Is there any way to connect NOT LOCAL node to running private Blockchain? So, there are 3 virtual machines in one local network. They are syncronized private blockchain. They have static-nodes.json and same genesis.json. One of this virtual machines has connection to Internet and mapping from port 8545 from white IP to local IP address. I want to connect there one more node, but this node is not in local virtual machines's network. Is there any chances to do it? Maybe some parameters rpcallow and so on? Hope, somebody can help me and clarify this question.
