Iptables doesn't work correctly


I’m currently trying to figure out why some of my firewall rules are not working.

I’ve installed ZeroTier-One on my Virtual Server and connected it to my network. Now I want specific ports only accessible over the virtual network (My Zeortier IP Range). Somehow for example port 5001 is accessible with ZeroTier disconnected on my device.

Has anyone a clue why the firewall doesn’t close this Port?

I’ve installed Ubuntu 22.04 on my Server.

Here are my firewall rules I applied:

Thank you
