Note that you can run one/both sides of a forwarding connection on a symbian mobile device. Very handy for running rsync to your mobile phone, getting at IMAP/SMTP email servers or using VNC over SSH.

I’ve even used this in the past to forward my home iTunes Daap access to my work system:

Georgi, thanks for your kind comments!

Stefano, you’re absolutely right, and I use the SOCKS proxy option myself quite often. Using an existing proxy is sometimes helpful if part of the object is to cache your fetched materials where you’ll be able to reach them later. As I mentioned, this article really just scratches the surface of port forwarding, but certainly there are people doing ingenious things out there with the capability! Keep the hints coming.

If you don’t need to really login on the machine, it’s better to use “-N” , so you won’t launch commands on the wrong machine by mistake.

Another interesting trick is the ability of ssh to make a SOCKS proxy. (-D option)
You don’t need an actual SOCKS proxy. Ssh and a (reachable!) server with internet access is all you need.
For example, if you are on a restricted network and need to get out, or perhaps you just need to reach some web administration tools on the “remote” LAN the server is connected to, just do.
ssh someserver -D 8080
and you’ll get on localhost:8080 a socks proxy.
if you want to share it with your friends in the LAN, you can by doing
ssh someserver -D 192.168.1.0:8080
assuming that 192.168.1.0 is the network address of your LAN.
