• ufw_rules [default: see defaults/main.yml]: Rules to apply

• ufw_etc_default_ipv6 [default: true]: Set to yes to apply rules to support IPv6

• ufw_etc_default_default_input_policy [default: DROP]: Set the default input policy to ACCEPT, DROP, or REJECT. Please note that if you change this you will most likely want to adjust your rules

• ufw_etc_default_default_output_policy [default: ACCEPT]: Set the default output policy to ACCEPT, DROP, or REJECT. Please note that if you change this you will most likely want to adjust your rules

• ufw_etc_default_default_forward_policy [default: DROP]: Set the default forward policy to ACCEPT, DROP or REJECT. Please note that if you change this you will most likely want to adjust your rules

• ufw_etc_default_manage_builtins [default: false]: By default, ufw only touches its own chains. Set this to 'yes' to have ufw manage the built-in chains too. Warning: setting this to 'yes' will break non-ufw managed firewall rules
