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!
You'll need to direct that port for the given service in the router control panel.
For your current server you have a port forwarding for that port already. Just add a port forwarding rule for the new service.
Tried doing that - here's how I've set it up:
Expected behavior: now when I enter :8100, I reach 192.168.0.113:81
Real behavior: connection times out
Stupid question, but is the service reachable at all? What if you map 81 to 81? Or whichever port the other, confirmed-to-work service uses? What if you map that other service to 8100?
Reachable through LAN, but not by URL, even if I port 81 to 81
P.S. Solved! NAS was sitting in the DMZ and this broke forwarding.
What if you try reaching it through your public IP?
Worked eventually, was about DMZ on the router for my NAS
