Access a computer on my network

Electronics, Music and Technology Creating a Private + Guest WiFi Access Point (DD-WRT) Recently I was asked to configure a WiFi access point for a small business, who needed to have both a private internal network, and a public guest network. There are many privacy concerns when having guests share your network. Specifically, it is desirable to: Disallow access to any computers on the private network Prevent network abuse (such as P2P file sharing) Secure the access point itself from tampering or unauthorized access Of course, all this needs to be done without impacting the desired service: Internet access.
