request.remote_addr in current setup does not report ip address of requester

[robvandijk]

We use request.remote_addr to locate the requester and center the map.

However, due to nginx proxying, request.remote_addr now contains the ip address of the docker_nginx-load-balancer network.

[robvandijk]

When using curl -4 https://waarismijnstemlokaal.nl my real IP address is shown, when using -6 not.

So, any connections on Ipv4 get their correct address into Flask. Any Ipv6 connections coming in gets the Ipv4 address of the docker interface passed to Flask.

[robvandijk]

For this we had to add an ipv6 network to nginx-load-balancer.
