Hi,
I've come across a situation during my dual stack implementation.
My WAN interface is using DHCPv6 (client). from that interface, I can ping the other side of the link on the local link address but not the LUA.
ping6: sendmsg: Permission denied
Any ideas? I've created rules on the interfaces but with no luck.
Thanks.
-----------------
Editing: an old floating rule screwed me over. Waste of day.
Probably worth to mentioning that a generic ipv6 block rule was not stopping traffic between link local addresses though, but everything else.
