Project description

Dynamically save and restore iptables rules for some chain(s)


When there’s an iptables service restart, all of the docker rules gets wiped out. This script was written to dynamically save and restore iptables rules pertaining to some chain(s) and make them persist.


  • iptables (Must have the commands iptables-save and iptables-restore commands available)


pip install iptables-dynamic


iptables-dynamic --chains DOCKER SOME-OTHER-CHAIN --save

which would save them at /etc/iptables/rules.v4

One can restore those rules by

iptables-dynamic --restore

One may also use ip6tables-dynamic for IPv6.
