in another post someones wrote,
Bitcoin nodes use to communicate with each other. You can disable incoming connections on your node if you don't like that (set listen=0 in bitcoin.conf).
Now i like to know if this is the only setting one must adjust to totally isolate her full node from other incoming/outgoing communications? Or are there any other steps u should take in addition to closing 8333?
Intention is: That the fullnode only interacts with ur own EPS server.
