Packets duplication / Netem

Hi everyone,

I would like to duplicate every outgoin packets for testing purposes, the idea behind is minimizing for exemple packet loss on the road to the server.

I got a linksys wrt3200 which is a dual core and thus havin eth0 for lan and eth1 for wan, which interface do i set the duplicate queue on ?

actually been testin this command on eth0 :

tc qdisc add dev eth0 root netem duplicate 100%
