DESCRIPTION¶
netfilter-persistent uses a set of plugins to load, flush and save netfilter rules at boot and halt time. Plugins can be written in any suitable language and stored in /usr/share/netfilter-persistent/plugins.dOPTIONS¶
- start
- Calls all plugins with the start argument, causing them to load their rules into netfilter.
- stop
- If the configuration FLUSH_ON_STOP is enabled, calls all plugins with the flush argument, causing them to remove their rules from netfilter. Otherwise, emits a warning only.
- flush
- Calls all plugins with the flush argument, causing them to remove their rules from netfilter.
- save
- Calls all plugins with the save argument, causing them to save the currently-loaded rules to persistent storage.
PLUGINS¶
Plugins can be written in any language and are merely executed by netfilter-persistent with a single argument. All plugins are stored in /usr/share/netfilter-persistent/plugins.dPlugins must implement the start flush and
save arguments and must not rely on additional arguments for other
functionality.
Plugins must return 0 on success and any other code on failure.
Plugins are free to use and extend the configuration in /etc/default/netfilter-persistent and to implement their own configuration files.
