How to change Parity's TCP and UDP port to run an Ethereum node?

Question

As far as I am aware the ports 30303/TCP and 30303/UDP, 30301/UDP have to be accessible from the internet in order to run an Ethereum node.

I am running Parity and am sitting behind a firewall which only opens a small set of ports for me.

Is it possible and if yes how to change the ports using Parity?

Answer 1

Have you tried the following parity cli options?

• --port PORT Override the port on which the node should listen
• --jsonrpc-port PORT Specify the port portion of the JSONRPC API server
