If it's protocol 0, instead of port 0, it's likely a packet-flooding DDoS attack. If it's port 0, you may be incorrectly blocking non-initial fragments. Alternately, it could represent a fragmented DDoS attack, either non-initial fragments fired directly against something on your network or as the result of a DNS reflection/amplification attack against something on your network. The log fragment you posted doesn't provide enough detail to make an informed judgement. Also, you should not place servers behind a stateful firewall, anyways. ----------------------------------------------------------------------- Roland Dobbins <rdobb...@arbor.net> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
