Block Suricata Rules

I just installed a fresh copy of 16.7.r1 in a small production environment.  I'm testing out the Suricata Intrusion Detection feature.  I currently have it setup to alert and not drop anything so that I can gather some information for tuning before I drop.  However, when I disable a rule in the "Rules" tab by unchecking the "Enabled" box for the rule, I still keep getting alerts.  Even after a reboot, the rule is still unchecked but the alert for that rules keeps happening.  Any advice would be appreciated.

I'm not sure what was happening the first time, but since the last Rule download and update everything appears to work as I would expect.  I can now manually disable a rule and it actually appears to disable.

If that should happen again, please let us know.

Hi Sundial,
i just have tested this and its seems to be ok on my VM OPNSENSE.
Just to double check, after changing the rules from drop to alert, , you have to download the rules again and apply them.

Not any more.  I downloaded the rules initially and then after getting lots of alerts, I tried to disable them (including clicking Apply on the Rules tab).  The rules never seemed to "Apply".  Then I manually downloaded the rules again.  After the second manual download everything is working liked I'd expect and I can't repeat the "bad" behavior or explain it.  During the bad times, I was having some random, intermittent web interface issues (..it would freeze or have extra long pauses and sometimes require restarting...and yes, I was very patient waiting several minutes...and the machine is a quad core i3 with 4GB RAM and SSD).  Perhaps the web interface issues are the real culprit.  However, almost all of those issues are gone now even though I haven't really changed anything but did reboot a few times.  I'm sorry I can't provide real diagnostic information, but everything has been working as I'd expect for over a day now.
