fw blocks package but existing rule exists

[Onkel-tobi]

Hi all,

i am on 24.1.9_4-amd64 and I don't have any clue why traffic is still blocked 8seeattachment dropped_packages).
It's regarding my home automation network and I have a general RFC1918 rule that denies traffic within the vlan.
Now I am trying to connect from device 192.168.178.30 (random tcp port) to 192.168.178.88 on tcp port 8083.
As you can see in my screenshots this traffic is blocked with the RFC rule. But before I have a rule that should pass that traffic. (see rule1 and rule_details).
Do you have any hints for me?

Thanks,
Tobias

Traffic from one system in 192.168.178.0/24 to another system in that same network should not pass through the firewall at all. Something's seriously wrong with your network setup. I'd check the netmask of all systems involved, first.
