(Of course you could also directly send UDP packets with forged > source addresses...) How does this give anonymity? When sending to the server, I must use the servers address as a source address. When the server replies to me, it must use my address as a source address. Maybe the two addresses dont appear in the same packet at the same time, but they're there. This might fool a few people when used a few times, but it will hardly fool everyone when it is in widespread use. Tim N.
