File Sharing - How to Block Guests ?
Some advice needed please.
We have a small network which includes 3 PCs (Desktop Win 7 Ultimate x 64, Laptop Win 7 Ultimate x 86, and a Laptop Win XP Professional). These 3 PCs file share on the network (in all directions), the Laptops using Wi-Fi. The router is the latest Orange Livebox (French version), and we use this as our package includes free phone calls using the Livebox connection.
We run a small holiday rental which includes access to the internet for the guests using Wi-Fi.
What I would like to know is can the guests also see the files on our network PCs?
If they can, is there a way to prevent this? (Perhaps configuring our firewalls - Eset Smart Security on all 3 PCs).
I hope that I have explained clearly, and any advice would be much appreciated.
TIA,
Paul.

That is not very secure at all. I would say that the likelihood of guests being able to see your files (and, conversely, you being able to see theirs) is quite high. You should really be using separate networks in a business environment, in order to keep the staff side private and apart from your guests and other users. If you have confidential data (and I suspect that you do), then it is very important that you take steps in order to protect it. What you can do, if you don't have a guest facility on your router, is to attach another router to your main one via one of the Ethernet connections. This new router will then become the wireless connection for your guests. You can now make the primary router secure for the staff. On this router, enable SSID (don't broadcast it), WPA2/PSK and MAC filtering to ensure that only authorised devices can connect.
