floppyfw is a router with the advanced firewall-capabilities in Linux that fits on one single floppy disc.
Features:
* Access lists, IP-masquerading (Network Address Translation), connection tracked packet filtering and (quite) advanced routing. Package for traffic shaping is also available.
* Requires only a 386sx or better with two network interface cards, a 1.44MB floppy drive and 12MByte of RAM (for less than 12M, use the 1.0 series, which will stay maintained).
* Very simple packaging system. Is used for editors, PPP, VPN, traffic shaping and whatever comes up.
* Logging through klogd/syslogd, both local and remote.
* Serial support for console over serial port.
* DHCP server and DNS cache for internal networks.
