        <pre>I recently upgraded a Debian 9.11 system to Debian 10.3.

The old system had ip6tables v1.6.0 and I used iptables-persist
to load the following simple configuration for IPv6:

:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -j REJECT --reject-with icmp6-port-unreachable
-A FORWARD -j REJECT --reject-with icmp6-port-unreachable
-A OUTPUT -j ACCEPT
COMMIT

which worked perfectly fine so far. After the upgrade, I had to
change "icmp" to "icmpv6" or else the system would block icmpv6
traffic.

The upgraded system now has iptables-nft, version v1.8.2 (nf_tables).</pre>
