- joegoodman 7y agoCool initiative!
- chanz 7y agoThanks for sharing this really looks cool. But there are some things that make me hesitate using it: 1. Maxmind: Since I don't know the company and it seems its only providing the geoip-database, my question is: Can it be disabled or left out at all? 2. Java: Its my personal preference to avoid using oracle products at all cost. Is openjdk an alternative? 3. Is the geo-graphical visualization all Pfelk can do? Is there a feature list or demo?
- notwedtm 7y agoFWIW, MaxMind is pretty much the defacto standard for geoip lookup tables.
- chanz 7y agoThanks, I was not aware of this.
- uaas 7y ago1: Well, it can be useful to map your src and dest ips to a map, but it can be left out, since the dashboards are fully customizable. Anyway, Maxmind GeoIP is widely used in this and other areas. 2: Yes, openjdk is supported 3: No, with this setup, you can extend the stock firewall functionality by forwarding everything to an ELK instance. You can search and visualize all of your firewall log entries with the full power of Elasticsearch. Yes, a complete feature list and/or demo would be great, we will work on those, thank you for your feedback. Feel free to reach out if you have any questions!

- ianai 7y agoWonder how I’d use something like this to nail down and block the advertising in stuff like embedded apps.
- CommieBobDole 7y agoPi-hole works pretty well for that - I don't see a lot of ads in phone apps when I'm at home. https://pi-hole.net/ https://pi-hole.net/
- nodesocket 7y agoThis is awesome. Anything like this for Ubiquiti EdgeMax gear?
- a3ilson 7y agoHypothetically yes and would only require adjustments. Although, I do not have any Unifi gear other than a couple of access points. I'll look into adding Unifi support in the near future.
- chaz6 7y agoThanks for making this! I would be interested in support for netflow so that it could potentially work with any capable router/firewall.
- a3ilson 7y agoNetflow is easily supported. However, it requires another instance of Logstash. Although ntopng does a phenomenal job with this, it can be easily included. I'll add, for consideration, as a future roadmap plug-in.
