Thank you @scanham!
I already use Littlenavmap & Littlenavconnect and it works good on 2nd PC.
Also Navigraph with its own Simlink software works on the 2nd PC.
But I am looking for a solution to have simconnect running on a 2nd PC with a connection to the MSFS PC so I can run Tools on the second PC which do not have their own network bridge solution.
Neofly is just the first software I use without its own simmconnect network solution.
