I would not do it like that. <br>
Better is to use something like Hitch or HaProxy (my preference) and
put that in front of Varnish. <br>
Then HaProxy / Hitch can terminate all SSL traffic, and HaProxy can
also do your redirect to SSL if needed. <br>
Then in Varnish you use the Apache server as a backend and let it
only serve what it needs to serve.<br>
Use the ProxyProtocol to send the client information from HaProxy to
Vernish.<br>
In Varnish you need to put the client IP into the X-Forwarded-For
header.<br>
In Apache you can then use this header to have the real client IP
address.<br>
<br>
This way you have the real client IP information on all layers.<br>

<p>I'm running varnish in front of my apache on port 80 without
any issues so far.<br>
<br>
Recently I decided to also use varnish for SSL connections<br>
<br>
To do so I first do a http to https redirect within varnish VCL<br>
<br>
if ( req.http.X-Forwarded-Proto !~ "(?i)https" ) {<br>
return (synth(750, ""));<br>
}<br>
<br>
then in vcl_synth()<br>
<br>
sub vcl_synth {<br>
<br>
if (resp.status == 750) {<br>
set resp.status = 301;<br>
set resp.http.Location = <a class="m_-2053081272555223348moz-txt-link-rfc2396E">"https://"</a> + req.http.host +
req.url;<br>
return(deliver);<br>
}<br>
}<br>
<br>
This works fine and all http got redirected to https<br>
<br>
Then on port 443 I got apache listening as a reverse proxy with
the following config:<br>
<br>
<VirtualHost *:443><br>
<br>
ServerName <a href="http://somedomain.com" target="_blank">somedomain.com</a><br>
ServerAlias *.<a href="http://somedomain.org" target="_blank">somedomain.org</a><br>
<br>
SSLEngine on</p>
<p> ... ssl cert stuff here ...<br>
</p>
ProxyPreserveHost On<br>
ProxyPass / <a class="m_-2053081272555223348moz-txt-link-freetext" href="http://127.0.0.1:80/" target="_blank">http://127.0.0.1:80/</a><br>
ProxyPassReverse / <a class="m_-2053081272555223348moz-txt-link-freetext" href="http://127.0.0.1:80/" target="_blank">http://127.0.0.1:80/</a><br>
RequestHeader set X-Forwarded-Port "443"<br>
RequestHeader set X-Forwarded-Proto "https"<br>
<p></VirtualHost><br>
<br>
Also this works perfectly fine! Apache does the SSL termination
and then reverse proxies everything back to varnish on port 80<br>
<br>
If I have a look in the apache ssl log:<br>
<br>
[15/Aug/2017:02:03:41 +0200] 35.190.201.122 TLSv1.2

<br>
If I look in the varnishlog I see the following:<br>
<br>
<a href="http://domain.org" target="_blank">domain.org</a> 35.190.201.122 - - [15/Aug/2017:02:03:41 +0200] "GET

301 0 "-" "Go-http-client/1.1"<br>

"Go-http-client/1.1"<br>
<br>
But in the process of Varnish -> Redirect http to https ->
Apache Reverse Proxy -> Varnish I loose the client IP address
in varnishlog<br>
It jsut says 127.0.0.1<br>
<br>
How can I forward the client IP to varnishlog in this process?<br>
<br>
I need to have the client IP in varnishlog as I use those to
generate statistics about the website.<br>
<br>
any help, hints or insights would be awesome ;)<br>
<br>
Thanks & greetings<br>
Becki<br>
