      sorry for the formatting, what can i do to disable this behavior? I have allready readed into the forum but i can understand at all, i tried also a "Floating Rule" but no luck
      i have IPV6 disabled onto the pfSense (System: Advanced: Networking ->Allow IPv6 unchecked).

      many thanks
