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!

A scheme of desied network. NAS, available by nas.example.com, and Raspberry Pi, available by pi.example.com, are connected to a router, which gets DNS data

Not sure why you're downvote, you're absolutely right. People scan for open ports all day long and will eventually find your shit and try to break in. In my work environment, I see thousands of login attempts daily on brand new accounts, just because something discovered they exist and want to check it out.

    Those who have not been burned yet often don't expect it to happen to them. Usually it isn't anything big causing it but some typo in a config or software not updated on time.
