The Public IP ZoneCD has been created to help implement safe, free, wifi hotspots. NoCat dynamic firewall rules are used for user access and authentication. A transparent proxy sends all "Public" requests from NoCat through a content filter (Dansguardian) to block porn, hacker sites, extreme violence, illegal drugs, and other obscene and explicit Web sites. The content filter also blocks files extensions to protect your network from viruses, and restricts file sizes to save bandwidth.
