8 /8-Stream / 9-Stream - Networking Support • Re: CentOS cannot be ping and ssh

You nft output shows that:
  1. You have firewall rules. The firewall is not "down"
  2. These rules are not generated by firewalld.service. Something/someone else has added them
  3. The shown rules drop everything that tries to come in (but do not block existing connections)
That explains why ping and ssh from outside never get reply from the server.
