I use awall on Alpine, and I am confused as to the origin of two firewall
rules, both in the input and output chain. Here they are, as displayed by
"ip6tables -L -v":
Chain INPUT (policy DROP 0 packets, 0 bytes)
[...]
3 168 ACCEPT ipv6-icmp -- any any anywhere anywhere
96 6082 logreject-1 all -- any any anywhere anywhere
Chain OUTPUT (policy DROP 0 packets, 0 bytes)
[...]
16 1312 ACCEPT ipv6-icmp -- any any anywhere anywhere
21 2556 logreject-0 all -- any any anywhere anywhere
I want to restrict ICMPv6 (using the policy of drop), but the first of
the rules listed for each chain seems to undermine that. Grepping around
my Alpine filesystem has not indicated where these rules come from. I
don't think they result from the configuration I have in /etc/awall.
