I have a question regarding restriction access to private etehreum network.
I created my Private Etehreum network using Geth(for now just only with one node) on the Ubuntu 16.04 virtual machine.
And I have the App which is communicated with private network by Web3, this app is hosted on the different virtual machine.
I ran my node from the console with this command:
geth --datadir=/ethereum-private/chaindata/ --rpcapi admin,personal,web3,eth,miner --networkid 11 --rpc --rpcaddr 0.0.0.0 --rpcport 8545 --rpccorsdomain "*"
And after that I'm able to connect by
geth attach http://220.127.116.11:8545 or throug web3
web3.setProvider(new web3.providers.HttpProvider(host)); from any server or computer.
So what I want to do it's to allow access to my ethereum network only for that server where my App is located and restrict it for any other servers/ips
Can you please tell me how can I do it?
