For confirmation, you can go to the Help menu, choose Debug Window, and open the Information tab. In the Network section, it will tell you exactly how many inbound connections you have. If the number is greater than zero, then inbound connections are allowed.

In the bottom right corner of the Bitcoin Core GUI are several icons. If you hover over the signal strength icon, it will tell you how many connections you have.

If your node has been online for at least 30 minutes, it should normally have inbound connections. If want to check your peer info using Bitcoin Core, choose the appropriate instructions below:

Peer info in Bitcoin Core daemon

For confirmation that you accept inbound connections, you can use Bitcoin Core. Bitcoin Core can’t tell you directly whether you allow inbound connections, but it can tell you whether or not you currently have any inbound connections.

After you press Check Node, the tool will inform you whether your port is open (green box) or not open (red box). If you get the green box, you don’t need to do anything—you accept inbound connections. If you get the red box, please read the enabling connections subsection.

Once you’ve done so, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the Bitnodes page. The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. Before using BitNodes, you must first ensure that your node is fully synced with the block chain.

Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.

Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333.

Bitcoin Core Daemon
To start Bitcoin Core daemon, first open a command window: press the Windows key (⊞ Win) and type “cmd”. Choose the option labeled “Command Prompt”.
