reload iptables w/ initial settings

[Tzuriel]

I was working with iptables and have made some mistakes to where I'd like to flush everything and reload with the configuration that comes with Gentoo, but not sure how.

Thoughts?

By default, the location where rules are saved is IPTABLES_SAVE=/var/lib/iptables/rules-save as defined in /etc/conf.d/iptables.

Stop iptables, delete or move the "rules-save" file, and I believe you'll have the default rules the next time iptables is started (at least with openrc as /etc/init.d/iptables sets up some defaults).

If you don't specifically need iptables, you might instead consider using its successor, nftables.

If you haven't yet restarted the iptables service you should still have a copy of all your previous rules in the file mentioned by pjp and can restore them using the script iptables-restore:

Code: Select all

iptables-restore /var/lib/iptables/rules-save
