I have a home LAN with a few machines, one of them running Windows 2000 Advanced Server and I also have a couple friends with setups like mine. We each are connected to the internet via broadband with a static IP. Is there a way we can network each of our LANS together through the internet? I would like it where each computer on each lan is accessbale through Network Places. Each LAN is also behind a firewall, so what ports would need to be opened for this to work. Any help is greatly appreciated.
