Reverse Proxy problem

Hello,

this is what i see regarding reverse proxy:

(Mit Proxy: 77.119.131.203 – Ohne Proxy: 82.220.38.149 – Client IP anhand der aktuellen Konfiguration: 82.220.38.149)

77.119.131.203 is the visitor IP adresse and 82.220.38.149 is the ip of the server. It does not matter if i click “Server is behind a reverse proxy” or not – it always takes the wrong IP 82.220.38.149 instead of the correct visitor IP 77.119.131.203

How can i get Geoip Detection to detect the correct visitor ip?
