I have this Chain created, I think it is not the problem. I see this message in syslog: Nov 25 09:49:04 epia -- MARK -- Nov 25 10:00:05 epia kernel: MARK: targinfosize 4 != 8 I'm installing QOS in a embeded Debian on a Compact Flash, using the http://gate-bunker.p6.msu.ru/~berk/router.html script. I had to patch and compile kernel 2.6.9, iptables and iproute in another PC and I used debmake and debuild for build .deb packets, using the "Multi-binary" option in "deb-make". Debuild created the .deb files and I can install it tho the embeded...
