After hours and hours of testing, I found the way to get your Public IP address from a php script located in your server, which echoes your IP, finally I am close to release my game!
dbpro code:
#constant SERVER_NAME "xx.xxx.xxx.xx" rem put your server ip here
global IPAddress as dword
global Connection as dword
global ReturnStr as string
global yourPublicIP$
RequestPublicIP()
print yourPublicIP$
wait key
end
rem function Abort()
function Abort(Msg as string)
print "Error : "; Msg
print "Error : ("; SOCKET ERROR(); ") "; SOCKET ERROR$()
wait key
end
endfunction
rem function RequestPublicIP()
function RequestPublicIP()
messageGet$= "GET http://vpsaddress.net/GetIP.php" rem change the address to your server's address and make sure your script is called GetIP.php, if you change the name of the script change it here too
IPAddress = HOSTNAME TO IP( SERVER_NAME )
if IPAddress = 0 then Abort("Unable to determine the IP address")
Connection = NEW CONNECT SOCKET( IPAddress, 80)
if Connection = 0
Abort("Unable to get a connection to the server")
endif
if SEND SOCKET STRING( Connection, messageGet$ ) <= 0
Abort("Unable to transmit")
endif
SHUTDOWN SOCKET SEND Connection
ReturnStr = RECV SOCKET STRING$( Connection )
if SOCKET ERROR() > 0
Abort("Unable to receive")
endif
yourPublicIP$= ReturnStr
DELETE SOCKET Connection
endfunction
Inside the GetIP.php script:
<?php
$output= get_ip_address();
echo $output;
// client IP
function get_ip_address() {
// check for shared internet/ISP IP
if (!empty($_SERVER['HTTP_CLIENT_IP']) && validate_ip($_SERVER['HTTP_CLIENT_IP'])) {
return $_SERVER['HTTP_CLIENT_IP'];
}
// check for IPs passing through proxies
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
// check if multiple ips exist in var
if (strpos($_SERVER['HTTP_X_FORWARDED_FOR'], ',') !== false) {
$iplist = explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']);
foreach ($iplist as $ip) {
if (validate_ip($ip))
return $ip;
}
} else {
if (validate_ip($_SERVER['HTTP_X_FORWARDED_FOR']))
return $_SERVER['HTTP_X_FORWARDED_FOR'];
}
}
if (!empty($_SERVER['HTTP_X_FORWARDED']) && validate_ip($_SERVER['HTTP_X_FORWARDED']))
return $_SERVER['HTTP_X_FORWARDED'];
if (!empty($_SERVER['HTTP_X_CLUSTER_CLIENT_IP']) && validate_ip($_SERVER['HTTP_X_CLUSTER_CLIENT_IP']))
return $_SERVER['HTTP_X_CLUSTER_CLIENT_IP'];
if (!empty($_SERVER['HTTP_FORWARDED_FOR']) && validate_ip($_SERVER['HTTP_FORWARDED_FOR']))
return $_SERVER['HTTP_FORWARDED_FOR'];
if (!empty($_SERVER['HTTP_FORWARDED']) && validate_ip($_SERVER['HTTP_FORWARDED']))
return $_SERVER['HTTP_FORWARDED'];
// return unreliable ip since all else failed
return $_SERVER['REMOTE_ADDR'];
}
/**
* Ensures an ip address is both a valid IP and does not fall within
* a private network range.
*/
function validate_ip($ip) {
if (strtolower($ip) === 'unknown')
return false;
// generate ipv4 network address
$ip = ip2long($ip);
// if the ip is set and not equivalent to 255.255.255.255
if ($ip !== false && $ip !== -1) {
// make sure to get unsigned long representation of ip
// due to discrepancies between 32 and 64 bit OSes and
// signed numbers (ints default to signed in PHP)
$ip = sprintf('%u', $ip);
// do private network range checking
if ($ip >= 0 && $ip <= 50331647) return false;
if ($ip >= 167772160 && $ip <= 184549375) return false;
if ($ip >= 2130706432 && $ip <= 2147483647) return false;
if ($ip >= 2851995648 && $ip <= 2852061183) return false;
if ($ip >= 2886729728 && $ip <= 2887778303) return false;
if ($ip >= 3221225984 && $ip <= 3221226239) return false;
if ($ip >= 3232235520 && $ip <= 3232301055) return false;
if ($ip >= 4294967040) return false;
}
return true;
}

I have edited some variables and functions name from italian to english, so that everyone will understand better the code, I hope I didn't make any mistake by doing this.
