This was discussed lately on the SNMP news list. There is no behaviour 
described by the standard in this case and it seems that both behaviours 
exist and are formally allowed. I would say that it would be good to make 
the response appear from the same IP address as the request was sent to. I 
try to look whether this can be done easily.
