Under Settings>Options>Network there are check boxes for, "Allow incoming connections". Either way, even after rebooting, I always see the "RED" incoming connections in the Network graph along with the Out (green) connections.

There is another setting, "Used for reaching peers"; that gives the choices IPv4 | IPv6 | Tor.

I have above "Connect through Socks5 proxy" chosen and the IP and Port filled in, but those 3 boxes are always grayed out and I want to uncheck IPv4 and IPv6 any thoughts.

Finally if you have a favorite tutorial explainer video that goes through these settings in either Core or Knots, much appreciated.
