when you use proxy, it will read on the login as the proxy ip, similar to vpn. but inorder to check that the proxy is working as intended you need to check from login > char > map, the best way to do it is try logging in to login server and check the ip connected to the login port, then proceed to char ip, then check again on the char server if proxy ip is connected to the char server port as well as the map server, this is one way to ensure that proxy is working properly, otherwise it will only read the proxy ip on the login server, but then uses players ip when connecting to char and map.
