Hi there! I anew to this mailinglist, so I hopmy question is fitting here and not too "basic". I would likto affeconly some traffic with netem. Could someone give an example, how to delay traffic from a certain ip-adress only (or any u32 filter)? Just a plain, simple example... I ausing two bridged NICs and thLinux Kernel 2.6.35. I am aware of the example explained here: http://www.linuxfoundation.org/collaborate/workgroups/networking/netem#Delaying_only_some_traffic Pretty much whaI wanto do, except for the TBF to do ratecontrol at the end. Unfortunatelly, it is not working in my case. Which device do I have to use? Bridgeinterface (br0) or one of the NICs (eth0 or 1)? I read about changes in the use of netem, when it comes to leaf classes. Does this affect this example? I also looked through the threads of this archive from the whole last year and I know the LARTC HOWTO page pretty well. Somehow I don'seeto get a filter running properly... I really spent many hours on this and would be very thankful for any advice. Regards, JP -- GMX DSL Doppel-Flaab 19,99 Euro/mtl.!
