There are a couple of "not yet officially supported" functions in the module ssh_connection named direct_tcpip and tcpip_forward. We are using the first one to set up a ssh tunnel in a project and so far we have not encountered any problem.

As far as I know, the OTP SSH client doesn't have any option that
would support this. However, you can open a connection using
ssh:connect, then pass along data that connection using the
ssh_connection module. So you should be able to implement a tunnel
over the OTP SSH client.
