$_SERVER['SERVER_ADDR'] returns *NAT* address

[dmcole]

I have a server on a local area network that interfaces to the public network through NAT. When I query the variable $_SERVER['SERVER_ADDR'], it returns the LAN address, not the public address.

 

My question: Does anybody know how to get the public IP address in PHP?

 

Thanks.

$_SERVER['REMOTE_ADDR']

ignace is referring to the client's address.. if PHP is getting the subnet ip of the computer the server is running on, you most likely cannot reference the ip of the network it is running on without jumping through a loop or two.. like set up some free webhost on freehostia.com or whatever than set up a php file that spits out the 'REMOTE_ADDR' server variable and then file_get_contents on that file to get the ip address assigned to your network not your computer ON the network..
