Netfilter is a free/opensource software community-driven project, launched in 1998, that provides firewalling tools for the GNU/Linux operating system. The Netfilter Workshop (NFWS) is the main event organized for and by the Netfilter developers community. During the workshop days, Linux kernel networking and Netfilter developers meet and discuss the status of the on-going Netfilter-related developments and the plans for the near future.

Following the lastest successful NFWS in Montpellier, France. We are happy to announce that the next event in these series will take place in Budapest, Hungary, in dates 22th-26th June 2015.

The event will be hosted by the NIIF centre (Hungarian NREN) at the Victor Hugo street.
