So I recently moved and the apartment I now live in shares the internet with the main house. I want to setup my personal router so that all ports are open in the main router to my router. So that I can open ports whenever I need, without fiddling with the main router. The reason I'm asking this and not following a generic tutorial, is because I've already tried doing this. And in doing so, messed up the internet for every device connected to the router. I ended up switching to a manual DNS server for every device that my landlord owned to temporarily fix it until an IT dude could look at the router. The landlord never knew I messed it up in the first place, so fortunately for me he ended up thinking I was a networking god who fixed his internet issues. However, I'd rather not go through that again, so if anyone could point me in the direction of where I might find a specific guide to do this for the EdgeOS, or if you yourself could tell me what to do. I'd greatly appreciate it.
