Blocking access to internal LAN

Hi, We are planning on renting rooms to students and were thinking
about proposing wireless internet access. We currently have an in-house
wireless LAN that we would like to keep running the way it stands.
(Router: wireless Zyxsel, in-house network XP-home peer to peer.)

What would be the best approach for sharing the internet access and
router with the tenants while cutting off access to our LAN resources?
Would it be possible to create two indespendent (crypted) networks
sharing the same router? Is there a simpler workaround?

TIA for any advice, Mark

One easy way is to configure the XP SP2 Windows Firewall, if your running
XP, File & Print Sharing address scope to only allow access based on
specific IP addresses. That is what I do on my small home LAN so guest
wireless devices can access the LAN and the internet but not access shared
files/folders on my PCs.

Hi
Here is a solution that can cost less than $30 (or what ever is the price
that you have to pay for a second Router). http://www.ezlan.net/shield.html

Thank you very much to both of you for your answers.

I will look into the first possibility to save some pennies... The
second alternative is an interesting solution that I may use in the
future.
