If the IP address that is associated with your domain name via DDNS is exactly the same IP address you type manually, then this should not be possible.

 

Can you please give more details how you performed the speed tests?

I know, thats why im concerned. My test is performed just by downloading large video files from my server. When i connect to the server via an ip adress, i reach speeds of around a full gigabit. When i connect via the ddns name its only 200-300mbps. I tested via ftp, samba, windows file share, hosting files on apache website. Same results

Is that file server connected to the LAN network of your Archer AX10? And the Archer AX10 has a Gigabit Internet connection through which you download these large video files to another computer that is connected to another Gigabit Internet connection? 

 

Yes. I get normal speeds when I connect directly via my ip, and limited when via the ddns name

Can you do a Trace Route from the remote computer to the Archer AX10 and then check whether the two routes are identical or different? Like what is shown in the screenshot below, but using your domain name and your IP address instead.

the routes are the same. I dont have a clue why the speed is limited
