I have private Ethereum network running on my local network with two sealer node and one bootnode. I have deployed the private blockchain and configured it using geth. Now I want to create another node from another network to connect to that private blockchain deployed. How can I do that if I want to access a contract from the new node?

It two different networks, you cant reach one from another.– Roman KiselenkoDec 20, 2018 at 8:28

@Зелёный can't the new node be created using the external Ip of the bootnode?– ludoDec 20, 2018 at 8:36

It's confusing when you say "another network". In most blockchain ecosystem, "another network" would refer to the difference between the Ethereum mainnet and another network like Ropsten. These 2 networks can't simply be connected. I'm assuming in your original post that you mean the literal definition of network, as in connecting a node over the internet to your local network?– natewelch_Dec 20, 2018 at 18:39

@flygoing I meant connecting a new node that belongs to a different local network to my private blockchain like connecting my pc at home to another pc in the office network– ludoDec 20, 2018 at 22:06

You need to use same genesis file for both private-networks and keep the networkId same.
The from first node type:
admin.nodeInfo
{
enode: "enode://7622844520524910d2ca3036c7e2e912a441ebfc13fad8d759046abe1a9d664cf5e09c5edb765ee0cfe64d64645f1b1b16cc6b2d1c4ec557e5eb96f09335f066@[::]:30312",
id: "7622844520524910d2ca3036c7e2e912a441ebfc13fad8d759046abe1a9d664cf5e09c5edb765ee0cfe64d64645f1b1b16cc6b2d1c4ec557e5eb96f09335f066",
ip: "::",
listenAddr: "[::]:30312",
name: "Geth/PrivateChain1/v1.8.7-stable-66432f38/linux-amd64/go1.10",
ports: {
discovery: 30312,
listener: 30312
},
protocols: {
eth: {
config: {
byzantiumBlock: 0,
chainId: 193,
eip150Hash: "0x0000000000000000000000000000000000000000000000000000000000000000",
eip155Block: 0,
eip158Block: 0,
homesteadBlock: 0
},
difficulty: 4595264,
genesis: "0xf6e5dec52d779d6f64e2962f4a60fb5e7072fc6d15935cf7425278b7784016f9",
head: "0x5a26608afb28b4418c23d808f1df35a8f0baff0f193dcba3d102c25f83d84fe3",
network: 1902
}
}
}
From node2:
To add node 1 in peer list of node 2, you need to pass enode info of node1 in addPerr function. Replace [::] with IP of node 1. Use localhost if running both nodes on same machine.
admin.addPeer("enode://3414c01c19aa75a34f2dbd2f8d0898dc79d6b219ad77f8155abf1a287ce2ba60f14998a3a98c0cf14915eabfdacf914a92b27a01769de18fa2d049dbf4c17694@:30301");
Then you can access smart contracts of node1 from node2.

Here I use a private bootnode for each node discovery on the network1. Is there a need to pass enode info of node1 to node2 of the external network?– ludoDec 20, 2018 at 8:52
