![]() ![]() Kill exiting instances of stunnel, then run it: Server Stunnel Config File output = /var/log/stunnel4/stunnel.logĬert = /etc/stunnel/ ![]() This will be a simple Python HTTP server listening on port 9998. The traffic is forwarded on the remote server to an HTTP server that is listening. The communications channel is duplex, so stunnel client and server can both send and receive information. The stunnel server will receive encrypted SSL traffic on port 8000. Stop any running instances of stunnel, then start stunnel: We want to configure stunnel to listen for traffic on port 9999, and make connections with another stunnel instance on port 8000.Ĭlient Stunnel Config File output = /var/log/stunnel4/stunnel.logĬert = /usr/local/etc/stunnel/ On the client machine, we will forward local traffic from port 9999 to port 8000, where stunnel will receive the traffic and encrypt it before sending it to the stunnel server. It will decrypt the traffic and forward the traffic on to a local HTTP server running on port 9998: python -m SimpleHTTPServer 9998 Client Setup Client Port Configuration The server will receive traffic on port 8000. We will forward that traffic on to the remote stunnel server listening on port 8000. On the client, traffic from port 9999 (http, from the browser) will be forwarded to port 8000 (stunnel). In particular, we want to have HTTP traffic on the stunnel client on port 9999 (e.g., the browser opening localhost:9999) pass through the encrypted tunnel and be forwarded to an HTTP server listening on the stunnel server machine. either something like Charles Proxy which you've tried or some SOCKS proxy.Our goal here is to have traffic between a client and a server pass through an encrypted tunnel, with each service happening on different ports. To defer the resolving of the URL to the target system you need to run a proxy there, i.e. Since the host header is set from the URL you would need to make sure that the request gets forwarded to the remote system and the browser is not trying to resolve the URL by itself, because otherwise it would try to connect to server on the machine where the browser is running. The server will see the connection coming from 127.0.0.1.ĮDIT: after lots of communication it is now clear that the aim is not to have the right source hostname es claimed and in the question and not the right Referer as claimed in a response but that the Host HTTP request header has the expected value 'localhost'. The client will get the original certificate from the server because the forwarding is done at the TCP level. What you need in your case is just a simple TCP forwarder which can be done with socat: socat TCP4-LISTEN:1988,fork TCP4:127.0.0.1:41952 This tool is not designed to create a gateway from SSL to SSL. STUNNEL HTTP SERVER CODEStunnel is a proxy designed to add TLS encryption functionality to existing clients and servers without any changes in the programs' code Stunnel is a program to create a gateway between non-SSL and SSL. Maybe I need client = yes? But I don't have any certificate, unless which I exported from Firefox on the site of the service My original question: * TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 Please note that this certificate is different, than it is on localhost:41952. I want to connect on "listen:1988" and redirect requests with stunnel to "localhost:41952" -> redirect current config: I have a little service which listen only on and checks source hostname (it must be localhost). ![]()
