On the accesspoint I saw that although I changed the ethernet address of the wireless nic to that one of the wired nic (checked with ifconfig) connection was tried to be established with the native mac of the wireless nic. Now I'm using the native mac of the wireless nic on the wired nic to avoid this problem. This didn't solve the lagg issue. While I was pinging a client reachable through wired and wireless lan I observed traffic on the three interfaces (bge0, wlan0, lagg0). With cable connected I saw ping traffic (in & out) on lagg0 and bge0. When removing cable after a small break I only saw outgoing packages on lagg0. IP and ethernet addresses of outgoing packages were the same in each case. Regards, kaltheat
