See the documentation on configuration files along with the example configuration to understand how you can configure your node.
Accept incoming connections
Section titled “Accept incoming connections”When your node starts it will listen for node-to-node connections on the TCP
endpoint 127.0.0.1:5158. Select a different endpoint via the tenzir.endpoint
option. For example, to bind to an IPv6 address use [::1]:42000.
Refuse incoming connections
Section titled “Refuse incoming connections”Set tenzir.endpoint to false to disable the endpoint, making the node
exclusively accessible through the Tenzir Platform. This effectively prevents
connections from other tenzir or tenzir-node processes.
