Thanks again. That article is very clear.
The piece of software you suggest (which I think is called Entunnel, not Etunnel) is not freeware.
I first tested this with "SSH Tunnel Client 3.0" which is free for personal use. Available on many download sites, publisher's page seems to be:
http://www.delight.ch/ (but it's in German). This works just as you described.
I then snooped arround some more and found out you can also achieve this with Putty. It is simple and I used this guide to set it up:

My management host is a linux machine and already has an sshd running. Tomorrow at work I will test this "for real" since at the moment that host is not allowed as a GUI client on the firewall. I tested this at home with a tunnel to some other application and it works fine, so I'm confident it'll turn out ok tomorrow too.
