# Rocky Linux comes with firewalld enabled. It blocks some of the network
# connections needed for our k3s cluster. For our test setup, we just disable
# it since the VM host's firewall is still active for connections to and from
# the Internet.
# When building your own cluster, please DO NOT blindly copy this. Instead,
# please create a custom firewall configuration that fits your network design
# and security needs.
