Topic isn’t totally accurate. If UFW is used outside docker, as ”normally” on VPS, it doesn’t apply per se with Discourse. I can disable port 80 and it is still wide open to Discourse/docker. Sure, it protects everything else but if there isn’t any other services listening it is unnecessary. I don’t know how UFW or iptables works if used after `enter app` or can firewall use that way at all. I’m referencing to this topic: > [@Will UFW limit Discourse too?](https://meta.discourse.org/t/will-ufw-limit-discourse-too/231873): > > How can Discourse bypass UFW? I had enabled only port 22 so all other ports should be closed then. But a forum worked anyway. How’s that possible? DigitalOcean droplet, but that should not mean anything. And no one-click install, but official way. This is not a pure support question, but we don’t have here a catogory named Stupid basic questions by beginners wink --- _[View the full topic](https://meta.discourse.org/t/configure-a-firewall-for-discourse/20584)._
