Guys,
So... has anyone been able to verify that the problem occurs when the TTL expires without the packet being addressed to the router? Or is it a requirement that the evil packet be addressed to the router?
As far as we know, the TTL has to go to 1/0 on the target IP address. Haven't been able to get the effect on a transit packet. Regards, tom. __________________________________________________ Security Consultant/Analyst CSC Ph: +61 8 9429 6478 Email: tcleary2 () csc com au ---------------------------------------------------------------------------------------- This email, including any attachments, is intended only for use by the addressee(s) and may contain confidential and/or personal information and may also be the subject of legal privilege.
