Re-save iptables rules with iptables-persistent

When installing iptables-persistent with apt

# apt install iptables-persistent

the shell takes me into a wizard which asks me if I want to save the current IPv4 and IPv6 rules

So then, later, when I’ve made some more changes to my iptables ruleset, instead of manually putting the rulesets into files with iptables-save and ip6tables-save, I can re-run the wizard iptables-persistent which does it all for me:

# dpkg-reconfigure iptables-persistent
