Port forwarding
It is very important that you forward ports to both your Ethereum execution and consensus clients, this ensures you are able to peer with other nodes efficiently.
Your execution and consensus client will still run without port forwarding, but you may notice it will take a very long time to find peers, and you may struggle to connect with a meaningful number of them too. So it is in your best interest (and heavily recommended) to have them forwarded.
Below are a list of the default ports that the software(s) are set to listen on.
Execution client | Port(s) |
