Hello Matt, The reason for this is because Smartdefense is dropping the icmp packet. Smartdefense is kind of like having an 'mini IDS'. Among other things, it ensures that the icmp packet conforms to the max ping size as specified in the smartdefense configuration - which defaults to 64 bytes. As your log shows 'Packet data size: 75' this will be dropped, You can disable this on the firewall or configure the max size to something greater than the current value. Regards, Paul Dawson -----Original Message----- From: Matt Kehler [mailto:[email protected]] Sent: 22 August 2003 16:44 To: [email protected] Subject: [FW-1] icmp packet drops? Out of nowhere, I seem to be getting a lot of ICMP drops as per below. Any reason why I would be getting these out of nowhere? Since they are not rule generated; how can I turn off the logging on them? A setting in global properties I assume, or can I do it per enforcement module? NG AI on IPSO 3.7 build 23.
