If I have an NGINX server at 1.1.1.1
and in the NGINX server you have the config that forwards on http traffic to 2.2.2.2
:
upstream 123 {
server 2.2.2.2;
}
server {
listen 80 default_server;
location / {
proxy_pass http://123;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
For an outsider who only knows the address 1.1.1.1
. Is it possible for them to find out that the IP address 2.2.2.2
is the one that it is redirected to?
