Hello out there,
It's true, I have written down all the commands which are necessary to get ELK + Pfsense working together. It's fully tested and worked like a charm at a lanparty last weekend. So it was on a brandnew machine and on a different hypervisor. I will publish the tutorial in the upcomming week on wednesday. I also made all the commands with the newest Elasticsearch version: Elasticsearch-6.2.3.rpm for example.
The tutorial is based on a fresh CentOS 7 minimal installation. If you have a different operating system not all steps are necessary or will work as I described in the tutorial. You can always contact me via my website if you have questions and problems. I try to help as far I can. Maybe I will add a comment function later this year.
