We have four actual hosts here;
My Macbook running Linux which will be home to a few assorted Virtual machines.
My MacMini which is will be my Media Center and host to an Active Directory based network, it's mainly a windows lab but has a linux and mac host to experiment with connecting them to windows based networks.
My Desktop PC will be host to my Attack Lab, comprising of vulnerable hosts, a firewall, one subnet posing as an internal network and one posing as an external network.
And finaly an EEEPC Netbook with a broken keyboard will act as a Gateway.
I have an internet connection provided via wired Ethernet in my building. I share the LAN with my neighbors but I connect to the internet via a router that uses NAT filtering. To connect you must log in via a webpage after which you can use only that one device to go online, syncing a phone for example means loggin off via the last device used and logging in via the phone. In short it's a pain.
I could get around this using ARP spoofing but I wan't to be a nice neighbour and do this properly. So here's the plan. The EEEPC is going to act as a NAT bridging my network to the buildings network, my buildings router will then function as a second NAT bridging the buildings LAN to the Internet. If possible I'd love the EEEPC to log in
