CONFIGURATION OF SIMULTANEOUS INTERNET SHARING
Hopefully you already have a Local Area Network (LAN) connected even if only TWO computers are
If not go see our
local area network page
to see how we can help you with that!
Hopefully, you have or will have a broadband or high speed
connection to the internet, otherwise sharing (simultaneous) even two computers on a dial-up 56k internet
connection would be unusably slow.
WHAT WE RECOMMEND
We recommend a standalone dedicated firewall and router as it is
Linux based which is known to be more bullet proof and faster than
any Windows or MAC OS. The routing task needs the speed since you will be
moving incoming internet packets amongst computers. embedded high-speed
microprocessor 10/100Mbps ethernet LAN output (highest throughput)
We recommend that you are
using or will be using at least two computers that are sharing in LAN like
fashion, since one un-networked computer can be inexpesively protected by
firewall software on the one computer.
We recommend that you are
using or will be using a high speed, broadband connection cable, xDSL,
sattelite, other wireless to the internet, since dial-up 56k is too slow for
sharing though useful in backup situations. In all these situations we at
Accurate Computer can help you prepare.
The sharing (routing) and
firewall ()security) features are managed and set up by any computer with any
reason for recommending the standalone dedicated firewall and router is that it
will be easier to diagnos network problems which may be external or internal.
Also, a standalone dedicated device has reliable flash nonvolatile
flash memory for a holding configuration and avoids the failures of a
computer even dedicated computer doing the same job having many external
peripherals attached like floppy, hard drives, keyboards, mice, or monitors
which can fail and stop the routing-sharing-firewalling.

Your Broadband Internet Provider: Connect your modem to
Your provider provides a broadband connection by a Cable, DSL, or Satellite device called a modem,
router, bridge or receiver. It will have an (usually) ethernet (sometimes
USB) connection to your single computer. This is all you need to order
from your broadband high speed internet provider. You do not need to order
more than one IP address or connection to the internet. See below.
As far as your Broadband high speed internet provider is
concerned you are connecting only to your single computer. If you already have
some local area network designate one of the computers as the one to receive and
get installed to the service provider. Perferably choose the one closest to the connection if you
know where that is.
What we do: Connect your modem to router
Later, your modem, router, bridge or receiver are then connected
to your firewall-router Internet Sharing device instead of your single
We then add the Internet Sharing device Firewall-Router
which we connect to the Hub.
This is were the internet ends and local area
network begins ie. firewall.
During installation we will need information on the IP
address (dynamic or static) of your single computer as it was connected to your broadband
high speed internet provider and in some cases a
gateway address or PPOE login information for your single computer.
Your broadband provider:
You do not need to order more than one IP
address or connection to the internet. The firewall-router or internet sharing
device will provide what is know IP NAT. This is a translation
between all your computers different addresses to a single address.
What we do:
We connect the router-firewall to your LAN or setup your LAN if you have
Then each one of your computers MUST be
setup and configured for low level and even some high level features of security
and sharing both on the Internet and LAN. Check out the network features page.
AT this point your Internet-Sharing firewall-router device must be setup
and configured for most if not all the features or needs you thought of
