Hi Al, Thanks for the response. Unfortunately, I can not share the PCAP. Port 8080 is in the HTTP stream. How would I check for the proper http preprocessors? Interestingly, when i removed established from the rule, it worked. I am not sure why because the server responded with a HTTP OK. Thanks.

Hi, I have a situation where snort does not appear to be recognizing packets that I have in a PCAP. The packet in question is a simple HTTP server response. The rule is setup to read content in the packet. The server port is 8080. At this point, I can not figure out which configuration setting to change to get snort to parse the server response. Sample Rule: alert tcp any any -> any any \ ( \ msg: "Alert"; \ flow:from_server,established; \ content:"password"; \ sid:6000002; rev:1; \ ) Thanks.
