I think y'all misunderstood me - I just want to say "turn off", run my
script to test it, and turn it back on.

However, I found out something: iptables -L gives the rules,
also....*only* for IPv4; ip6tables -L does the same for only 6. And it
does look as though by shutting down ip6tables, it did turn them off -
ip6tables shows on 8 lines, which are all aCCEPT. I'd been looking at the
o/p of iptalbes-save, and ip6tables-save.

Thanks, though.
