I would like to know how to only have certain ports open on my Asus router. I would only like to be able to browse the internet, torrent movies and shows via something like Plex or Kodi, play one to two online games and be able to turn my smart lights on/off and maybe setup IFTTT stuff and via my security cameras via an app on my phone or website. Would i just look up what port each of these activities use to access the internet? And also would i need to choose specific ports for each specific device that i use to go online with like the type of smart phone, pc, or tv i have? And the same with the smart lights and cameras i use? Or would the ports be more across the board for the specific type of device and not necessarily the brand and or model?
