Lite nodes have basically two types of interfaces: Node info (via RPC) and Communications (via edge). These interfaces are made available on a few different ports to facilitate communications through firewalls etc…
Your node will be able to relay traffic if only one port from the Communications interface is available.
However, typically you’ll want to get port 8545 open on your node first so that your Diode™ Network dashboard connects.
Node Info / RPC Ports:
- 8545 → Primary RPC port (e.g. used by Diode™ Network and dashboard)
- 8443 → RPC via SSL
Communications / Edge Ports:
- 41046 → Primary communications port
- 443 → Communications over SSL
- 993,1723,10000 → Other available ports
