Set up ufw in Debian-like systems.
|
|
|
|
#### Requirements
|
|
|
|
None
|
|
|
|
#### Variables
|
|
|
|
* `ufw_default_incoming_policy` [default: `deny`]: Default (incoming) policy
|
|
* `ufw_default_outgoing_policy` [default: `allow`]: Default (outgoing) policy
|
|
|
|
* `ufw_logging` [default: `off`]: Log level
|
|
|
|
* `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_default_application_policy` [default: `SKIP`]: Set the default application policy to `ACCEPT`, `DROP`, `REJECT` or `SKIP`. Please note that setting this to `ACCEPT` may be a security risk
|
|
* `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
|
|
* `ufw_etc_default_ipt_sysctl` [default: `/etc/ufw/sysctl.conf`]: IPT backend, only enable if using iptables backend
|
|
* `ufw_etc_default_ipt_modules` [default: `[nf_conntrack_ftp, nf_nat_ftp, nf_conntrack_netbios_ns]`]: Extra connection tracking modules to load. Complete list can be found in `net/netfilter/Kconfig` of your kernel source
