Home Network Layout/Advice

post #1 of 6
Thread Starter 
Hi,

I was thinking about improving my home's Network. Currently I have 3 computers all on the same Windows 7 homegroup on one router. I want to add a Win XP computer to this however I don't want it to have any sort of internet access.

What I'm planning to do is keep the 3 computers in the Windows 7 Homegroup but along with a sort of internal network which doesn't have access to the internet but does have access to the Files on any one of the windows 7 Computers and vice versa. This should also be compatible with different versions of the MS Windows; XP, Vista, etc. It is also important for this to be done wireless.

so for example Computer A, a Windows 7 Homegroup member, is able to connect to the internet. Computer B, a Windows XP, is able to view and share files wirelessly with Computer A. However Computer B does not have the ability to connect to the internet.

Does anyone have any insight or a better way of doing what I described above ? Basically want Specific computers to be able to access the internet through the router and have specific computers to only have the ability to share files but must be shared wireless.

I was thinking about using an ad-hoc sort of setup. But just want to see if there are better alternatives.

I've never cut off a computer from a network before, but this might work.

- Connect WinXP to network.
- Assign a static IP to WinXP
- Block ALL Services to WinXP's IP

If that doesn't work, then setup multiple blocks for different type of services to the WinXP machine. I think this will cut the machine from the internet without hampering the interaction with the network.

This would be better suited for either a firewall or VLANs where you can specify which networks have a route to the WAN but still access other internal networks.

I imagine you could remove the default route on the XP machine and have your users use non-admin accounts. Then they could not re-add this route but still have access to internal resources. I'm not sure how persistently this would be removed though.

I'd use VLANs, assuming you can.

another for VLANs
post #6 of 6
The use of VLANs is a must however what everyone has failed to mention is how the traffic will be blocked. Beers pointed out that a firewall would be the best solution for this, in which I would agree. Yes it could be done with a routers ACL, however deeper packet inspection may be necessary and it depends on the OP's requirements.
