Brief Description

Floppy Firewall is a router with the advanced firewall-capabilities in Linux that fits on one single floppy disc.


  • 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 and no FPU, 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. (now this is looking even more like LRP (may it rest in peace) but floppyfw is not a fork.)
  • Logging through klogd/syslogd, both local and remote.
  • Serial support for console over serial port.
  • DHCP server and DNS cache for internal networks.
  • SSH-server for remote administration.
  • VoIP traffic shaping for preventing IP phones to be affected by downloads/uploads.
  • It will get more features, but only if it is possible to cram it into the one, single diskette. More than one floppy is bloatware..
