[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!

Thanks! I got that advice as well, but I would like to keep it self-hosted - I consider using Pangolin on a VPS for that purpose going forward: https://github.com/fosrl/pangolin

Also, beware of the new attack on Cloudflare Tunnel: https://www.csoonline.com/article/4009636/phishing-campaign-abuses-cloudflare-tunnels-to-sneak-malware-past-firewalls.html

This attack targets end users, not Cloudflare tunnel operators (i.e. self-hosters). It abuses Cloudflare Tunnels as a delivery mechanism for malware payloads, not as a method to compromise or attack people who are self-hosting their own services through Cloudflare Tunnels.

Thanks for clarification!
