Arch firewall not allowing connecting ips?

I tried to do a zerotier and i could ping him but he wouldn't get any return packets from me

I tried to setup a FTP client server for some file sharing for a project im doing and (though i didn't get it working with error 530, using vsftpd) I noticed only my localhost could connect.

I decided to try something im relatively experienced with: minecraft servers... low and behold, i can only connect via localhost.

I disabled the service for the default firewall and nothing. It was working before my arch install, so i only see the OS as a variable; i've looked threw every setting in my router and it should be allowing all inbound connections. Im a lil bit confused.

Re: Arch firewall not allowing connecting ips?

What are the firewall rules on the system?

#nft list ruleset #for nftables based firewalls
#iptables-save #for iptables based firewalls

What ports were listening on the system?

ss -l -4 -6
