hold on..
you got a router at home, right??
if you do so, then install a "bridged" network. like that the vm will get an ip from your router!
NAT mode means that your pc pretends to be a router and assigns a virtual adresspool to the vms.
this is wrong ;)
just use a bridged adapter ;)
then start the vm, disable the network adapter (in the vm), enable it again, and type ipconfig in the commandline to see the ip adress.
put that ip adresss in the client's configs and you should be ready to go.
pm me if you still need help. i'm not here that often.
