Hi without going into hideous detail my problem is the following: I've been trying to divide outgoing bandwidth across a NAT'ed linux-2.4 router using iptables to mark packets based on (internal) source ip number and then tc filter with the fw classifier. The problem is that outgoing packets don't seem to be picked up by the tc filters at all, though they are marked correctly in the iptables mangle table. An analogous arrangement worked perfectly with ipchains + tc filter fw classifier. Has anyone else had a similar problem. If so any pointers would be appreciated. Regards Nick Gresham.
