Hi Guys,

Been scratching my head for a few hours now and wanted to see if anyone can help.

1) I have a load balancer with 6 servers in the back end.

2) The back end servers are Nginx and to get the real IP addresses of the visitors, all I have to do is the following in each Nginx install and I am able to get the real client IP address of each visitor.

set_real_ip_from 192.168.255.0/24; <-- to handle the load balancer IP
real_ip_header X-Forwarded-For;

3) Now I have installed Varnish in front of each Nginx running on 127.0.0.1 doing caching and for some reason now Nginx doesn't see the real client Ip addresses anymore coming from LoadBalancer --> Varnish --> Nginx

It's printing the following:

IP address:
192.168.255.9 <-- this should be the real client IP address and not the 192.168 (assuming the load balancer IP address is being printed)

More detailed host address:
192.168.255.9

Many thank if you can help.

Dave

Anyone?

Looks like mangling X_Forwarded_For may be a known issue in Varnish?

Not too sure.

Try:

set_real_ip_from 127.0.0.1;
real_ip_header X-Forwarded-For;

Works for me with Varnish in front of Nginx on the same server. No load balancer though.
