3) When I test in bitnodes to check if I am reachable. In most cases it says I am not. however, sometimes it says I am.
That could also be an indicator of a problem with your firewalls, however generally this is hard to diagnose. If you want, you can PM me your IP address and I can attempt to connect with my own node.My experience is that if you are syncing, and your node has a high CPU load this test will time out before your node will reply. Since you sometimes have one incoming connection your setup is probably OK. If you want I can try to connect my node aswell. Just PM me the IP.
