i notice that i sometimes have connections (on several gateways with ROS) that seem to have problems with connection tracking.
Some connections are not detected as "established" so the ipv6 firewall drops packets even if they are part of a established connection. Most of the time this are https connections and sometimes normal http. I made a stateful firewall for ipv6 so i just allow incoming forward connections that are "established" and "related" but like i said, sometimes there are problems.
Anyone notice something similar?
