SSH Tunneling or SSH port forwarding is typically useful if you have a network with a private segment like this:
-----------------------------------------------------------
| |
| |
--------- ----------- -------------- |
|localhost|------------------------------| gateway |------------------| hidden | |
--------- | 10.2.2.18 | | 172.16.0.42 | |

-----------------------------------------------------------
On localhost forward port 2222 to hidden's port 22:
ssh -L 2222:172.16.0.42:22 gateway
Then you can e.g. scp from localhost to hidden by using localhost's port 2222:
scp -P 2222 file1 localhost:
