Maybe the person who was attacked from that address can do a trace to it ? Obviously THEY have a route to it.

No, you don't have to have a route (back) to A.B.C.D to have a packet arrive with a source address of A.B.C.D. It might be nice if that were the case in every router, but smurf can be effective just because this is _not_ the case (as applies to the originating echo requests). -- -- *-----------------------------* Phil Howard KA9WGN * -- -- | Inturnet, Inc. | Director of Internet Services | -- -- | Business Internet Solutions | eng at intur.net | -- -- *-----------------------------* philh at intur.net * --
