I’m pretty new to selfhosting and homelabs, and I would appreciate a simple-worded explanation here. Details are always welcome!

So, I have a home network with a dynamic external IP address. I already have my Synology NAS exposed to the Internet with DDNS - this was done using the interface, so didn’t require much technical knowledge.

Now, I would like to add another server (currently testing with Raspberry Pi) in the same LAN that would also be externally reachable, either through a subdomain (preferable), or through specific ports. How do I go about it?

P.S. Apparently, what I’ve tried on the router does work, it’s just that my NAS was sitting in the DMZ. Now it works!

    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 - 81 is exactly the default port for nginx proxy manager. I just tried to expose it as a testing example, and already closed it back after a success (apparently port forwarding worked just fine, it’s just that DMZ messed with it)

      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.

            It seems you are missing some very basic knowledge, if you have questions like this. Watch/read some tutorials to get the basics, than ask specific questions.
