我有一个带有 PHP 的网页，我试图获取客户端 IP，但我得到的是服务器网关 IP 地址（192.168.0.1）。

这是我在办公室的：

ISP ---> ISP 路由器 ---> 我的路由器(192.168.0.1) ----> (192.168.0.2)我的服务器。

我尝试了所有这些行，但我无法获得真正的 ip，只有 SERVER GATEWAY ip。

$_SERVER['HTTP_X_FORWARDED_FOR']
$_SERVER['HTTP_CLIENT_IP']
$_SERVER['HTTP_X_REAL_IP']
$_SERVER['GATEWAY_INTERFACE']
$_SERVER['SERVER_ADDR']
$_SERVER['SERVER_NAME']
$_SERVER['SERVER_SOFTWARE']
$_SERVER['SERVER_PROTOCOL']
$_SERVER['REQUEST_METHOD']
$_SERVER['REQUEST_TIME']
$_SERVER['QUERY_STRING']
$_SERVER['DOCUMENT_ROOT']
$_SERVER['HTTP_ACCEPT']
$_SERVER['HTTP_ACCEPT_CHARSET']
$_SERVER['HTTP_ACCEPT_ENCODING']
$_SERVER['HTTP_ACCEPT_LANGUAGE']
$_SERVER['HTTP_CONNECTION']
$_SERVER['HTTP_HOST']
$_SERVER['HTTP_REFERER']
$_SERVER['HTTP_USER_AGENT']
$_SERVER['HTTPS']
$_SERVER['REMOTE_ADDR']
$_SERVER['REMOTE_HOST']
$_SERVER['REMOTE_PORT']
$_SERVER['SCRIPT_FILENAME']
$_SERVER['SERVER_ADMIN']
$_SERVER['SERVER_PORT'] 
$_SERVER['SERVER_SIGNATURE']
$_SERVER['PATH_TRANSLATED']
$_SERVER['SCRIPT_NAME']
$_SERVER['REQUEST_URI']
$_SERVER['PHP_AUTH_DIGEST']
$_SERVER['PHP_AUTH_USER'] 
$_SERVER['PHP_AUTH_PW']
$_SERVER['AUTH_TYPE']

以下变量是“未定义的”：

-HTTP_X_FORWARDED_FOR
-HTTP_CLIENT_IP
-HTTP_X_REAL_IP
-HTTPS
-REMOTE_HOST
-PATH_TRANSLATED
-PHP_AUTH_DIGEST
-PHP_AUTH_USER
-PHP_AUTH_PW
-AUTH_TYPE



编辑：尝试了“var_dump（$_SERVER）”并且找不到客户端IP地址：（

编辑2：我在谷歌上搜索了一下，我“找到了答案”。用户Martin Hohenberg说的是对的。在NAT过程中标头被破坏，因此我的服务器无法读取原始 IP 地址。目前，如果不将服务器移到前面，我不知道解决此问题的可行方法。

If you are making a request from the machine where the server is running, then $_SERVER['REMOTE_ADDR'] will obviously contain your own IP address, which is 192.168.0.1
