Title: Full Node Inbound Connections
Post by: snerd on June 10, 2024, 03:54:53 AM
Howdy! I had to reinstall Windows, so I guess it allowed Bitcoin Core to allow incoming connections. Right now I have 38 Inbound and 10 Outbound connections. Is this right? Safe?

This is safe, your node needs to establish outbound connections with other nodes to get the latest copy of the blockchain and stay in sync. You may have not allowed inbound connections before the reinstallation.

By default you can have a maximum of 10 outbound connections and 115 inbound connections.

Safe?
Relatively safe as long as you're not using "UPnP" in router and Bitcoin Core settings to enable inbound connections.
If you somehow used that option, consider using "port forwarding" instead.

It's showing inbound connections, so yes.

If you allowed Bitcoin Core through Windows' firewall, then that should be enough setting OS-wise.
Usually it's the router or ISP that cannot map Bitcoin's P2P port without manual settings so your previous router settings must be intact (since you just reinstalled your OS).
