Hello. I'm having trouble setting up a network to work how I want and I'm not exactly sure if it's 100% possible. Here's what exactly I want to do:
I'm at a university and we are allowed to use only one Ethernet port for any networking. Whatever we do with that Ethernet port is completely up to us. The problem here is that I have multiple devices that I want to connect to this port and to do so I have a WRT600Nv1 router (running the latest DD-WRT Mega Build). This works fine for connecting the devices to the internet but I would also like to have some sort of private "home" network on the router itself where my devices can connect freely to one another without having to worry about other people on the school network accessing my shared files. Is it possible to run some configuration where my computers would have a form of "virtual LAN" between one another that is separate from a "public LAN" where each device would separately have access to the internet through the school's network? If so, would someone mind explaining to me how I would manage to set up this sort of configuration?
Would it be better to just use password protected methods of sharing files between my computers on a public LAN instead?
Any help or suggestions are welcome! Thanks.
