I just changed the port on the other computer in the .cfg file and we both played a match, it didn't got me Auto-Disconnected yet... so I think this works now

It's most likely thanks to your help with the QoS rule

I just needed to use another port as well probably

Fingers crossed, hopefully I won't get problems now

Again, thank you for all your time, D-Link surely offers great support
