This is a virtual device. You can redirect packets with iptables to it and you can do it on incoming/outgoing and from different NIC's. So you can limit download + upload together like you want.

[LARTC] Traffic shaping for upload download
Lets say we want to limit a customer usage to 256kbit total. That is, you want to limit upload+download. Whether or not it can be done, I think it's worth pointing out that this is nonsense. It makes sense to allocate A+B only if A and B can be used to replace each other. Upload and Download are not like that. They're more like food and air - you need both. If you have no air it won't do any good to be given more food. In your case the analogous thing is that you have a total of 1Mbit up and 1Mbit down available, two users, and you allocate 1Mbit total to each. One decides to attack the other by using 1Mbit upload. You decide that's fair, the other (the victim) can just use 1Mbit download. Well, maybe he can, but it won't do him any good. I suggest instead that you allocate upload and download bandwidth separately. ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
