In that case tcpdump on the output interface will show bad checksums as the checksum gets calculated later on by the card. If you tcpdump on another computer in the same LAN you'll see the wake-on-lan packets with correct checksums. > Thanks for helping, You're welcome. > MarKus Regards, Paul Schenkeveld
