12 A firewall is an invaluable tool in the sysadmin's toolbox. However while low-level firewalls such as iptables and pf are incredibly good at what they do, they are generally not able to handle application-layer rules.

14 The goal of mod_firewall is to provide similar services at the XMPP layer. Based on rule scripts it can efficiently block, bounce, drop, forward, copy, redirect stanzas and more! Furthermore all rules can be applied and updated dynamically at runtime without restarting the server.

18 mod_firewall loads one or more scripts, and compiles these to Lua code that reacts to stanzas flowing through Prosody. The firewall script syntax is unusual, but straightforward.

20 A firewall script is dominated by rules. Each rule has two parts: conditions, and actions. When a stanza matches all of the conditions, all of the actions are executed in order.

29 FROM is a condition, and DROP is an action. This is about as simple as it gets. How about heading to the other extreme? Let's demonstrate something more complex that mod_firewall can do for you:

78 *Note:* The type 'available' for presence does not actually appear in the protocol. Available presence is signalled by the omission of a type. Similarly, a message stanza with no type is equivalent to one of type 'normal'. mod_firewall handles these cases for you automatically.

82 INSPECT takes a 'path' through the stanza to get a string (an attribute value or text content). An example is the best way to explain. Let's check that a user is not trying to register an account with the username 'admin'. This stanza comes from [http://xmpp.org/extensions/xep-0077.html#example-4 XEP-0077: In-band Registration]:

102 That weird string deserves some explanation. It is a path, divided into segments by '/'. Each segment describes an element by its name, optionally prefixed by its namespace in curly braces ('{...}'). If the path ends with a '#' then the text content of the last element will be returned. If the path ends with '@name' then the value of the attribute 'name' will be returned.

104 INSPECT is somewhat slower than the other stanza matching conditions. To minimise performance impact, always place it below other faster condition checks where possible (e.g. above we first checked KIND, TYPE and PAYLOAD matched before INSPECT).
