If you want to do it directly, you can use :

sudo ssh -L 10548: host2.homeip.net:548 email@hidden

It works fine too

And add -R if you do not want shell on the distant machine (eg : host1)

sudo ssh -R -L 10548: host2.homeip.net:548 email@hidden

You can use SSHTunnelManager to do all of this with GUI !!!
