Does Flatcar have host based firewall (iptables/nft) configured to drop all incoming connections by default (except for the ports used by flatcar)? Asking for security compliance. |

No, Flatcar does not ship with firewall rules by default. It is up to the user to configure the appropriate firewall rules through ignition. |

The only port used by Flatcar by default is port 22.
