Here is the server nf (Ubuntu):Ĭert = /etc/stunnel/ You can bypass any firewall that allows HTTPS traffic only by disguising your traffic using Stunnel.You can wrap arbitrary traffic from any local port, and send it encrypted with SSL over any other port.This allows the execution of an SSH command to localhost that ultimately connects to the remote server: Once the traffic reaches the stunnel server, it is decrypted and forwarded to the server's local port 22, the SSH service. This traffic will then be encrypted by Stunnel and sent out over the network, to the stunnel server on the remote machine, also listening for traffic and connections on port 8000. The stunnel client will route traffic from local port 2222 to local port 8000. I am trying to create an stunnel connection from client to server. ![]()
