It's very dangerous proposal when we start considering everything 0
value which isn't value to ourselves cur
Hi Eric,
in addition to RFC 4980 mentioned in another post you might consider the
following sources as a starting point:
https://insinuator.net/2015/12/developing-an-enterprise-ipv6-security-strategy-part-3-traffic-filtering-in-ipv6-networks-i/
https://insinuator.net/2015/12/developing-an-enterp
The goal isn’t to filter _all_ ICMP. The goal is to permit ICMP that is needed
for correct operation across the global network while protecting from
externally spoofed packets.
For example, on the IPv4 side, there arguably is no value to timestamp requests
and address mask requests externally,

I tend to agree. But if you still want to do it, then there is some
advice in https://tools.ietf.org/html/rfc4890

Good morning all,
I’m looking for some guidance on best practices to secure IPv6 on Linux end
nodes parked in AWS.
Boxes will be running various services (DNS for starters) and I’m looking to
secure mainly ICMP at this point. Service filtering is fairly cut and dried.
I’ve reviewed some of
