Vlan

ref to Overview 18/1/11

Realy. I dont know what i want to do about the Vlan.
I have tryed to look a the 3. semester reports about the Vlan and tryed some of the commands that cood have workt.
What i think i want is i want to seperate 2 lan's so we can have a lan where all the PC's and printers are and 1 where externals machines are and the can cumunicate.

Back of the Router
Layer 1

On layer 2 i need to get the server and the Windows PC on 1 Lan and  the external PC on Lan 2 that got another IP than the Lan 1 but they can still talk togeather.

Not know if the is Info is OK but i cant figure out more els i need to read a bit more about this subjekt
