I have seen the switch to allow inbound connections in advanced settings, but does it run over tor? Is there a way to route inbound connections over tor? Found this, but it’s not umbrel related: https://en.bitcoin.it/wiki/Setting_up_a_Tor_hidden_service
but if your computer is often online and you want to be a big help to the network, you can run a Tor hidden service in order to accept incoming connections over Tor.
