Comment on ELI5: How to put several servers on one external IP?

• infeeeee@lemmy.zip ⁨2⁩ ⁨days⁩ ago

  External 80 to internal 80 and external 443 to internal 443

  With this config you don’t have to deal with ports later, as http is 80, https is 443 by default.

  If you run some container on port 81, you have to deal with that in the reverse proxy, not in the router. E.g. redirect something.domian.tld to 192.168.0.103:81

  If you use docker check out nginxproxymanager, it has a very beginner friendly admin webui. You shouldn’t forward the admin ui’s port, you need to access it only from your lan.

    Actually, I do and you guessed it by the port correctly. I just tried to expose it as a testing example.

    And since we’re talking about this, what do I do with it next? I have it on my Pi, how do I ensure traffic is distributed through it as a reverse proxy? Do I need to expose ports 80 and 443 and then it would work automagically all by itself?

      You type the ip of the rpi on the router, so from an external call the router will forward it to the rpi. Or I don’t know what is your question.

      Things may seem automagical in the networking scene, but you can config anything the way you want. Even in nginxproxymanager you can edit the underlying actual nginx configs with their full power. The automagic is just the default setting.

        Where do I type rpi’s IP, just in port forwarding? Or somewhere else?

        I want for Nginx proxy, controlled through the Manager, to direct traffic to different physical servers based on subdomain.

        I put in nas.my.domain and I get my Synology on its DSM port. I put in pi.my.domain and I get a service on my Pi.
