[MiNT] Weird ping reply
Hi,
I the following packet sniff there is a ping request and response
packets shown captured from an artificial network between Windows and
MiNT (SpareMiNT) installation running in ARAnyM. I wonder why the reply
HW address in the destination packet is not the source one taken from
the request packet. The Windows network is a bridge over two connections
if it helps.
Request:
> Destination: 00:41:45:54:48:30 (00:41:45:54:48:30)
> Source: 02:41:41:41:41:41 (02:41:41:41:41:41)

Perhaps there is something I am missing completely in netwoking, please
help.
