[Server] Cannot connect to Server via Internet

[Ahnde]

Hi,

I recently set up a private server on my Synology NAS.
The server runs in a Docker container (https://github.com/factoriotools/factorio-docker).
The version of the game is 'stable' (0.17.79), so the currently up to date version.

My router forwards UPD Port 34197 and TCP Port 27015 from anywhere outside to the internal IP of my smart NAS.
The smart NAS is configured to map those ports to the Docker container.

Basically I did all the settings identically to setting up a Minecraft and a Terraria server, which both work.

But still I cannot connect to the server, when I enter my external IP. (even when my client is not in the same network as the server, to exclude any issues there)
On the other hand, if the client is in the same network and I enter the internal IP of the smart NAS, I can connect to the server.

So the question is:
Why could the connection to the server not be established via Internet?
I am somewhat clueless where to look for the issue.

The server config contains a username and the token.
It is set to public and is shown in the public server list. (But not ping-able)

Here is the server log:

EDIT: For testing reasons I shortly added a new Firewall rule, which allows every(!) connection to my NAS. The issue is unchanged.

Kind Regards,

Hi,

I solved my problem and as usual it was in front of the screen...
The issue had nothing to do with Factorio, but with my NAS.
I have 2 LAN Ports on the Synology NAS. I connected both to my Unifi Switch and forgot to enable Link Aggregation.
Ergo my switch interpreted those two connections as two different devices, which retrieved two different IPs by my DHCP Server.
And of course the wrong IP was used for Factorio, so my port-forwarding was not working.

Now I aggregated those two LAN Ports on my Switch and in the NAS -> everything works flawless.

Cheers

Thank you
I solved it in the same way
