Not sure how serious this is, but Apache seems to be allowing the REMOTE_ADDR variable to be changed, somehow. I've tested this under Debian, MacOSX, and FreeBSD, so it doesn't seem to be OS dependent. I've tried setting a custom variable to REMOTE_ADDR using mod_rewrite, and the custom variable still gets the wrong address. IIS seems to handle the same sort of mangling - whatever's getting done (tcpdump tells me nothing) just fine. The correct IP address is getting sent to the log file. http://beta.active-forums.com/test.php Will output the $_SERVER['REMOTE_ADDR'] variable via php If you put the same address in at http://proxify.com, it will instead report a 10.x address (obviously nonsense) when the real address is usually a 67.x Thanks in advance for any help. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
