ferm is a frontend for iptables, providing a way to write manageable rulesets without sacrificing flexibility. To use ferm, you need know how to write iptables rules.
ferm is dead upstream and kept alive inside Debian to aid transition. The package is maintained on [[https://salsa.debian.org/debian/ferm|Salsa in the Debian/ferm project].
See README.Debian inside the package for a more detailed explanation.
ferm has reported incompatibilies with the nftables version of iptables. This page exists to document those incompatibilities and workaround. If you encounter weirdness with ferm 2.7-5+exp1 or later, please:
- document the issue
- give a reproducer
- document whether it disappears when switching back to iptables-legacy
- document possible workarounds
Thank you for helping.
