It's not the same thing as a proxy, so the X-FORWARDED-FOR header will not be set by your router. There is no way to get your internal NATed IP address from a request to a server. My code doesn't display the IP on a page, it modifies the IP address within the scope of an ATG servlet pipeline. You should be able to make it write to file pretty easily, but I don't have the time right now to do that for you. If you're using Apache it would probably be much simpler to just add the X-FORWARDED-FOR header to the Apache log format, similarly to this: %{X-Forwarded-For}i %l %u %t "%r" %>s %b "%{Referer}i" "%{User-agent}i" @John: if you’re being a router at home, it’s providing NAT (network address translation) so that all your computers at home only use a single real-world routable IP address.

Is there a way to display my real IP even when using a router? Also, is it asking too much for you to edit your Java code and recompile a class that automatically prints the IP to a text file instead of displaying it on the webpage? I am in the process of tracking down a scammer and need some Java code that records every IP address to a text file located on the server. Any help / suggestions would be greatly appreciated!

Do you know of a Wordpress plugin for that you'd recommend? I googled and found several, but would love a recommendation. Honestly, because I don’t use social bookmarking sites myself.

I'm definitely bookmarking this. I’m curious why you don’t enable social bookmarking/digging/etc. on your blog entries. I’m definitely bookmarking this.
