A few months ago I posted a message about a new user joining in on our wireless network, and the discussion centred around ways in which that user could use the network to access the internet but not be able to access other machines on the network.
The subject has come up again, and without expecting a complete re-analysis of the problem, I wonder whether what I want to achieve can be achieved by using a custom subnet mask.
First question is, if I use a custom SNM in order to create 2 subnets, can either subnet access files on hosts on the other subnet?
Second, how are physical segments actually defined? I suspect I cannot do this with 1 router, since everything directly connected to that router (wired or wireless) is as I understand it on a single physical segment.
Let's say I have two routers, is it possible to have one subnet which covers any machine directly connected to that router (say, wired), and have a second cable going out to a second router, and anything connected to that second router (wired or wireless) on a second subnet? Or is that really everything being connected to the first router (directly or indirectly) therefore only one physical segment?
If not is there any other way to use two routers to create two subnets (assuming it achieves the security I'm looking for by denying each subnet access to files on the other)?
When all is said and done, is it possible to just use Sharing and Security feature in XP to determine who can see what and access what across the network, or is this flawed in some way?
