Congratulations on the purchase of your new
ISDN Internet Router.
The ISDN Internet Router will allow
multiple users on the LAN to gain shared Internet access. Users can share the ISDN
connection and the Internet user account.

The ISDN Internet Router provides a
low-cost method of giving users of your network access to the vast resources available on
the Internet. Once the ISDN Internet Router is installed and configured, the Internet is
just a click away.
The ISDN Internet Router is able to use
your ISDN link to connect to your ISP (Internet Service Provider), providing the required
log-in information.
Alternatively, you can use the ISDN
Internet Router to provide a seamless, automatic connection to another LAN, provided a
matching device is installed on the other LAN.
The ISDN 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.
A DHCP (Dynamic Host Configuration Protocol) Server provides a
dynamic IP address to PCs and other LAN devices upon request.
The ISDN Internet Router can act as a DHCP Server.
- 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.
- 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 special-purpose 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 ISDN Internet Router supports Outgoing call ID for both MSN (Multiple Subscriber
Numbering) and SAD (Sub Address).
Configuration & Management
- Easy Setup.
Connect to the ISDN Internet Router with your WEB browser from anywhere on the LAN for
configuration.
- Remote Management.
The ISDN Internet Router can be managed from a workstation anywhere on the LAN, using a
WEB browser.
- Remote Monitoring.
Using the Web-based interface, Internet access via the ISND 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 ISDN
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.
For internal users, the ISDN 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 ISDN 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. |
