            Bug ID: 1412
           Summary: ip6tables-nft not accepting "icmp" as shorthand
for
                    "icmpv6"
           Product: nftables
           Version: unspecified
          Hardware: x86_64
                OS: Debian GNU/Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: iptables over nftable
          Assignee: pablo at netfilter.org
          Reporter: goliath at infraroot.at

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).
