You could also create an ssh-tunnel if you are behind a firewall to
establish a private connection to the target system (which at the time
you have performed a uni-directional call, means that you most likely
can establish also an ssh-tunnel).

It would be also possible to create a bidirectional tcp-based channel
that does the same: provides a tunnel where bi-directional traffic can

This is relatively simple, and should be a good exercise for those of
you pondering doing a fun project.
