Hey guys, I'm looking for help here as a last resort. Can't find a solution..

I want to drop events from Win firewall log

the line is:

> message  
> 2022-12-02 08:53:10 ALLOW TCP 127.0.0.1 127.0.0.1 50740 389 0 - 0 0 0 - - - SEND

I don't want to send every line which contains **127.0.0.1 127.0.0.1**

So I tried literally tenths of regex combinations and nothing worked. All event's still come threw to my Graylog server.

```auto
processors:
    - drop_event:
        when:
            regexp:
                message: '(127\.0\.0\.1).(127\.0\.0\.1)'

```

```auto
processors:
    - drop_event:
        when:
            regexp:
                message: '\s\b(127\.0\.0\.1)\b\s\b(127\.0\.0\.1)\b\s'

```

etc etc..

Is there an obvious mistake? Please help
