9 Chapter 1 About Internet Router 1 This Chapter provides an overview of the Internet Router's features and capabilities. The Internet Router allows multiple SOHO (Small Office Home Office) users to share a single Internet user account (IP address) over an ISDN phone link. It provides a low-cost method of giving users of your network easy access to the vast resources available on the Internet. Internet Router Features Figure 1: Office to Internet The Internet Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. LAN Features 10/100 BaseT Support. The LAN connection will auto-detect 10BaseT and 100BaseT connections DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Internet Router can act as a DHCP Server. 1

10 Internet Router User Guide Multi Segment LAN Support. If you have a Router, PCs on other LAN segments can use the ISDN Internet Router to access the Internet. A static routing table is provided to support multiple routers if needed. Internet Access Features Shared Internet Account. All users on the LAN can share the same Internet Account (IP address). Dial-On-Demand & Auto-Disconnect. A connection is established to the Internet as required, and automatically disconnected when no longer needed. This reduces on-line charges to the minimum possible level. PPP Authentication. This is used to validate the log-on to your Internet Service Provider. Advanced Internet Functions. Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. User-Defined Virtual Servers. Internet users can access non-standard Internet Servers on your LAN by using this feature. Special Internet Applications. Internet applications such as Internet Videoconferencing, Telephony, Games Servers, and other specialpurpose Servers are supported. Exposed Computer. One (1) PC on your local LAN can be exposed to the Internet. This allows unrestricted 2-way communication between this PC and servers or users on the Internet. ISDN Features Easy Configuration. No complex technical data or unintelligible prompts. You ll be finished in minutes! Intelligent B Channel Utilization. Internet access will automatically switch between 1 or 2 B channels, depending on the volume of data. Outgoing call ID. The Internet Router supports Outgoing call ID for both MSN (Multiple Subscriber Numbering) and SAD (Sub Address). 2

11 About Internet Router Configuration & Management Easy Setup. Use your WEB browser from anywhere on the LAN for configuration. Remote Management. The Internet Router can be managed, if required, from a workstation anywhere on the LAN, using a WEB browser. A friendly utility in MS Windows does the advance setup to achieve functions and performance. Remote Monitoring. Internet access via the ISDN link, can be monitored from any workstation on the LAN. Advanced Functions Dial-in Remote Access. Remote users can dial in using their ISDN phone line, and use the ISDN Internet Router to connect to the LAN and access LAN resources.. LAN-to-LAN Connectivity. Using 2 ISDN Internet Routers, 2 LANs can be connected via the ISDN link. The ISDN Internet Router will dial the remote LAN whenever required. Operation is completely automatic and transparent. Security Features Configuration Data. Optional password protection is provided to prevent unauthorized users from modifying the configuration. Firewall Protection. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. Firewall Protection The firewall protection provided by the Internet Router is an intrinsic side effect of IP sharing. All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device. 3

12 Internet Router User Guide For internal users, the Internet Router acts as a transparent proxy server, translating the multiple internal IP addresses into a single external IP address. For external requests, any attempt to connect to local resources are blocked. The Internet Router will not reverse translate from a global IP address to a local IP address. This type of natural firewall provides an impregnable barrier against malicious attacks.

16 Chapter 2 Setup: Internet Router 2 This Chapter explains how to install and configure the Internet Router for Internet Access. Overview Setup involves: Hardware Installation Internet Router configuration PC configuration Hardware Installation 1. Connect Network Cables Use standard UTP network cable, with RJ45 connectors, to connect the ISDN Internet Router to a 10BaseT or 100BaseT hub. The ISDN Internet Router will auto-detect the network speed (10M or 100M) and full/half duplex mode. 2. Connect ISDN Phone Line Using a cable fitted with RJ45 plugs, connect the ISDN port on the Internet Router to the S/T interface on the ISDN NT-1 (Network Termination 1). 3. Power On and Check the LEDs Connect the supplied power adapter to the Internet Router. When the Internet Router is powered On, all LEDs should blink, then, except for the PWR LED, go off. If LAN and ISDN connection is working fine, the LNK and LK leds will stay ON. 8

17 Setup: Internet Router If the ERR LED stays on, or both the ERR and LNK LEDs continue to blink, there is a hardware problem. Warning! Only use the power adapter provided. Using a different one may cause hardware damage. Internet Router Configuration There are two methods to configure the Internet Router, one is using web browser and the other is using utility working in Win95/98/NT. The browser configuration provides a quick start configuration (only one screen) and an extra utility provides more powerful configuration for users. But first of all, please make sure that the default IP address, is used by Internet Router ONLY at the first stage until you change it to another one after configuration. Web Browser Configuration Preparation Ensure Internet Router is in the LAN, your PC is using the TCP/IP protocol, and configure PC to use the Internet Router s DHCP server, as fo llows: DHCP Client Setup - Windows 95/98 and use Internet Router DHCP server 1.

