I am on a University network where I live and I would like to create a small, but private network that I can use to connect three computers: 2macbooks and one linux(redhat) box and an ip printer to all be on the same local/private network. I want all three computers to be able to print and share files, but I want this network to be private to the outside world but have the ability to connect to the internet. My inet is the same as my broadcast address so I'm not sure if I am on an internal network, but I can't use dhcp on my DI-624 router to hand out local IP's. I can use it as a switch, but can I create some sort of network with my router to one that only I can see? Any help would be great. I know school networks are a tough subject, but any suggestions would be great.
