Description of problem: In some special cases it is necessary to make the origin servers to see the client's IP address when going through Squid. This is already possible with this kernel patch: http://www.balabit.hu/en/downloads/tproxy/ I would very much like to see that provided with the stock RH-kernel.
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
