Isolating computers on a LAN from each other - A special kind of switch
Hello All,
I have an ADSL modem with just a single connection coming outof it, which goes into a simple simple hub to which I've connected several computers. Currently I want to install another computer on which I should be able to do *anything* with it in regard to downloading stuff from the web, which means its pretty open to catching some sort of disease .... For this reason I need it to be seperated from my other computers (only be able talk to the internet, not to any of the other computers I have). I thought of a special kind of switch, one with a single output (to the model) and two or more inputs (from the computers). The data coming from the inputs will only be routed to the output, *not* to any of the other inputs. Ofcourse, any data coming in from the modem for one of the computers will be routed to it (and only it). My question : does some sort of device like it exist (for the consumer-market) ? I've taken a look at NetGear and LinkSys, but can't seem to create a search-query to return anything worthwhile. If anyone knows another solution (*not* involving setting up a seperate computer) I would allso like to hear about it. Regards, Rudy Wieser |

Isolating computers on a LAN from each other - A special kind of switch
Hi
First you should know that your DSL Modem is probably a combo Modem/Router. This page depicts the principle of one good option, http://www.ezlan.net/shield.html Disconnect the computer from the Hub and leave on the hub only the Internet Computer. Plug to the hub a regular Wireless Router. Connect the rest of the computers (wire, or and Wireless to the Wireless Router). As a result, all the computers would be able to surf the Internet. The computer after the second Router would be able (if you wish) to pickup files from the Internet only computer. The Internet only computer would not be able to access the computers (wire or wireless behind the second Router). "R.Wieser" wrote in message ...

Hello Jack,

The computer after the second Router would be able (if you wish) to pickup files from the Internet only computer I've been thinking about a solution like that, but it would mean that I than have *two* NATs and firewalls to manage for the "safe" computers. And thats something I want to avoid. The double NAT would not be much (if any) of a problem (I think), but a double firewall seems often to lead to undesirable results ... Thanks for the suggestion though. Regards, Rudy Wieser -- Origional message Jack-MVP schreef in berichtnieuws ... Hi First you should know that your DSL Modem is probably a combo Modem/Router.

The configuration he describes does not have the issues that concern you. In addition, the potential problems with two firewalls are when you have two software firewalls running on the same machine, not firewalls running on two different machines (consider that the most common recommendation is to run a *software* firewall on your PC notwithstanding that it is behind the *firmware* firewall running on your router. -- Lem -- MS-MVP Apollo 11 - 40 years ago this month: http://www.nasa.gov/mission_pages/ap...0th/index.html |

Hello Lem
Thanks for the warning, I'll re-read what he suggested. As for two software firewalls on a single machine, I must say I did not even consider that.
