Take a look at the active module.  Try configuring active.min_interval.

Subject: [Snort-devel] snort3: reject rule problem


Hello

I have reject rule that send Port unreachable for ping.



It's Ok, but only for 1st packet.



The next ping packets are silently dropped and not detected and not logged.



reject icmp 192.168.0.1 any -> any any ( gid:8000; sid:1; msg:"ping";  )



This happens when stream and stream_icmp inspectors are in config.



If I remove stream {} and/or stream_icmp {} inspectors from snort lua config, then ALL OK: each packet is

dropped, logged and ICMP Port unreach is sending on each dropped packet.





Part of config:



stream={}

stream_icmp={}

reject={control="port"}



Thanks.
