Yes and No :-)

I just examined the problem a little further and found out that only the
_outgoing_ packets have the wrong byte order, the incoming ones are fine.
Since the first packet in my hexdump example was incoming, that part was
correct in both files - sorry for the confusion.

I uploaded a small sample packet for an incoming TCP connection, which
shows exactly that the outgoing packets are byte-reversed:

The NSLU2 has MAC 00:14:bf:66:71:43 and IP 192.168.178.214.

Thanks for your help,
