OpenBSD Live-CD Firewall 3.8.1

OpenBSD Live-CD Firewall is an OpenBSD-based pf (packet filter) firewall, with DNS, squid, NAT, and a DHCP server (dnsmasq) for internal clients preconfigured. Settings and log files can be saved to a USB device.
Saved settings will be restored at the next reboot. Additional security related software is available on the CD (arpwatch, honeyd, ntop, portsentry, etc.)
Main features:
- runs without modifying the hard-drive
- external interface will be configured via DHCP - should work with a Cable Modem connection
- DHCP service for internal LAN
- caching DNS
- Squid Proxy
- NAT (masquerading)
- save your configuration and passwords to an USB mass-storage device (usb-pen drive) [ /backup/etc2usb ]
- If the USB device is connected at boot time these settings will be used.
- save all log files to an USB mass-storage device for future analysis [ /etc/log2usb ]
Enhancements:
- The Squid proxy server works now in transparent mode without further configuration.
