Re: Alerts with the incorrect Source IP (proxy server)

What snort alerts what the IPs are from inside the packet. If you
tcpdump that same connection and you are seeing the proxy talk to the
client, and that's the packets that are making the alert then the way
to fix that is to move the span port location.  Snort only reports
what it sees and it can't 'infer' what the original source of the
packets are.

But more examples of your network layout and an example of the alert might help.

Hi Guys,



I’m getting alerts generated, but they are coming up as the source IP of my
proxy server.  Is there a way to tell Snort / Barnyard2 / Snorby that it
should report the IP address of the website instead?



Thanks,

Brad
