My local machine does not have a public IP and the IT department cannot setup an NAT for me, I want to setup a proxy on my remote public server which will forward the request to my local server.

I try using privoxy + ssh, but it says invalid header.

Step 1:
open a ssh tunel by

ssh -nNT -R 8081:localhost:8080 user@example.com

Step 2:
On the remote machine, configure a privoxy config, I tried

forward-socks5 / 127.0.0.1:8081 .

listen-address 0.0.0.0:8080

and

forward / 127.0.0.1:8081

listen-address 0.0.0.0:8080

both said invalid header in browser

After some investigation, I found the reason:

Privoxy is not suitable for such an reverse proxy job,
and ssh forward can only accept local traffic.

So there are 2 approaches for solving this problem:

1. setup iptables rule for tcp forwarding (I'm not professional on this, but I think it's possible)




2. setup a reverse proxy forwarding request to ssh forwarding port, this can be done through nginx, or write a simple one by oneself, for example, using go:

e.g.

package main

import (

    "net/http/httputil"

    "net/http"

    "net/url"

    "log"

)



func main() {

    target, _ := url.Parse("http://localhost:8081")

    proxy := httputil.NewSingleHostReverseProxy(target);

    http.Handle("/", proxy)

    log.Fatal(http.ListenAndServe(":8080", nil))

}
