Error with filters

Hi guys.

We have recently updated the versión of our Zeeks to the last stable 3.1.1 from 3.0.1

My problem is that in the previous version we had a filter that worked perfectly and now in the new version it doesn’t work anymore.

The filter is in the end of the local.zeek file and is the next one:

redef restrict_filters += { [“hosts”] = " not host 172.22.96.200" };

I don’t know if it is a bug or we have to write the filter differently but it doesn’t work in the new version.

Thank you,

Regards.

Is zeek returning an error or is it just not filtering? Is the filter listed correctly in packet_filter.log? I tested the same filter redef here with a test file and it appeared to be working.
