trusted proxies and real ip

[norkunas]

currently in compose.yaml there is:

TRUSTED_PROXIES: ${TRUSTED_PROXIES:-127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16}
TRUSTED_HOSTS: ^${SERVER_NAME:-example\.com|localhost}|php$$

ok so spin up for the localhost, my container has this:

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' www-php-1
172.21.0.1

but for some reason in Symfony $request->getClientIps() returns the container ip. what more configuration is needed?
