Due to limitations of TCP/IP server socket bind, you can do the following: - just use network.host to configure an IP address. This is the most common case.
- use network.bind_host to a single internal IP address and network.publish_host to a single external IP address on the same(!) network interface (also known as virtual IP address). ES uses the "bind all" address as a fall back if the bind fails. - use the "bind all" address = 0.0.0.0 (or IPv6 ::1) for network.host if you want to use different (=all) network interfaces you want ES to listen on The name "publish_host" is a bit unfortunate. This is not a second IP address on another interface.
