This Chapter details other configuration possibilities and options which are not normally required.
A DHCP (Dynamic Host Configuration Protocol) Server provides an IP address and related data to a DHCP Client (PC or device) upon request.
If using an existing DHCP Server, rather than the DHCP Server in the ISDN Internet Router, the following changes are required:
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. |
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.
The ISDN tab on the Manager program is shown below.
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:
|
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.
|
An example Options screen is shown below.
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. |
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).

HTTP://123.123.123.123:8080
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.
