Dear Andreas,
thank you for your explanation. That's what I suspected 🙈
And of course it makes sense.
The Problem is: In my old setup I directly connected my i-mac to the PC and therefore it was another Subnet
192.188.2.2 I thought this was a good idea not to go over the fritzbox and to keep it separated. But therefore I had to connect the PC via a second Networkoutput to the internet to have access to the internet. What had as a result that my i-mac allways found to ways of connecting to the PC. A bit confusing but...
Now as I bought a new mac studio I wanted to change this, and connect all computers via the fritzbox. But as this is another subnet I couldn't put the same IP address to the PC as before.
So now I have to decide whether to change all my projects to the new IP-address, or to change my setup again to the old way.
What would be your preferred setup. Connect via a router like the fritzbox or directly connect the computers?
Best regards
Frank
