This is a paid version of SSH Autotunnel with better and faster support. There are also additional features in this version:

----------------------
SSH Autotunnel is a simple, intuitive SSH tunneling application with automatic reconnection after internet connectivity problems and with automatic start up after the device is turned on.

This application can create secure tunnels using a SSH connection for the user to access services available only from the target machine. For example user can connect to the company server and then use web browser to connect to internal web site of their company, use remote desktop to connect remotely to their office PC desktop and control it from their Android device, or bypass a firewall restriction in their hotel or company by connecting to Internet pages from the remote machine.

The application uses standard SSH protocol, without the need to configure and setup a VPN. The only information the user needs to know is the login information to the remote machine and IP/port information of the service they want to connect to. Once the SSH tunnel has been established, the user can connect to the specified local port to access the network service on the remote side using the same application they normally use when their device is connected to that network. The local port need not have the same port number as the remote port.

Ssh Autotunnel is using JSch and Bouncycastle projects, which are under BSD and MIT licenses

USER GUIDE:

You put public address of as a server that is entry point to the intranet. Use username@ip[:port] (you can use hostname instead of ip of course and you can use different port than 22). Then use either password or ssh key (or both in which case ssh key is expected to be encrypted with the given password). Then on the menu you can add forwardings. You can have as much forwarding for one connection as you want. You need to specify local port, host and remote port. You can also select if this is local or remote forwarding. See https://en.wikipedia.org/wiki/Port_forwarding for more details on port forwarding. Also note that this application doesn't support any kind of SOCKS proxy.

The application supports both types of private keys - those generated by putty's keygen (ppk) and also the open ssh keys (Linux format). Just copy/paste the content of the key file to the appropriate text box or enter path to the file location on the Android device (e.g. /sdcard/id_rsa.pub). If you experience connection issues and are sure your password is correct, try reexporting your key using a certified tool (such as puttygen) and use the exported key with SSH Autotunnel since some tools do not generate proper OpenSSH format keys.
Also check with your ssh server administrator about server logs.
