Hello,
I got a DDNS adress to reach my server from outside my LAN. That's no problem. But when I try to reach my server from inside my LAN through the DDNS adresse I always get an "Connection failed" error.
I know I can type in the local adress but in some programs on my Laptop and Smartphone the confguration ist set to the DDNS adresse because I often use them outside the LAN and it is not very feasible to change this every time.
Greetings