Other Setup Except in the following circumstances, no other configuration is required. 22

31 Setup: Internet Router If using an existing DHCP Server: Configure it to provide the ISDN Internet Router's IP Address as the Default Gateway. The DHCP Server in the ISDN Internet Router should be disabled. This setting is on the LAN Tab of the Manager utility. ISDN Router's DHCP Server Settings unsuitable If your LAN already has some devices using fixed IP Addresses, you need to set the IP Address range used by the DHCP Server to be compatible. The DHCP Server settings are on the LAN Tab of the Manager utility. Your LAN has a Router The Routing feature can be completely ignored if you do not have a router in your LAN. If you DO have a router, it is necessary to configure BOTH the Router and the Routing table in the ISDN Internet Router correctly. See Routing for details. Default ISDN Settings unsuitable In rare cases, it may be necessary to change the ISDN settings (B Channel Speed, Initialization string). These settings are on the ISDN Tab screen. This screen also allows you to: Temporarily switch the ISDN link OFF. Use 2 B Channels for Internet access, rather than 1. Set the outgoing call MSN and SAD. (MSN and SAD allow you to have multiple phone numbers). Once setup is complete: Restart the ISDN Internet Router by disconnecting and reconnecting the power. Refer to the next document (LAN/PC Setup) for details on setting up each PC, including the one used for configuration. 23

32 Internet Router User Guide Status Screen The Status tab on the Windows utility can be used to review the current settings and operation of the ISDN Internet Router. An example screen is shown below. 24 Figure 10: Status Screen

This will occur at the end of a session, or an error condition. Idle timer expires The "Idle time-out" has been triggered. (There was no data sent or received for the duration of the "Idle time" period.) 26

35 Password Screen The password protects the ISDN Internet Router's configuration data. If a password is not set, anyone can connect to the ISDN Internet Router and change its configuration. If the password is lost, a DIP switch setting is provided to clear the password. Refer the RESET THE DEVICE for more information. Selecting the Password tab will reveal a screen like the example below. Figure 11: Password Screen 27

36 Internet Router User Guide Enter the password on this screen: Passwords are case sensitive and can be up to 8 alphanumeric characters (no spaces or punctuation). To create or change the password, enter the required password in both the New Password and Verify Password input fields. 28

37 LAN Screen Unless your LAN has a Router, it is usually unnecessary to change the settings on this screen. An example screen is shown below. This screen has 3 sections relating to the LAN on which the ISDN Internet Router is installed. DHCP Server Routing Table DNS (Domain Name Server) IP Addresses Figure 12: LAN Screen 29

38 Internet Router User Guide DHCP Server A DHCP (Dynamic Host Configuration Protocol) server provides a valid IP address, Gateway address and DNS addresses to a DHCP client (PC or device) upon request. The ISDN Internet Router can act as a DHCP Server. The default value is ON (Enabled), and use of this feature is strongly recommended. To use this feature, ensure that Enable is checked. Also, the PCs must be configured to act as a DHCP clients. See above DHCP Client Setup section of Web Browser Configuration for details of this procedure. IP Address allocated by the DHCP Server Normally, the default values for the DHCP Server do not need to be changed. However, if your LAN already has some devices using fixed IP Addresses, you must ensure that each of those devices uses an IP Address which is compatible with the IP Addresses allocated by the DHCP Server. "Compatible" means: o o o The IP Address is from the same address range as the DHCP Server. By default, the ISDN Internet Router uses the IP Address range to The IP Address must NOT be within the group allocated by the DHCP Server. By default, the ISDN Internet Router allocates addresses between to Therefore, addresses between and are available for other devices. All devices must use the same Network Mask (Subnet Mask). If you have non-pc devices on your LAN, it may be more convenient to change the IP Addresses allocated by the DHCP Server function in the ISDN Internet Router, rather than change the IP Addresses used by the existing devices. To do this: 30

39 Setup: Internet Router Routing Table 1. For the Start IP Address, enter the first IP Address of the range of IP Addresses to be allocated by the DHCP Server. 2. In the End IP Address, enter the last IP Address of the range of IP Addresses to be allocated by the DHCP Server function. 3. Ensure that the range is large enough for all of the PCs and devices which will be acting as DHCP clients and requesting an IP Address. The default number of clients is 50; the maximum is 253. This is a static Routing Table. Entries are required only if your LAN contains 1 or more Routers. See Chapter Routing for further details. If you are using the ISDN Internet Router for LAN-to-LAN connectivity, an entry will automatically appear here for the remote LAN you are connecting to. Do NOT delete this entry. DNS (Domain Name Server) IP Address Space is provided for 3 entries. The first entry will display the DNS value entered on the Quick Setup screen. Enter additional values if you wish. If multiple entries are provided, the first available DNS will be used. 31

40 Dial-In Access Screen The ISDN Internet Router's dial-in feature allows remote users to: Use an ISDN TA to connect to the ISDN Internet Router, using the same PPP communication software (e.g. Dial-up Networking) that they use for dial-in Internet access. Have their user name and password verified by the ISDN Internet Router. (Note: If dial-in PPP link security is set to "None", no verification is performed.) Access the LAN resources as if they were a local user. To other users on the LAN, the remote users appear to be a local PC, using the IP Address allocated by the ISDN Internet Router. For additional security, the dial-back function can be used. In this situation, the ISDN Internet Router will hang-up the user's incoming connection, and then call them back. To use the Dial-in Feature: 1. Dial-in must be Enabled on the Dial-in Tab. 2. User access data is required. The options are as follows: o o o Allow access by anyone and everyone (not recommended) - If Authentication on the Dial-in screen is set to None, then the user name and password is not checked, so anyone who dials in can gain access. All users use the same log-in - Create a single user (on the Dialin screen) with dial-in access, and all users use this log-in. Enter data for each user - Each person requiring dial-in access has their data entered on the Users screen. 3. The remote user can use the same dial-up software they use for Internet access. Once connected, the remote user can access LAN resources as they normally would. They will appear to other LAN devices as a normal PC on the LAN, using the IP Address allocated by the ISDN Internet Router. 32

41 Setup: Internet Router Data - Dial-in Access Dial-in Access Figure 13: Dial-In Screen Enable Dial-in Access Idle Time-out If checked, dial-in will be allowed. Otherwise, any attempt to dial-in will be blocked. If a dial-in connection remains inactive, it is terminated after this time period. Allowable range is 0-99 minutes; 0 means no 33
