Greetings all... I write because i've been battlign a problem with tc for two days and I can't find a solution or a response to the failure... Basically I am trying to shape marked packages since I have a NAT and I discovered of course that I couldn't shape based on ip with the NAT in place, for the rule didn't apply... so I set a mark to the packages depending on the ip they came from, but then when I try to implement the filter to match these packages into a queue rule I get the following error from tc: RTNETLINK answers: Invalid argument The sytnax I am using is the following: /sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 1 handle 188 fw flowid 1:3 I've tried diferent syntaxes to no avail, I am thinking of trying to use an always-matching u32 rule instead of fw but I do not know if that is possible or if it'll ever work... also i've checked the kernel and I seem to have everything I need compiled, anyhow if someone sends me the list of options I need for this specific type of filter I can recheck... anyhow advanced routing is compiled, such as multiple tables.. and I have cls_fw as a module which loads correctly into kernel...... Any pointers please??? Thanks a lot.
