  If they are physically on the same ethernet, this should not be a
problem since MOP pays no attention to IP subnets. If they are
going through a bridge/router you may be in trouble. If it is 
strictly an IP router, you are in deep trouble. If there is a 
bridge component to the brouter, you may be able to coax it to
passing the MOP multicasts to entice your host to service it. The
multicast address is ab-00-00-01-00-00-00. Also you will need to
be certain the ethertype 60-01 will be passed through the bridge(s).

  Sorry, can't help you there. Most third party DS300 like things have
this ability though.
