As I explain in the title..

I am trying to use a VPS that connects to my real secret server IP, this can be done easy with iptables but I lose the client IP and this is big problem, I would like to be able to forward the client IP to the server.

Any idea what I should use? The VPS is Linux based and Server is Windows.

I am so confused, tried everything but I have no idea... haproxy, nginx, squid...

What is the easiest option to achieve this? I forward clean traffic, Not encrypted.. but its not 80 port, its other ports

I don't use HTTP

why not? some claim its possible..

    It is usual for the reverse proxy to set a header (e.g. X-Forwarded-For) which the upstream service uses to determine the real client IP address. – Richard Smith May 16 at 10:29
  • Can you help me more detailed? what I should use and how? – user1539889 May 16 at 10:36
  • This question is quite vague. What exactly is this traffic that you trying to "forward"? Why don't you just use a hosting provider that includes DDoS protection? – Michael Hampton May 16 at 18:18

If you do it with iptables - IP address will be lost. If you are using http/https protocol - you can setup proxy server to add additional headers with IP address.

an example is here: https://www.nginx.com/resources/wiki/start/topics/examples/forwarded/

you can do it on any port as long as it is http traffic

  • I don't use HTTP, sorry, is that I problem? I think its telnet Can you help me? – user1539889 May 16 at 13:10
  • probably you will not be able to capture client ip on the destination server – Martynas Saint May 16 at 13:21
  • Eh.. it should be possible, that's why I am here to ask... – user1539889 May 16 at 15:07
