remote Access Router • DNS IP – this specifies the Domain Name System server, used by the DHCP clients using leased IP addresses, to translate hostnames into IP addresses or vice-versa. • WINS IP – this specifies the IP address of the Windows Internet Naming Service server. This server has software that resolves NetBIOS names to IP addresses. • Domain Name – this is the common suffix, shared by networked hosts, used to represent a common network domain.
DI-1162 Remote Access Router The parameters are described below: • IP Address – this is the static IP address to be assigned. • MAC Address – this specifies the physical address of the particular host that will receive the above IP address. All other parameters (Netmask, Gateway, DNS IP, WINS IP, State, & Domain Name) are identical to those in the Dynamic IP Pool configuration, in the previous section.
DI-1162 Remote Access Router • Time Threshold – this specifies the maximum amount of time (in seconds) since the host began requesting an IP address. If the value define here is exceeded, the relay agent will not pass along the request from the host. • State – enables/disables the DHCP Relay Agent function. Filter Configuration Your DI-1162 uses filters (configurable at two layers) to screen packet data, and apply a routing decision.
DI-1162 Remote Access Router The three sub-menus are described: 1. Filter State of Interface – this is used to choose the default, routing decisions for packets, not meeting the criteria for specific filters. 2. Layer 2 Filter – this is a data-link layer (protocol independent) filter. Foreknowledge of the specific protocol, used on the interface (LAN or WANs), is needed to make effective use of this filter. 3.
DI-1162 Remote Access Router that was applied to a specific interface, will be subjected to this default, routing decision. Each decision on handling packets is described below: 1. Disable – this does not apply a default, routing decision. 2. Forward – this allows the routing of a packet, even though it has not met the criteria of the corresponding filter. 3. Drop – this drops (doesn’t allow routing for) a packet that has not met the criteria for the corresponding filter.
DI-1162 Remote Access Router The parameters of a filter are described below: • Name – this is a 12 character (maximum), alphanumeric, userdefined name, used to identify the filter. • Direction – this defines the direction of the frame relative to the Interface parameter below. • State – this is used to choose the routing decision applied to the frame. The three decisions are described: 1. forward – this allows the routing of the frame, if it has met the criteria of the corresponding filter. 2.
DI-1162 Remote Access Router after the preamble. The range of the Offset parameter is from 0 to 255 octets. The first byte in a packet has an offset 0. • Length – this is the number of bytes (octets) from the offset value (the Offset reference byte). • Value – this is a 16 digit, hexadecimal field, defining the actual bit values used to compare with the frame data, at the specified (Offset + Length) position.
DI-1162 Remote Access Router • Name – this is a 12 character (maximum), alphanumeric, userdefined name, used to identify the filter. • Direction – this defines the direction of the packet relative to the Interface parameter below. • State – this is used to define the routing decision applied to the packet. The three routing decisions are described: 1. forward – this allows the routing of the packet, if it has met the criteria of the corresponding filter. 2.
DI-1162 Remote Access Router • Dst IP – this is the destination address in the IP header of the packet. • Dst Netmask – this mask is bit-wise AND’d with the destination IP address, and compared to the IP address of the outgoing interfaces. • Dst Port – this is the destination port, in the TCP or UDP header, of the packet. • Operation – this comparison operation is applied to the destination port (the Dst Port parameter) value, of the TCP or UDP header.
DI-1162 Remote Access Router Multiple Home can be demonstrated by this example: A company has 625 users (computers) all connected to one physical network using Ethernet. However, the company only has one Class C IP network address, 202.100.160.0. This network address will only support 254 users. To solve the shortage of IP address problem and to plan for future growth, the company applies for and receives two more Class C IP network addresses, 203.101.161.0 and 204.102.162.0.
DI-1162 Remote Access Router The parameters are described below: • IP Address – this is a network IP address, access point, to a separate, physical network, on the LAN. • Routing Protocol – this is the same as in the Network Configuration section. Keep in mind that these exchanges are made with adjacent routers on the LAN, if present. • IP Multicasting – this enables/disables IP multicasting on the IP network you are defining.
