Hi guys.
I have a question regarding subnetting and restricting access to certain parts of the network. Pretty much everything I know about networking (which isn't a great deal) is self learned through experimenting, so there are bound to be gaps or plain misunderstandings.
Let me explain the situation. I'd like to create two seperate networks, so that the computers on them can't communicate with eachother, but so they will be able to share the same modem, and also a printer. One half of the network will be handled by router 1, and the other by router 2 (there are more devices, but I left them out to keep the image simple).
Here's more or less how the network would be physically set up. The modem is downstairs and is conneted by wire to router 1 and router 2. My laptop (PC2) is connected wirelessly to router 2 (as well as a NAS/shared folder I plan to have, which isn't pictured). My sister's laptop (PC1) is connected wirelessly to router 1 and the intention here is that she does not have access to the NAS (or any other device connected to router 2, except the printer). Though I recognise as I've said that, that the printer would probably need a different IP address.
I also have an Xbox and PS3 that will be connected at the same physical location as the printer, and will be sharing media from an open shared folder on a PC at the same location as PC2.
I hope that by segregating the networks so all her traffic is restricted to within router 1 and mine within router 2, that it will kick her music stealing, network lagging tendencies into touch.
I was also thinking about the possibility of offering a wifi hotspot, but again it would need to be on it's own network, seperate from all the others to prevent intruders.
So what do you guys think? Is what I am aiming for possible, and if so could anyone give me a pointer as to the hostmasks? I gather for this kind of network it would be something like 255.255.252.0. Would you enter that same host mask for every device on the network, or if I'm wanting to restrict access, would I put a different hostmask on PC1 for example, compared to PC2?
I think maybe I'd have to change my addresses to 172.168.X.X also.
Many thanks
