Thank you all. So now I have to buy a lan card for the first PC (because in the schematic I made, the PC with internet has 2 Lan cables connected but only one LAn port). I found a cheap Lan card with only 5 Euro plus some for shipping. And the card I will buy has only 100 speed, enough I think for the internet. And I will use the integrated Lan port with the 1000 speed in order to have a 1000 speed connection with all other PC's. - No problem using a 100 card in a pc ? No conflicting with the integrated 1000 Lan ?

So..in the picture below you can see the schematic I made. The internet enters in the first PC thru the DSL box , and I wanna connect the internet PC with the other PC's with a giga lan speed. For that I think I will need a second Lan card because the internet PC only has one lan port. Next I use the Dlink 8 ports Switch. But I don't want the internet go from the internet PC thru the Dlink and to the other PC's. Because I don't wanna put firewall and stuff on the other PC's. But maybe with this setup, the internet will just naturally stop at the first PC ? - And also this is the only possible setup ? Thanks.
