In September 2007 Patrick McHardy, who led development for past years, was elected as new chairman of the coreteam.

In April 2004, following a crack-down by the project on those distributing the project's software embedded in routers without complying with the GPL, a German court granted Welte an historic injunction against Sitecom Germany, which refused to follow the GPL's terms (see GPL-related disputes). In August 2003 Harald Welte became chairman of the coreteam. The software they produced (called netfilter hereafter) uses the GNU General Public License (GPL) license, and in March 2000 it was merged into version 2.4.x of the Linux kernel mainline. As the project grew, he founded the Netfilter Core Team (or simply coreteam) in 1999. Rusty Russell started the netfilter/iptables project in 1998 he had also authored the project's predecessor, ipchains. Relation of (some of) the different Netfilter components
