I've only recently learned about the capture feature of my PIX firewall, so I have a lot to read. I started trying to view our inbound and outbound packets because of connectivity/speed issues that our company has been having lately. From reading the capture snippets on other sites, one thing that stands our right away are all the (fragment-packet) messages at the end of every line. I saw them during our period of poor/no connectivity, but also afterward once our Internet connection was (mysteriously) restored.
Here is a snip of the lines I'm referring to. Does anyone have any insight as to the severity of this message?
