hi tim,

we probably need a little more context than just the "packet failed" 
line (at debug log level 5), but there could be a number of reasons why 
the packet could not be sent:

- you have broadcast-forwarding switched on on your network, and 
therefore you are receiving (and responding) to packets you shouldn't

- you have a firewall set up which is blocking packet sending to this 

- you have an incorrect "interfaces = " or an incorrectly detected local
interfaces parameter.  check the reported values for "interfaces = "  in the
log files (level 3 or above, i believe) against your broadcast/netmask/ip
address for that machine.
