Support #3013
closedThe rules detect order
Description
Does suricata detect the rules which action is "pass" at first;Then the rules with "alert"\"drop"?
And if two rules have the same action like 'alert',suricata will detect the rule which have a small id?
I just want to known the order that how suricat detect the rules.
Please give me some suggestions,thank you very much!

Normally "pass" always comes before "alert" and "drop".
(for the order within alert rules itself I'm not sure if it can be predicted)

yes,if rules have a same proto,"pass" always comes before "alert" and "drop".
But when I use rules with different proto,it seems rules with "ip" have a first priority,then "tcp | udp",the last is "alproto".
So I want to known can I change the priority like "alproto","tcp | udp",the last is "ip".
If you have any good comments, thank you very much !

I don't think there is a way to change that order, although I see that it might be relevant for the IPS mode where you want to drop traffic.
