Nobody has an idea to help me?

@teamits That seems to have worked. I guess maybe restarting the global service resets any global settings and restarting on the interface updates the interface settings but restarting the global service didn't seem to update the interface settings.

Yes, though usually attracting the attention of @bmeeks is the best way to get traction on this. 😉

No, it cannot.

@bmeeks said in Suricata inline whitelisting:

Suppress rules can be used to make sure no alerts are generated for a host. This is not efficient however, as the suppression is only considered post-matching. In other words, Suricata first inspects a rule, and only then will it consider per-host suppressions.

This means to me that the pass, drop, reject, etc., decision is made first and then the suppress list is checked to see whether or not to suppress the alert in the logs.  I need to dive into the source code for the Suricata binary and see if I can precisely determine how suppression affects dropping.

I need to dig into this some more before I can post a definitive answer.

Hi, did this get figured out/resolved? We may have run into this today on Suricata package v4.0.4_1...I suppressed an alert but the behavior didn't seem to change until I disabled the rule.
(FWIW it was rule 1:2013744 "ET INFO DYNAMIC_DNS HTTP Request to a no-ip Domain" which would make sense for dynamic domains but was for cdn.no-ip.com which is their actual domain. The rule only excludes www.no-ip.com.)

OpenAppID rules seem to download fine for me.

What interface are you running snort on ?

Run it on your LAN as you then see hosts pre NAT.

Yup the ping rule is a good test to see if snort is working.

If you change your ICMP rule slightly :-

alert icmp $HOME_NET any -> !$HOME_NET any (msg:“ICMP test”; sid:10000001; rev:001;classtype:misc-activity;)

alert icmp $HOME_NET any -> !$HOME_NET any (msg:“ICMP test”; sid:10000001; rev:001;classtype:icmp-event;)

It should block outbound ICMP traffic.

@nogbadthebad I wanna assume good faith here and that you're trying to help - but please try and not fall into the trap of first failing to read the OP, then insisting on a non-solution, followed by complete ignoring the OP altogether. I understand how to submit FRs - not my purpose here. Simply ignore the thread if you have nothing assistive to add.

Thanks.

i had the exact same issue on my box. so i removed it and switched to Snort which has always worked for me in the past. hopefully someone can shed some light on this
