netshun auto-heals the firewall

netshun detects its nftables state was wiped and rebuilds every ban automatically within seconds.

Your firewall got wiped. netshun didn’t care.

When nftables rules get flushed — a script, a misconfigured service, anything — every banned attacker gets straight back in. Normally you’d have to recreate the rules by hand.

netshun keeps its ban list inside nftables and watches for changes. The banned set has the attackers in it. Flush the whole ruleset and list it immediately — completely empty. Wait six seconds. netshun notices and rebuilds every ban on its own. No manual step.

The firewall heals itself. Your blocked attackers stay blocked even if the ruleset gets wiped under you.
