Note Submitter: shane at 007Marketing ---- I am just starting to try to tackle this issue of getting the real ip address. One flaw I see in the preceding notes is that none will bring up a true live ip address when the first proxy is behind a nat router/firewall. I am about to try and nut this out but from the data I see so far the true ip address (live ip of the nat router) is included in $_SERVER['HTTP_CACHE_CONTROL'] as bypass-client=xx.xx.xx.xx $_SERVER['HTTP_X_FORWARDED_FOR'] contains the proxy behind the nat router. $_SERVER['REMOTE_ADDR'] is the isp proxy (from what I read this can be a list of proxies if you go through more than one) I am not sure if bypass-client holds true when you get routed through several proxies along the way.