DI-1162 Remote Access Router Basically, when a packet comes into the router from a WAN port and is destined for a host on the LAN, the router will use information defined here to immediately send the packet to the host rather than send out an ARP request to find the host’s MAC address. The parameters are described as follows: • IP Address – this is the IP address that causes the router to reply with the MAC Address upon receiving an ARP request.
DI-1162 Remote Access Router NAT has two major benefits. First, NAT allows many users to access the Internet using a small number or even a single global IP address. This can greatly reduce the costs associated with Internet access and also helps alleviate the current shortage of Internet IP addresses. Secondly, the NAT process creates a firewall which hides your local network from Internet users, providing a degree of security to your Internet connection.
DI-1162 Remote Access Router sending and receiving data directly to the Internet and is therefore part of it. Please study the example diagram below carefully. Please note that in the above diagram, the Gateway IP address settings for the local PC’s needs to be set to 192.168.100.1, the LAN IP address of the router. NAT manipulates the IP addresses in packet headers on a one-to-one basis.
DI-1162 Remote Access Router In the Outgoing Data Packet above, the Source IP address is the IP address that is translated by NAT. The Destination IP Address is the IP address of a computer outside the private network, on the Internet for example. And the Data portion of the packet is the information payload borne by the packet, for instance a request to view a web page. The router logs the changes made to the IP header in its NAT table.
DI-1162 Remote Access Router NAT is the initial protocol set forth by RFC 1631 and provides a means in which private networks can communicate with the Internet by using a small number of IP addresses. In our discussion, we will use the example IP addresses listed in the table below and the network diagram shown at the beginning of this section. Global IP Addresses (for use with NAT) Local IP Addresses (assigned to computers on the local network) 200.100.50.1 200.100.50.2 200.100.50.3 200.100.50.4 200.
DI-1162 Remote Access Router made. Since there are only 5 global IP addresses in the example above, there can only be 5 mappings at any one time. In other words, much like static NAT, only 5 local machines can access the Internet at any one time.
DI-1162 Remote Access Router Configure NAT/NAPT The first screen shows the complete NAT table that is defined by the network manager: For any NAT entry, you must configure two different screens. The first one is accessible by positioning the cursor over the name field and hitting ENTER (in the window shown above, this corresponds to the field ‘Branch1’).
DI-1162 Remote Access Router you must save the changes, EXIT, and position the cursor over the NAT IP Pool to configure variables there. Name Field Configuration Screen The configuration screen for the name field appears as follows: The parameters are described as follows: 82 • Name – this is a 12 character, alphanumeric, user-defined name, used to identify the network address translation.
DI-1162 Remote Access Router Static NAT – Maps one global IP address to one local IP address. After all global IP addresses are assigned, they will remain static. This option may be necessary for email, web, ftp servers, etc. where static IP addresses are essential for operation. Dynamic NAT – Maps one global IP address to one local IP address. Global IP addresses will be dynamically reassigned to different local IP addresses if not currently being used.
DI-1162 Remote Access Router Dynamic NAT This screen (below) is how the NAT IP Pool appears, if Dynamic NAT was chosen for the Translation Mode parameter. Each entry, in this configuration, can be used to map multiple, contiguous global addresses and local addresses to each other. The parameters are described below: 84 • Global IP – an IP Address that is globally unique and valid on the Internet.
DI-1162 Remote Access Router • Range – this is the range of contiguous local addresses above (and including) the base Local IP. • State – this toggles the enable, disable, for this NAT entry. Dynamic NAPT This screen (below) is how the NAT IP Pool appears, if Dynamic NATPT was chosen for the Translation Mode parameter. Each entry, in this configuration, can be used to map a single global address and multiple, contiguous local addresses to each other.
DI-1162 Remote Access Router Static NAT This screen (below) is how the NAT IP Pool appears, if Static NAT was chosen for the Translation Mode parameter. Each entry in this configuration is used to map a single global IP address a single local IP address. The parameters are described as follows: • Global IP – this is a single, global IP Address that is valid on the Internet, or on the same subnet of the global interface. • Local IP – this is a single, local IP Address that is not valid on the Internet.
DI-1162 Remote Access Router address and port. Notice that the global address will be the external IP address of the global interface. • Port – this is a destination port number, used by TCP and UDP, to de-multiplex the incoming IP packet. In the above example, incoming packets with the global destination IP Address (211.11.22.2) and global destination TCP/UDP port (21) will be translated to a packet with the local destination IP Address (1.1.1.5) and local TCP/UDP port (21).
DI-1162 Remote Access Router numbers. The exact port number used is specific to the application. However, if you find that you are having trouble using an application over the Internet and you are using NAPT, you may need to exempt certain port numbers from the NAPT port translation process. Please refer to the user guide for the program to find out whether it transmits and receives data only through specified IP port numbers.
DI-1162 Remote Access Router The fields in the above window are described as follows: • Protocol – [UDP] or [TCP]. This field designates the type of packets that will be acted on. • Start Port – Some applications can only send data over a certain range of port numbers. Thus, all port numbers in the specified range must be exempt from the NAPT port translation process. This field defines the beginning range of the port numbers to be exempted from the NAPT port translation process.
DI-1162 Remote Access Router In the example for the game Diablo shown in the above screen, if a packet is sent out on the TCP port number 6112 (a request by a local user to a Diablo server on the Internet to join a group game), all incoming packets on the UDP port 6112 (game data) will not be translated by NAPT. Please keep in mind that the user will always initiate use of the special application. Thus, the first entry should always have the Connection Type of Outgoing Control.
DI-1162 Remote Access Router DNS Configuration The DI-1162 router has a built in recursive DNS server. The maximum amount of memory that will be used by the router’s Domain Name Server is 64Kb which averages out to be about 800 entries. In other words, up to 800 domain names and their associated IP Addresses can be stored, which can significantly speed up access to those domains.
DI-1162 Remote Access Router ♦ Lookup Host Table – enable/disables DNS to reference up to eight host names defined in the Host Table shown below. ♦ DNS Domain Name – the domain name suffix in which the router resides, to be appended to the host name defined in the host table. ♦ Forward DNS queries to – a large server dedicated to resolving domain names on the Internet. This field should contain the IP Address for the DNS closest to you.
DI-1162 Remote Access Router Items are described as follows: ♦ IP – The IP address for the host. ♦ Host Name – the name used by the host. ♦ State – Enables/disables entry. Radius Configuration Radius is a password protocol where passwords are stored on a Radius server. Radius allows large numbers of passwords to be stored in a centralized location. Before instituting Radius, please setup and install a Radius server on the LAN.
DI-1162 Remote Access Router Items in the above submenu are described as follows: ♦ RADIUS State – enables/disables Radius. ♦ Type – refers to the type of external password protocol. Currently, only Radius is supported. ♦ Server IP Address – this is the IP Address of your UNIX or NTbased Radius server. ♦ Port – the port number for the Radius server. The standard port number specified by RFC 1700 is 1812 (shown above). ♦ Key – this is a password used to identify the router as a valid Radius client.
DI-1162 Remote Access Router PPP Configuration Multi-Link PPP (MLPPP) Multi-link PPP (MLPPP) is a standard (RFC 1990 and RFC 1717) for inverse multiplexing, a method of combining individually dialed channels into a single, higher speed data stream. MLPPP is an extension of PPP that supports the ordering of data packets across multiple channels.
DI-1162 Remote Access Router second WAN port to place a call and add bandwidth to the WAN connection when the BOD High Threshold is exceeded for the Add Bandwidth Delay period. Bandwidth can also be subtracted when WAN throughput falls below the BOD Low Threshold and Subtract Bandwidth Delay parameters. Thus, BOD economizes MLPPP by maintaining only the bandwidth needed. A static implementation of MLPPP is achieved when BOD is disabled but the WAN ports have Multi-Link enabled.
DI-1162 Remote Access Router ♦ BOD Criteria – Either [TX], [RX] or [TX+RX], where TX is Transmit and RX is Receive. The parameter defined here is used when monitoring the BOD High Threshold and BOD Low Threshold. ♦ BOD High Threshold (%) – (0 to 100) The throughput value as a percentage of total bandwidth which will cause the next WAN port having Multi-Link PPP enabled to dial up and add bandwidth to the connection.
