I'm working with Server running Ubuntu Server 14.04. I use Plink to request some reverse tunnels from a remote computer to the server.For some ports that works just fine, but for most ports it seems like the server refuses the request. It works for ports that are regularly used for this application like the VNC port 5900, the RDP port 3389, and the MySQL port.It also seems to work for 5901-5999. I would like to get the other ports working too, but I can't figure out why it refuses those forwarding requests. There are no custom rules in the IPtables and it is an almost clean install. If you need more info, please ask me.
SHH Tunneling only accepted on some ports
