Allow IPv6 pings to local devices?
The debug.htm page of my RBR50 provides an option Allow external IPv6 hosts ping internal IPv6 hosts This seems to default to enabled. I turn it off when I happen to see it, but it comes back on...
Given that IPv6 requires fully-functioning ICMP in order to work correctly, I'd say it presents no risk whatsoever (and I'm quite mystified as to why it's even selectable).
"Protection by ping block" went out in the early 2000s. It's trivial to detect the presence of machines by (many) other means.