DI-1162 Remote Access Router RX) ever exceeds 80% of the 64kps (51.2kps), the router will sample the line for an additional 5 seconds. If the traffic continuously exceeds 80% for the 5 second delay time, WAN 2 will dial up and add bandwidth to the connection. Assuming sustained traffic of 70kps, MLPPP will balance the traffic on the two WAN ports so they are handling roughly 35kps each. If the traffic on WAN 1 + WAN 2 falls below 20% of the 128kps connection (25.
DI-1162 Remote Access Router Stac Compression – this is an industry standard 4:1compression scheme. When enabled, the router will try to use Stac compression on the designated WAN port whenever possible. If the destination device is not capable of using Stac compression, the two devices will still communicate, albeit without using Stac compression. When disabled, Stac compression will never be used on this port. Multi-Link PPP – Enables/disables multi-link PPP on this port.

Routing Table The Routing Table gives you a snapshot of the IP routing table.
DI-1162 Remote Access Router 104 • IP Address – this is the destination, network IP address from an incoming packet. • Netmask – this mask is received from RIP exchanges and internal calculations, as the router learns. • Gateway – this is the next-hop router for which the packet, with destination IP Address and qualifying Netmask, will be forwarded. • If – this is the outgoing interface for which the acceptable, routing packet will be forwarded. • Hops – this is the remaining hop-count.
DI-1162 Remote Access Router Counter This feature displays some of the counters contained in MIBII and the proprietary MIB. The table is updated every 5 seconds, and the counter table can be reset by performing a system reset on the router. Note that performing a system reset clears ALL tables in the router, including the routing table. LAN Counter Table ! Tx Packets – the total number of valid packets transmitted by the router since the last reset.
DI-1162 Remote Access Router to the shared nature of Ethernet. Excessive collisions show excessive utilization of the network. 106 ! Tx Abort Packets – When the router transmits a packet and a collision occurs, the router will wait a random period and try to retransmit the packet. If a collision occurs 16 times in a row, the transmission will be aborted and be logged by this counter. An aborted packet shows extremely heavy utilization of the network. ! Tx Underrun Packets – Runt packets.
DI-1162 Remote Access Router ! Rx MPA Packets – Missed Packet. This is a count of packets intended for the router, but at the time, the router could not receive the packet (usually due to the temporary lack of receive buffers). ! Rx DFR Packets – Deferred Packets. This is a count of incidents where CRS (carrier signal lost) and COL both occur at the same time. These two events happen simultaneously as a result of jabber (produced by faulty networking equipment, usually NIC’s).
DI-1162 Remote Access Router 108 ! Tx Underrun Packets – Runt packets. This counter shows the number of packets transmitted by the router that are less than the allowed 64 octets minimum length. Underrun packets occur due to jam signals generated by collisions, backpressure, etc. ! Tx Lost CTS Packets – the number of Clear To Send packets that were lost by the router. ! Rx Packets – the total number of packets received by the router.
DI-1162 Remote Access Router ! Rx CD Lost Packets – Carrier Detect Lost. This counts the number of Carrier Detect packets that were lost by the router. ! Rx Framing Error Packets – Packets with framing errors can occur on the WAN port only when using HDLC in sync mode. This parameter counts the number of lost start/stop flags. ! Rx Parity Error – the number of times parity errors occurred on the line.
DI-1162 Remote Access Router The parameters are described as follows: ♦ Code – A special code for categorizing events. Some codes include: • • • • • • • 0 1 2 3 4 5 6 Cold Start Link Change Tx Abort Rx Abort Connect/Disconnect NAT Request DHCP Request ♦ Port – The interface on which an event occurs. ♦ Time – Tick-times denoting when events occurred. ♦ Data – Data that helps technical support personnel evaluate the event.

Trace Buffer Configuration Enables/disables the Trace buffer feature. View Trace Buffer Displays the header of packets captured in the buffer. The contents are described as follows: ♦ Port – This is the interface from which the packets were captured. ♦ Time – in clock ticks. The time the packet was captured.
