Setting the network interface for core?

Question

it is possible to set the network interface that Core is using? Suppose my host has multiple interfaces, which one is selected?

Answer 1

As far as I see it binds to any IPv4 address on the specified PEER_PORT and there is no config option.

Same goes for the HTTP command interface, which is either any (if PUBLIC_HTTP_PORT) or just 127.0.0.1.
