Supporting the netfilter/iptables project

By answering questions asked by fellow users on the mailinglists, you can enable the netfilter/iptables developers to spend more time with development, rather than answering to questions. This, in turn, will make new features available faster.

The most obvious way to help us, is development. If you are no developer, skip this section. There are many other options on how you could help us

If you write any extension for netfilter/iptables, please make it available under the GNU GPLv2 and contribute it by sending a patch.

If you are a developer, but don't have any idea in which area of the project you could work on: Please contact the coreteam, and we will will give you suggestions on a specific task you could do.

Please note that within netfilter/iptables (as part of the kernel), we strictly adhere the Kernel CodingStyle. Please also consider reading SubmittingPatches as a good starter in how to prepare patches in a way to make it easy for the maintainers of free software projects.

We are always happy about donations in any form.

If you are a corporate user or vendor, we would gladly accept any donations, either monetary or in goods (hardware, ..). We assure you that any donation we receive is very much appreciated and used for further development of the netfilter/iptables software.

If you are interested in making a donation, please contact netfilter core team.

To see which companies and individuals supported us with donations in the past, please see the Thanks section.

As you will have noticed, the documentation is sometimes outdated and incomplete. If you notice some missing, outdated or incomplete item of documentation, please send us a patch against the original SGML/XML source of that document.

If you write any kind of netfilter/iptables related document, e.g. for a local LUG presentation, please send it to us, so we can discuss publication on our website.

If you are a native speaker of a foreign language (i.e. not english), you could translate our HOWTO's or FAQ to your native language. This way you can help users who have difficulties understanding english.

Please contact us in advance before you start your translation to minimize the amount of duplicate work (somebody else could be working on the same translation without you knowing it).