DI-1162 Remote Access Router Diagnostic This feature tests the connection between the router and connected peripherals on a given interface. Connection Test This feature tests a dial-out WAN connection.
DI-1162 Remote Access Router ♦ Interface – The WAN interface to be tested. ♦ Phone Number – The phone number that will be dialed by the WAN Interface. Please ensure that a modem answers the phone on the other end. ♦ Baud Rate – The rate of data transmission. The answering modem must be capable of operating at the baud rate defined here. ♦ Connection Test – Press to begin the test.
DI-1162 Remote Access Router Ping Test This test makes sure there is an IP network connection to a particular IP address. ♦ IP Address – This is the IP Address of the device that the router will attempt to reach. The router will check it routing table and try to locate the IP Address. ♦ Count – The number of pings (packets) that will be sent. ♦ Delay (10ms) – The amount of time in 10 millisecond intervals between each ping in the Count.
DI-1162 Remote Access Router System WAN Test The System WAN test is used to diagnose the WAN port. It can only be run if the WAN port is disabled in the Interface Configuration submenu.
DI-1162 Remote Access Router External Module Test This performs either a System LAN or System WAN test on the external module depending on which type of module is installed.
DI-1162 Remote Access Router Software Update New routing software can be downloaded from a TFTP server. If you do not have a TFTP server on your LAN, you can use the included Router Configuration Utility to upgrade the software. This Windows-based utility has a built-in TFTP emulator enabling you to use the computer (connected to the LAN and running the Configuration Utility) to upload the new software to the router.
DI-1162 Remote Access Router A system restart will not affect the router’s settings, but will clear all tables including the routing table and all SNMP counters and tables. It is also used to initiate a software update. Factory Reset Performing a factory reset erases all settings and tables. All configuration changes ever made to the router will be deleted. The router will be set to the factory defaults it was shipped with and will no longer have an IP address.
DI-1162 Remote Access Router Items in the window are described below: • Remote IP Address – this is the IP address of the TFTP server on which you wish to store the settings file. • TFTP Time Interval – the time between requests to occupy TFTP server time. If the router doesn’t receive a response (ACK) from the TFTP server within the time interval defined here, it will assume the request has been dropped and send another.
DI-1162 Remote Access Router PROM System Configuration The PROM program is run before the normal console (runtime) configuration program in the router’s Flash Memory. Thus, the PROM System Configuration can be used if there are problems with the router’s console program.
DI-1162 Remote Access Router System Configuration The parameters are described as follows: 122 ! Hardware Revision – this is the version ID of hardware used in this router. ! Boot PROM Firmware Version – this is the version ID of firmware used in this router. ! MAC Address – this is the physical address for this router.
DI-1162 Remote Access Router TCP/IP Parameters Configuration The parameters are described as follows: • Interface – the LAN interface must use Ethernet/Fast Ethernet and is displayed here. This setting cannot be adjusted. • IP Address – this is the router’s IP Address for the LAN interface. • Subnet Mask – this mask shows how the LAN is to be divided into network, subnet and host parts. • Default Gateway – this is the default gateway for the LAN.
DI-1162 Remote Access Router System Reset The system reset function enables you to reset the DI-1162 without powering off. Some settings changes require a system reset in order for them to take effect. A system reset will not affect the router’s settings, but will clear all tables including the routing table and all SNMP counters and tables. It is also used to initiate a software update. Software Update The Software Update option is used to change the software in the flash memory of the router.
DI-1162 Remote Access Router Items listed in the above menu are described as follows: • Software Update Control – this toggles disable, enable. • Software Update Mode – this specifies downloading the image file from a Network server on the local LAN. • Boot Protocol – this setting is for a local network download and has two options TFTP and BootP&TFTP. • TFTP – a File Transfer Protocol. Using this setting assumes all other items on this screen have been filled out.
DI-1162 Remote Access Router • Last Boot Server IP Address – this shows the last boot server used to download an image file. This is for reference only. • Last IP Address – this shows the last IP address used for the LAN interface. Again, this is for reference only. The LAN port must have an IP address in order to access the TFTP server via the LAN network. • Update Software from Configuration File – Either YES or NO.
