Hi I am running a Linux firewall (kernel 2.4.18 with newnat). I have enabled ECN on our servers - but that gives problems, as some routers are *still* not ECN-compatible.
In order to annoy my users as little as possible, I am trying to strip off the ECN bits for problematic sites - but I simply cannot get the ECN target working: root@wiibroe:~# iptables -A PREROUTING -t mangle -p tcp -d www.xcse.dk -j ECN iptables v1.2.6a: ECN target: Parameter --ecn-remove is required Try `iptables -h' or 'iptables --help' for more information. root@wiibroe:~# iptables -A PREROUTING -t mangle -p tcp -d www.xcse.dk -j ECN --ecn-remove iptables v1.2.6a: Unknown arg `--ecn-remove' Try `iptables -h' or 'iptables --help' for more information. root@wiibroe:~# The latest CVS snapshot gives the same result. Can anybody see, what I am doing wrong? Is it a problem with the kernel configuration or what?
