We have a conference room which we hire out to the general public, and as part of the facility we'd like to offer WiFi access. We have a firewall to prevent incoming threats from the internet, and each of our workstations has Kaspersky Antivirus on them. As we have no control over what is on the laptops belonging to delegates using the conference room, how can I protect my network from any threats on delegates computers. We're running windows server 2003, and all our workstations have windows XP professional installed. The Wifi network will be WPA encrypted to prevent unauthorised use. We're a charity so have a limited budget.

Yours - Antony

Is the conference room WiFi connection to be used only for access to the Internet and not allow any access to the computers and any shared printers?

Do you currently have your existing network hardware plugged into a LAN port on a broadband modem

If both answers are, "Yes," a fairly safe and inexpensive method might be to add a second wireless router that also has wired LAN ports. The new router would go between the modem and the current LAN hardware. The new wireless router would have its own simple WPA encryption key to keep a neighbor or someone in your parking lot from stealing internet bandwidth but fairly easy for an authorized guest user to type in when establishing a connection. The new router would need to be set up to do port forwarding to the existing hardware or put the existing hardware in a DMZ.

Dear Chuck,

Thanks for your reply.

The answer to your first question is yes, the wireless is just for internet access. But to the second is no, our router and modem are all one device, a Fritz Box 7170 which is also a VOIP router, the conference room wouldn;t require VOIP.

Yours - Antony

How are you connected to the Internet? You can accomplish this protection by using two routers daisy-chained, the one connected directly to the ISP connection services the conference room, and the second router is used to serve your network. It provides a NAT layer to block any activity in the conference room from affecting your network activity.
