Good to know that there is a replacement for {ip,ip6,arp,eb}tables,
I'll look into this once I have found some time.
However, I was just wondering what the difference is between your
script and iptables-persistent. Wouldn't both restore the iptables
configuration form a single file? Or is there some other benefit by
choosing one over the other (besides a personal preference)?
Best,
Tim
