client IP address incorrect. How to set x-forwarded-for in Varnish 4?

[kindnation]

When I use this Varnish default.vcl, it shows my nginx webserver's IP for the client's IP address. Can you add the X-Forwarded-For and client.ip so that Varnish sends the correct client IP?

Add these lines in your /etc/nginx/nginx.conf :

set_real_ip_from   127.0.0.1; #Put the Ip of your varnish/proxy here
real_ip_header      X-Forwarded-For; #Put the Header that your varnish/proxy set

Oyabi,

I already have that in my nginx.conf. I also have CloudFlare and have added all their proxies to the set_real_ip_from. The client's IP information is correct when I remove Varnish, and send from CloudFlare directly to Nginx. Only when I add Varnish, it seems that it is removing the X-Forwarded-For for the client's IP.

I doesn't use CloudFare so it's will be difficult for me.
Have you try this ? https://support.cloudflare.com/hc/en-us/articles/200169376-Can-I-use-CloudFlare-and-Varnish-together-

Tell me if one of these solution works for you. =)

Hi Kindnation,
for cloudflare add following to your nginx.conf

set_real_ip_from 127.0.0.1; #Put the Ip of your varnish/proxy here
real_ip_header CF-Connecting-IP;

This will then restore correct visitor ip in nginx logs.
