If I want to change the discovery port from 30303 to XXXX I do "parity -port XXXX". But what if I want to change 30304/udp?
For example, maybe I have many computers NAT behind a firewall. I can do port forwarding for the discovery port 30303, XXXX, etc. and invoke those individually on the command line. But how do I do this with 30304/udp?
