Good morning, I need help please, I tell you, I am installing docker on a physical host within a lan, when I finish installing it it no longer lets me ping, access cockpit, or ssh, I have another linux computer to which I connect ssh and from there I ssh to my host with docker, so if I can work, I don’t know why iptables blocks me, although I reset iptables, the problem continues.
$sudo iptables -L -n -v
