Hi all,

Have a LinkSys WIFI router with integradted DSL modem and 4 port ethernet. Currently have two computers hardwired, and want to add one or two more via WIFI.

Question - is there any way that I can give one of the wireless computers internet access but no access at all to the other machines on the network? In this case, it would be to allow a student who lives in a rented studio in our house to have internet access via my connection without having to pay for his own DSL line, but I would not want him accessing my files. For the others, I need file exchange.

I can think of one way with my limited network knowledge - limit the areas of shared resources and make all password protected - which is a bit of a pain. Any way to set up firewalls so that I could, say, exclude the student's computer from all other network access while leaving the other computers relatively free to communicate and share?

TIA, --Mitch



You could use MAC filtering and/or static IPAs to "prevent" the student from
accidentally stumbling into your shared resources, but it would still be easy
for the student to override your settings on said student's PC by MAC and
IPA cloning.

For real protection, you need a second wireless router, with different WPA keys
and a different IP subnet, such as:

DSL<==>Router1<==>Router2<AllOfYourPCsAttachHere>
\ +--<StudentPCsAttachHere>

All in all, you may find it easier to keep the single router you have and
migrate all of your PCs to XP PRO (if they aren't), disable simple protection,
and use XP PRO's credential checking to bar the student.

Oops - my mailer reformatted my message behind my back. As I drew the
picture (in ASCII art form), it showed the StudentPCs attached to
Router1, with all of YourPCs attached to Router2.

Sorry about that.
