I've been trying this for a long time and I have not yet found a good solution. I have several servers behind a NAT that all run an SSH daemon. One of the machines is my main server which gets the SSH port forwarded to it. What I want is basically open a connection to other NATed servers by going through the main server similar to what I can achieve by opening a connection to the main server and then SSHing in to the destination. Since there are some applications that run on top of SSH I'd like to make automate this in order to run rsync or git on top of the connection itself.
Is there a reverse proxy for SSH?
