Re: Difference between drop and reject rules

You have active responses enabled with the configuration below. That causes Snort to send TCP resets or ICMP unreachables when a session is blocked.

preprocessor stream5_global: track_tcp yes, \
...
   max_active_responses 2, \
   min_response_seconds 5

Thanks

Drop shouldn't send anything.  So if you are seeing this, we need your
configuration, rules, and a pcap.

Hi. Do you know why both drop and reject rules work exactly the same. The
manual says that drop rules must not sent RST packets but they do? Does
anyone know the reason?

Thanks
