whereas iptables -F without 'name' will 'flush all rules in chain'.

In earlier versions of iptables, code such as

So, referring to: home router, I should,
instead of relying on the (at the very top) iptables -F, use, at the very end (before the rc-update
command group), something like this:

iptables -X my-own-foo
iptables -N my-own-foo
.. other rules ..

instead of, just:
iptables -N my-own-foo

maybe?

[Edit] Yes, that works. Thanks
