Hopefully you already have a Local Area Network (LAN) connected even if only TWO computers are connected TOGETHER. 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.

  • 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 browser
  • Another 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.
  • TFTP for firmware upgrade over the internt

  • Share your broadband DSL/CABLE/Sattelite connection using only one IP address NAT.

  • WAN DHCP client for WAN port (even if your BB ISP uses dynamic IP
  • IP multicast IP/TV
  • DHCP for LAN port assigns all the fake IP addresses to the computers on network having DHCP clients Win, MAC Linux etc.
  • NAT network address translation ISP sees only one computer
  • Natural firewall
  • IP filtering firewall
  • virtual server firewall
  • Visible computer firewall setting
  • Menu driven telnet option

  • Your Broadband Internet Provider: Connect your modem to aomputer

    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 computer. 
  • 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 not already.
  • 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 above.
