Thanks for your patch.
Rewrite is ok, I'd just also drop dots from messages.

Also redirection to tst_iptables.out in cleanup() is pointless,
maybe we could just change:

cleanup()
{
	if lsmod | grep -q "ip_tables"; then
		NFRUN -F -t filter > /dev/null 2>&1
		NFRUN -F -t nat > /dev/null 2>&1
		NFRUN -F -t mangle > /dev/null 2>&1
		rmmod -v ipt_limit ipt_multiport ipt_LOG ipt_REJECT \
			 iptable_mangle iptable_nat ip_conntrack \
			 iptable_filter ip_tables nf_nat_ipv4 nf_nat \
			 nf_log_ipv4 nf_log_common nf_reject_ipv4 \
			 nf_conntrack_ipv4 nf_defrag_ipv4 nf_conntrack \
			 > /dev/null 2>&1
	fi
}

For further work on iptables tests: I wonder if nc is more commonly installed in
distros than telnet (if yes, I'd be for using it).

But for nft01.sh I got error:

nft01 1 TINFO: INIT: Flushing all rules.

Tested on openSUSE Tumbleweed (5.3.8-1-default, nftables v0.9.2 (Scram),
iptables v1.8.3 (legacy)) and Debian unstable (5.2.0-rc3+, nftables v0.9.0 (Fearless Fosdick), iptables v1.8.2 (nf_tables)). Am I missing something, have wrong version?

Kind regards,
Petr
