We are using Nginx to terminate SSL and passing the requests to Varnish and then to Apache
We are getting invalid IP address from Nginx proxy_add_x_forwarded_for and remote_addr
Please find the Nginx settings as mentioned below:


FYI..
SSL is on port 443
Varnish is on port 80
Apache is on port 8080


Nginx Settings:
---------------------------
server {
listen *:443 ssl;
server_name *.website.com;

ssl on;
