REMOTE_ADDR Weirdness

[Phil Mattison]

But I'm not seeing the address of eth0. I have a separate eth0:n for each
vHost. The REMOTE_ADDR I'm seeing is the correct one for the vHost, but not
for the remote vHost.

Here are the scripts if you're just dying to see for yourself:

test.php
--------
<?
echo "<pre>";
while(list($k,$v) = each($HTTP_SERVER_VARS))
{
 echo "[".$k."] = ".$v."\n";
}
echo "</pre>";
?>

testq.php
----------
<?
echo "<pre>";
if(!$q)exit();
echo $q."\n";
$fp = fopen($q, "r");
if($fp)
{
 $response = "";
 while(!feof($fp))$response .= fgets($fp, 96);
 fclose($fp);
}
echo $response;
echo "</pre>";
?>

Use them like this:
http://vhostA/testq.php?q=http://vHostB/test.php

Yes, auto routing by linux. Go out the most direct route, short of
calling 127.0.0.1. I have a similar setup and if I don't go out to the
router from eth0 first, it'll go out on eth0:0 to eth:0's address.
