Manageability packets sent to port 623 should be passed through to the
host networking stack, but there could be a mis-configuration of the
adapter hardware.  Which network adapter are you using?  Would it be
possible for you to also run our register dump utility ethregs(*) and
send us (privately if you would prefer) the output?
