sympl-firewall: Traffic on the local IPv6 network can trigger blacklisting of the LAN
Sympl will track IPv6 traffic at a /64 resolution, but this means if something on the same LAN is flagged and blacklisted, it will effectively disable IPv6 traffic from the same /64, which can interfere with monitoring or similar.
What should probably happen is that Sympl is a bit more granular with it's filtering of V6 addresses on the same /64, and instead only blocks individual IPs if it sees them acting suspicious.
