Does your node respond to RPC commands? Does it have outgoing connections?

try to use 'netcat' from another machine connected to the internet. You must know your routers IP, and then try: $ nc <your_router-ip> 8333 - see if it replies. You can use netcat against webservers in the internet with IP address and port 80, to get a bit familiar. This will tell you if your port is really open or not. Some network skills and experience is beneficial :-)

Are you familiar with Linux/Debian? Know how to search for processes, that might run a firewall?

I went to a port scanner and it said port 8333 was replying, but when I went to the bitcoin node testing site it said it wasn't responding. Maybe it is because the blockchain is not downloaded yet?

As far as I can tell there is no firewall running.

# Full Node Not Taking Incoming Connections

(Asked by: username_0 on 2017-07-08)

I set up an RPi3 with Bitcoin full node 13.2. It is running Raspbian the latest version and is up to date.

My router has a static IP on the public internet. My RPi3 is behind NAT.

I configured my router to port forward 8333 to my RPi3.

The RPi3 is pretty much stock, so I don't think there is a firewall running. If there is I don't know about it or how to configure it.

The bitnodes site says my RPi3 is not accepting incoming connections.

Any ideas?
