I haven't looked at netfilter & 2.4, however this how-to covers doing just what you talked about: http://www.linuxdoc.org/HOWTO/Adv-Routing-HOWTO-8.html Jacob Anawalt ----- Original Message ----- From: " Zaborowski, Edward, SrA, AFPCA/SRW " <Edward.Zaborowski@pentagon.af.mil> To: <linux-net@vger.kernel.org> Sent: Wednesday, January 24, 2001 9:01 AM Subject: Net throttling > Does the new 2.4 netfilter have a way of throttling any/certain connections > based on IP, mac, or any other kind of method?
