It looks like the printout is faulty somehow, since the ARPs seem to
contain the 02:02: that you specified, and not the 12:34:... that is
(evidently) the default.
can you ping either 192.168.41.63 from your PC?
Is the routing and netmasks set up to force the 192.168.41.* addresses to
use the 10 gbe port?
What does netstat -r say on the PC and on the Roach?
Is the name of the GBE port "GBE0" or "gbe0"?
good luck!
