I would get these for time to time. I do not know what IP Option 0x14 is specifically, but I seem to recall tracing it back to some load-balancer devices. If anyone knows what it means for sure I would be interested in a definitive answer. ----- Original Message ----- From: "Miller, Dan" <dmiller () MICROTHERAPEUTICS COM> To: <INCIDENTS () SECURITYFOCUS COM> Sent: Tuesday, October 31, 2000 11:04 AM Subject: PIX Question
I am a 'newbie' to Security and have been a voyeur to this list-server for a while - plus the 'education' - so please be gentle... Recently the following message has been picked up at our PIX firewall: 106012:Deny IP from 0.0.0.0 to 161.58.250.155, IP options: "0x14" My question is what is an 'IP Option 0x14' ? Just from the outside IP address I assume this to be some kind of attempt to map or penetrate the network perimeter... Any other opinions? Thank you in advance.
