Michelangelo Gateway

INTRODUCTION
Overview●
Features●
Overview
Michelangelo Gateway will allow multiple users on the LAN to gain shared Internet access. Users can share the ISDN connection and the Internet
user account.
Figure 1: Office to Internet
Michelangelo Gateway provides a low-cost method of giving users of your network access to the vast resources available on the Internet. Once
Michelangelo Gateway is installed and configured, the Internet is just a click away.
Michelangelo Gateway is able to use your existing xDSL/ADSL/Cable modem link to connect to your ISP (Internet Service Provider) using your
Single User Account
Features
Michelangelo Gateway incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use.
LAN Features
Michelangelo Gateway

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.
Michelangelo Gateway can act as a DHCP Server.
●
Multi Segment LAN Support.
If you have a Router, PCs on other LAN segments can use Michelangelo Gateway to access the Internet. A static routing table is provided to
support multiple routers if needed.
●
WAN Features
10BaseT Wan port
This port is for connecting the external xDSL or Cable modem (must provide Ethernet connection).
●
PPPoE Support.
Connect to your ISP using PPPoE (PPP over Ethernet), if your ISP uses this method.
●
Direct Connection to ISP
Connect to your ISP by using Direct connection method if required.
●
Internet Access Features
Shared Internet Account.
All users on the LAN (max 253) can share the same Single USer Internet Account.
●
Advanced Internet Features
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.
●
*Netmeeting may not be supported. For more details see infos on Online Help at www.digicom.it.
Configuration & Management
Easy Setup.
Connect to Michelangelo Gateway with your WEB browser from anywhere on the LAN for configuration.
●
Remote Management.
Michelangelo Gateway can be managed from a workstation anywhere on the LAN, using a WEB browser.
●
Security Features
Configuration Data.
Optional password protection is provided to prevent unauthorized users from modifying the configuration.
●
Access List
The LAN Administrator can limit Internet and E-Mail access by individual workstations.
●
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.
●
LAN Data Protection
All users on the LAN share a single external IP address. From the external viewpoint, there is no
network, only a single device.
For external requests, any attempt to connect to local resources are blocked. The router will not
"reverse translate" from a global IP address to a local IP address.

SETUP
Overview●
Other Setup●
Overview
Other setup is required only for the following situations:
Your LAN has a Router or an existing DHCP Server.
● The default IP Address range is not suitable for your situation.● You wish to use a password to protect the configuration data.● You wish to take advantage of the advanced features of Michelangelo Gateway.●
Other Setup
Except in the following circumstances, no other configuration is required.
If using an existing DHCP Server:
Configure it to provide Michelangelo Gateway's IP Address as the Default Gateway.
● The DHCP Server in Michelangelo Gateway should be disabled. This setting is on the LAN Tab .●
Device'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
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 Michelangelo
Gateway correctly. See Routing for details.

Routing
Overview●
Routing Example●
Routing Table Entries●
Overview
While Michelangelo Gateway includes a standard routing table, this 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 Michelangelo Gateway correctly, as described in the
following sections.
Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to Michelangelo Gateway, so that they can be forwarded to the Internet.
To achieve this, the Routers must be configured to use Michelangelo Gateway as the Default Route or Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as Michelangelo Gateway. This router requires that the Default Route is
Michelangelo Gateway itself. Typically, routers have a special entry for the Default Route. It should be configured as follows.
Destination IP Address Normally 0.0.0.0, but check your router documentation.
Network Mask Normally 0.0.0.0, but check your router documentation.
Gateway IP Address The IP Address of Michelangelo Gateway.
Metric 1
Other Routers
Other routers must use Michelangelo Gateway's Local Router as the Default Route. The entries will be the same as Michelangelo Gateway's local
router, with the exception of the Gateway IP Address.
For a router with a direct connection to Michelangelo Gateway's local Router, the Gateway IP Address is the address of Michelangelo
Gateway's local router.
●
For routers which must forward packets to another router before reaching Michelangelo Gateway's local router, the Gateway IP Address is
the address of the intermediate router.
●
Routing Example
Michelangelo Gateway

Figure 1: Routing Example
For the LAN shown above, with 2 routers and 2 LAN segments, the required entries would be as follows.
