Background
The RNode software runs as a server on the RChain network. The RNode communications software uses gRPC, which uses TLS to secure TCP connections between validators and read-only nodes. The RChain network is a peer to peer network. In order for a RNode server instance to properly communicate with the rest of the network, secure bi-directional communication must be possible. Validators must be able to send queries to each other and must be able to receive connections from other validators.
...
The RNode server needs to be directly connected to the router. The router needs to either support UPnP or have static NAT with port forwarding configured for ports 30300 40400 - 30330340440. If you wish to use a different set of ports, specify those at runtime with the --p option.
...
RNode supports the UPnP protocol, which is commonly available on retail routers today. When RNode detects a UPnP gateway device, such as your wireless router, the node software will configure the router's firewall rules automatically. In many small business and home networks, this allows the user to run RNode as a validator without having to reconfigure their network.
Note - Node operators running Docker on Mac OS X will not be successful running RNode with UPnP. If you want to run with Docker on Mac OS X, you must configure static NAT and port forwarding manually. See "Routers without UPnP Support" below.

Test your network
A success message means your configuration should be successful connecting to the RChain network. An error message means your network configuration may not be successful connecting to the RChain network. You need to investigate your configuration and possibly make changes. |

Successful Connection
You will know if that your node has connected successfully if you see connection messages in the console. Example:
