Hi all Sorry if i didnt found the answer in HOWTO's, mailing lists archives or any other place. and sorry if i write english like a spanish cow :P I'm currently using 'tc' to limit upload and stop breaking the connection of my cable modem. my eth0 has an ip alias eth0:1 which should not be limited by tc, but "tc qdisc add dev eth0" seems apply effect to eth0 AND eth0:1 :( Is there any smooth solution to leave eth0:1 in peace ? or do i have to limit effect with "ip src" and "ip dst" ? Regards, Gilles Dégottex
