HI guys, This is my first server built and I'm following the article "Unraid Security Best Practices" This is probably a noob question, but I'm confuse on the part where it says do not expose to the internet /DMZ. What do they mean by that. I currently have from my server an ethernet cable to my Att&t router. Is that correct? Also should I get another router or Att&t router should be fine? I haven't move any data yet and just trying to secure it before I move any data. Also where they say review router port mapping where do I find that in my router setting. Sorry I'm new to this and hoping to learn. Thanks
