FYI: "siblings" are proxies that fetch hits from each other. The proxy<br>
"going to the parent" is usually called a "child" proxy:<br>
<br>
clients -> child -> parent -> servers<br>

<br>
No, it will not (by default) AFAICT. For the parent proxy logs to<br>
contain IP addresses of the clients,<br>
<br>
a) The child proxy must send the X-Forwarded-For header to the parent.<br>
b) The parent proxy must trust X-Forwarded-For received from the child<br>
(as far as logging is concerned).<br>
<br>
Your configuration changes at the child proxy do neither (a) nor (b).<br>
<br>
IIRC, (a) will happen by default, while (b) requires<br>
follow_x_forwarded_for and log_uses_indirect_client rules at the parent<br>
proxy.<br>
<br>
I did not review your follow_x_forwarded_for rules.<br>
<br>
The follow_x_forwarded_for rules at the child proxy are needed if and<br>
only if you want the child proxy to trust the X-Forwarded-For headers<br>
received by that child proxy (from its clients). That is only necessary<br>
in deeper hierarchies:<br>
<br>
clients -> child1 -> child2 -> parent<br>
