Maybe there's something wrong with your approach or test environment. As
long as there's no comsat or any other service running on this port, and
you do not actually trash your link layer, there's absolutely no reason
for this to succeed. It is normal, system-generated UDP packet, and
apparently, as expected, has no impact on boxes I can reach from there...