DI-1162 Remote Access Router Please make sure you wish to wipe out all settings and configure the router from scratch before you perform a factory reset. Execute Bootload Choosing this option accepts the changes made in the PROM program and begins the router’s startup sequence. Executing a bootload can also begin the Software Update procedure, if enabled.
DI-1162 Remote Access Router Using Telnet The DI-1162 router can be configured and managed using telnet. Telnet accesses the same built-in configuration program as the RS-232 Diagnostic port console connection. As such, all settings that can be adjusted through the console can also be configured using Telnet. Telnet Configuration In order to use telnet, the DI-1162 router must first be configured using a console connected to the RS-232 Diagnostic port.
DI-1162 Remote Access Router The router can now be accessed via the LAN by the included Windows-based Configuration program, Telnet and SNMP management applications. For more detailed information regarding these procedures, please refer to the Connecting the Router section of this manual. For more information about the submenus, please refer to the Configuration and Management section of this manual.
DI-1162 Remote Access Router Using RADIUS Authentication In addition to the dial-in user list, which can hold up to eight users, this model also supports an external authentication server which may provide password storage and usage accounting for thousands of users. Installing a RADIUS Server To use RADIUS authentication, you will need to have a UNIX or Windows NT-based machine on your network to act as a radiusd server, as well as a copy of the radiusd server program itself.
DI-1162 Remote Access Router Items in the above submenu are described as follows: ♦ RADIUS State – enables/disables Radius. ♦ Type – refers to the type of external password protocol. Currently, only Radius is supported. ♦ Server IP Address – this is the IP Address of your UNIX or NTbased Radius server. ♦ Port – the port number for the Radius server. The standard port number specified by RFC 1700 is 1812 (shown above). ♦ Key – this is a shared secret used to identify the DI-1162 as a valid Radius client.
DI-1162 Remote Access Router 192.168.0.1 1234 should be added to the client file. The Client Name field in the file gives the IP address of the DI-1162, and the Key field should be the same as the Key field in the Radius Configuration submenu. After a RADIUS server has been configured, the DI-1162 will use it to authenticate all users instead of checking it’s internal Dial-Up User Profile.

DI-1162 Remote Access Router Appendix C - IP Concepts This appendix describes some basic IP concepts, the TCP/IP addressing scheme and show how to assign IP Addresses. When setting up the router, you must make sure all ports to be utilized on the router have valid IP addresses. Even if you will not use the WAN ports, you should, at the very least, make sure the LAN port is assigned a valid IP address.
DI-1162 Remote Access Router Networks attached to the Internet are assigned class types that determine the maximum number of possible hosts per network. The previous figure illustrates how the net and host portions of the IP address differ among the three classes. Class A is assigned to networks that have more than 65,535 hosts; Class B is for networks that have 256 to 65534 hosts; Class C is for networks with less than 256 hosts.
DI-1162 Remote Access Router The value(s) in the host portion of a physical device's IP address can be in the range of 0 through 255 as long as this portion is not all-0 or all-255. Values outside the range of 0 to 255 can never appear in an IP address (0 to 255 is the full range of integer values that can be expressed with eight bits). The network portion must be the same for all the IP devices on a discrete physical network (a single Ethernet LAN, for example, or a WAN link).
DI-1162 Remote Access Router IP Class Class A Class B Class C Subnet Mask 255.0.0.0 255.255.0.0 255.255.255.0 Subnet mask settings other than those listed above add significance to the interpretation of bits in the IP address. The bits of the subnet mask correspond directly to the bits of the IP address. Any bit an a subnet mask that is to correspond to a net ID bit in the IP address must be set to 1.
DI-1162 Remote Access Router Appendix D – IP Protocol and Port Numbers Common Internet service protocols and IP port numbers.
DI-1162 Remote Access Router Appendix E – Configuration File The router can be configured when performing a Software Update through a configuration file. The configuration file can hold many settings for the router including IP Addresses for all ports, path to the boot server, and various port settings. The configuration file is very useful if you wish to update your software and keep all or most of your settings the same. The configuration file should be saved with the extension .
