as far as I know, it's very easy to send JSON-RPC request to a ETH node running with openethereum from LAN,

I want to know, what can I do to make this ETH node public, and allow people who is from external internet to visit?

e.g. in config.toml

[rpc]
apis = ["all"]
port = 8080
interface = "0.0.0.0"

OK I got it .

[rpc]
apis = ["all"]
port = 8080
interface = "all"  # this will do the work!

according to: openethereum -h, we can see the argument explanation:

    --jsonrpc-interface=[IP]
        Specify the hostname portion of the HTTP JSON-RPC API server, IP should be an 
        interface's IP address, or all (all interfaces) or local. (default: local)
