How is a LAN NET defined for an IPv6 network when the network is DHCPv6?
I am seeing blocks in my firewall for traffic originating on the LAN side to do things like DNS lookups or HTTPS traffic.
The rule that triggered this action is:
@5 block drop in log inet6 all label "Default deny rule IPv6"
OPNsense 15.7.15-amd64
FreeBSD 10.1-RELEASE-p19
LibreSSL 2.2.3

I did not have to enable DHCPv6 as SLAAC kicked in and is issuing everything just fine.

I changed the firewall from LAN NET to any and it allowed traffic to flow. Does this create an exposure?

Brandon, do you have specific info about the traffic being blocked (src/dst IP and port), it might simply be missing from the (internal) rules template.
