<p class="MsoNormal" style="margin-bottom:12.0pt">Ray,<br>
<br>
ZendTo already supports the X-Forwarded-For header.<br>
<br>
Our setup at the University of Southampton is also behind an F5, and it all works fine.<br>
I haven't installed any extra Apache modules to make it work.<br>
<br>
The only problem we had was when our enterprise IT folks hadn't enabled the X-Forwarded-For header on the F5 config that was for the ZendTo service (dropoff.soton.ac.uk).<br>
<br>
Are you using the latest version of ZendTo?<br>
<br>
Cheers,<br>
Jules.<o:p></o:p></p>

<p class="MsoNormal">“Rpaf changes the remote address of the client visible to other Apache modules when two conditions are satisfied. First condition is that the remote client is actually a proxy that is defined in module configuration. Secondly if there is
an incoming X-Forwarded-For header and the proxy is in it's list of known proxies it takes the last IP from the incoming X-Forwarded-For header and changes the remote address of the client in the request structure.”<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Access to our zendto installation is behind an F5 load-balancing proxy. The affect of this is that the IP addresses of client access all look to come from the IP address associated
with the proxy rather than the actual IP address of the client machines. The proxy address is what is captured in the zendto database and is included in the reports which zendto sends out. For security it would be useful to see the client IP addresses.
The Apache server can be configured to log this as an x-forwarded-for address<o:p></o:p></p>
