Build Status

Puppet UFW Module

Module for configuring UFW (Uncomplicated Firewall).

Tested on Debian GNU/Linux 6.0 Squeeze and Ubuntu 12.04 LTS with Puppet 2.7. Patches for other operating systems are welcome.

Usage

If you include the ufw class the package will be installed, the service will be enabled, and all incomming connections will be denied:

include ufw

You can then allow certain connections:

ufw::allow { "allow-ssh-from-all":
  port => 22,
}

ufw::allow { "allow-all-from-trusted":
  from => "10.0.0.145",
}

ufw::allow { "allow-http-on-specific-interface":
  port => 80,
  ip => "10.0.0.20",
}

ufw::allow { "allow-dns-over-udp":
  port => 53,
  proto => "udp",
}

You can also rate limit certain ports (the IP is blocked if it initiates 6 or more connections within 30 seconds):

ufw::limit { 22: }

You can also adjust the ufw logging settings

ufw::logging { "prevent-logging":
    level => 'off',
}
