It doesn't appear possible to configure a firewall rule to allow ICMPv6, or am I missing something? Following is a first attempt using icmpv6 and then when attempting icmp.
gcloud compute firewall-rules create test-ping-ipv6 \
--network <network name> \
--priority 1000 \
--direction ingress \
--action allow \
--source-ranges <IPv6 CIDR> \
--rules icmpv6
Creating firewall...failed.
ERROR: (gcloud.compute.firewall-rules.create) Could not fetch resource:
- Invalid value for field 'resource.allowed[0].IPProtocol': 'icmpv6'. Must be one of ["ah", "all", "esp", "icmp", "ipip", "sctp", "tcp", "udp"] or an IP protocol number between 0 and 255.
