Thanks for reply. Just to be sure. Is it better to stay with these firewall rules which i attached as image or just reset router to default router configuration with default ip firewall rules (different that on my photo)?

I have basic firewall rules from First Time Configuration tutorial: https://help.mikrotik.com/docs/spaces/ROS/pages/328151/First+Time+Configuration https://i.ibb.co/gLRrryGv/example.png And now I'm wondering: 1) Should I have this first position "passthrough" or maybe it should be deleted?...
