If you want to protect your staff RCs, then create a proxy server on your High speed cable or faster connection.
Make sure you need a username and password to use the Proxy, or else anyone would be able to use them.
Once you have a proxy address working, have your staff insert the information in their browser properties. (Such as MSIE5&6). Then set the IP range for your proxy for each member. This makes it so any outside intruder cannot connect due to an incorrect IP address.
