I want Bitcoin Core to connect to Internet through TOR network.
I have some options in network settings tab:
1) Map port using UPnP
2) Allow incoming connections
[..]
Also, i want to ask you about 1st and 2nd option. For what purpose they are?
Do i need to disable incoming connections for maximum security?
Thank you so much!
To answer the remaining question, (1) allows your client to talk to your network device(s) such as gateway router/modem on how to clear a path for the data (identify one another and agree on connection settings like ports) without you having to manually configure them.
(2) Allows your node to support the network fully by allowing other nodes to initiate connections to it.
