All the material I find on the internet, is about sharing PC's internet connection with Rpi using the ethernet cable, and setting RPi static address etc.
However, My RPi 3B already has it's own wifi connection to the Internet. I don't need to share any internet connection between my windows 10 PC (also has it's own WiFi connection).
All I want is to be able to communicate internally between the two machines using the ethernet cable, while they're both connected to their own internet.
Is it possible, to configure the eth0 independently without affecting the wlan0 connection? I'm not sure that if I go ahead with a static IP config, will the RPi lose the usual wifi connection to internet?
Can you please give me some pointers on how to configure such a pure internal p-2-p connection between PC and RPi3b?
