PacketProtector is a Linux distribution for wireless routers, built on top of OpenWrt. The goal of this project is to transform the router into a unified threat management device. Here's what you get- a stateful firewall (iptables), WPA/WPA2 Enterprise wireless (802.1X and PEAP with FreeRADIUS), intrusion prevention (Snort-inline), remote access VPN (OpenVPN), content filtering/parental controls (DansGuardian), web antivirus (DG + ClamAV), anti-phishing (OpenDNS), automatic updates (for Snort and ClamAV), a local certificate authority (OpenSSL), secure management interfaces (SSH and HTTPS), advanced firewall scripts for blocking IM and P2P apps, IP spoofing prevention (Linux rp_filter), basic protocol anomaly detection (ipt_unclean), Each of these services is automatically bootstrapped and configured with sensible defaults. A secure web interface makes common configuration tasks as simple as a point and click. All you need is a Linksys WRTSL54GS or ASUS WL-500g (Deluxe or Premium) router, and a USB 2.0 drive with 100MB of free space.....(free).....
