conn.remove_ip is always 127.0.0.1

Precheck

I am running phoenix behind nginx proxy and setup according to the suggested configuration
as mention in the docs Phoenix behind proxy

Environment

• Elixir 1.3.3
• Phoenix 1.2.1
• NodeJS v5.12.0
• NPM version 3.3.4
• Operating system: Linux 4.8.0-1-amd64, Debian Jessie

Expected behavior

I have a controller code as below,

def create(conn, %{"scammer" => scammer_params}) do
    remote_ip = Enum.join(Tuple.to_list(conn.remote_ip), ".")`
end

Will return current user remote IP address

Actual behavior

Always return 127.0.0.1 every time.

We don't perform IP rewriting automatically because doing so without an actual proxy is a security risk. Here is a discussion with snippets and projects you could use: elixir-plug/plug#319
