Using iptables-persistent on Debian
Note: In use on vrijdagmiddagborrel.
It's basically a set of iptables plugins for netfilter-persistent, which itself is a loader for different netfilter configuration. Once installed, it will take care of restoring rules at boot time, and through a small helper, can be used to reload/update/save rules on the fly.
Installation and config
- Installation:
apt install iptables-persistent netfilter-persistent
- Add/change iptables rules located at
/etc/iptables/rules.v4and/etc/iptables/rules.v6
Usage
- Apply new rules after changes made to
rules.v*files and check result
netfilter-persistent reload iptables -L
iptables oneliners
- list all rules from all chains
iptables -L
