Alen, : can i add HTB rule on virtual interface? : example: eth0:0 First, it's not really a virtual interface--it's just a convention from the old days of IP aliasing to have names like eth0:0. The IP exists and is active on an interface, eth0 in your case. The short answer is "no". Traffic control occurs just prior to the release of the packet for transmission by the hardware driver. See the KPTD [0]. You can however select packets based on many characteristics, so you may be able to accomplish what you need. You'll use characteristics other than the label "eth0:0". -Martin [0] http://www.docum.org/stef.coene/qos/kptd/ -- Martin A.
