[SOLVED] ELI5: How to put several servers on one external IP? (lemmy.today)

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!

Or he just uses a reverse proxy like nginx. So all can be hosted behind the same port (443)

I would use Caddy or something else that is less complex to setup

[–] melroy@kbin.melroy.org 1 points 4 days ago

Yeah Caddy is also a great option.

Something we didn't had a decade ago. Then the most likely approach was either apache or nginx.

Not yet, but want to figure it out properly.
