:confused: Someone out there must know why there are "Dual RJ-45 Lan ports" on some motherboards? I'm sure someone out there knows....could you please tell me? :o

Hi,

Motherboards with two LAN ports are used if you want to assemble a small network (e.g. share your internet connection, files and printer with another computer) without buying a router -- so your computer will work as a router. To do that, connect one of the ports to the broadband modem and the other to the LAN port found on the second computer thru a cross-over cable (all you will need is this "special" cable).

It can also be used if you want to setup the PC as a hardware firewall or a proxy server on a network, i.e. the computer will be between the internet connection and the other computers.

Cheers,
Gabriel.

Thank you.
