The code is quite old and I guess the new site is using a lot newer version of
PHP.

This seems to be part of a javascript, you could replace that with a usage of
header(). http://www.php.net/manual/en/function.header.php
If you use full ip's in the $iplist (xxx.yyy.zzz.qqq) then you could use
if(in_array($_SERVER['REMOTE_ADDR'],$iplist)) {
header("Location: http://www.google.com");
}
This is quite a lot shorter code to write and you don't have to mess with
javascript, which don't necessarily work the same way on all browsers.
