Chapter 3
Other Configuration

This Chapter details other configuration possibilities and options which are not normally required.

LAN - DHCP

A DHCP (Dynamic Host Configuration Protocol) Server provides an IP address and related data to a DHCP Client (PC or device) upon request.

Existing DHCP Server

If using an existing DHCP Server, rather than the DHCP Server in the ISDN Internet Router, the following changes are required:

ISDN Internet Router's DHCP Server

Normally, the default values do not need to be changed. However, 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.

Enable/Disable
Enable/Disable the DHCP Server.
Start IP Address
Finish IP Address
Sets the addresses allocated to DHCP clients by the DHCP server.
This also sets the number of DHCP clients - maximum is 253.
DNS IP Address
If multiple entries are provided, the first available DNS will be used.

Devices having fixed (static) IP Addresses must NOT use an IP Address within the range used by the DHCP Server.

LAN - Routing

The Routing feature (on the LAN tab) 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 Chapter 4 - Routing for further details.

ISDN

The ISDN tab on the Manager program is shown below.

Figure 8: ISDN Tab

In most situations, there is no need to change these settings.

Usage
These settings determine how the 2 ISDN "B" channels are used for Internet access:
  • Always use 1 B Channel. This is the default setting, and leaves 1 B channel available for Dial-in.
  • Dynamically use 2 B Channels. This setting uses 1 or 2 B Channels for Internet access, depending on the traffic volume. Also, if the Dial-in feature is used, one B channel will be dropped if necessary to allow the Dial-in call to be accepted.
  • Always use 2 B Channels. Both B channels are either open or closed. This provides better performance, but Dial-in connections can only be accepted if Internet access is not being used, and the ISDN phone line is idle.
Outgoing Call ID
Incoming Call ID
Use these to set the outgoing call MSN or SAD. MSN and SAD allow you to have multiple phone numbers.
Enter the require telephone numbers, selected from the phone numbers allocated to you by your phone company.
Advanced
B Channel Settings
These settings should only be changed if advised to do so by your phone company.
Use the settings advised by your phone company.

Options Screen

An example Options screen is shown below.

Administrator Password

Once a password is entered, it is required in order to change the device configuration. Passwords are case sensitive and can be up to 9 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.

When connecting, and prompted for the password, leave the "User Name" blank.

Remote Management

This feature allows you to manage the ISDN Internet Router via the Internet. If using this feature, it is strongly recommended to assign a password, as described above, to prevent unauthorized access.

The following settings are available.

Enable Remote Management
Enable to allow management via the Internet. If Disabled, this device will ignore management connection attempts from the WAN port.
Port Number
(Web Browser)
Enter a port number between 1024 and 65535. The default value is 8080 is recommended. This port number must be specified when you connect with your Web browser, as described below.
Note: The default port number for HTTP (Web) connections is port 80, but using port 80 here will prevent the use of a Web "Virtual Server" on your LAN. (See Chapter 7 - Internet Application - Virtual Servers for further details of Virtual Servers.)
Port Number
(Windows utility)
Enter a port number between 1024 and 65535. The default is 161. Change this number if desired. This port number must be specified when you connect (see below).
Note: The port number you select must NOT be used by any Virtual Server or Special Application. (See Chapter 7 - Internet Application for further details of Special Applications and Virtual Servers).

To connect using a Web Browser

  1. Ensure your Internet connection is established, and start your Web Browser.
  2. In the "Address" bar, enter "HTTP://" followed by the WAN IP Address of the ISDN Internet Router. If the Port number (Web Browser) value is not 80, the port number is also required. (After the IP Address, enter ":" followed by the port number.)
    e.g.

    HTTP://123.123.123.123:8080

    This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.
  3. If prompted for a username and password, leave the username blank, and enter the device password assigned to this ISDN Router.

To connect using the Windows "Manager" Utility

  1. Start the Windows Manager program.
  2. On the main screen, click the "Remote" button. A screen like the following will be displayed.

    Figure 10: Remote Management Dialog

  3. Enter the required data:
  4. Click the Connect button, and check the Connection Status area:
  5. On the main window, double-click the remote ISDN Router to configure it.

ICMP

Internet Control Message Protocol (ICMP) is used by devices such as routers, to report and acquire a wide range of network-related information.

The "ping" and "traceroute" programs also use ICMP.

To provide additional security, this setting is disabled by default. It should be enabled only if you need the ISDN Router to respond to requests from ping, traceroute and related programs.
