  • It is a bad idea to expose your rpc server online, be carefull !!! – Badr Bellaj♦ Oct 2 '18 at 23:01

I suppose you want to restrict outbound as well as inbound connections. There is parameter allow-ips for filtering outbound connections in parity, not sure about geth

--allow-ips FILTER Filter outbound connections.

It can help partially, but I think it would be better to do it on OS level.
