How to setup SSH tunneling in dropbear?

[Noor Maszuari]

Hi,
I'm newbie in dropbear and I would like to know how to setup SSH tunneling
using dropbear?
What if I use private key that is generated by PuTTYgen and the location of
the private key is /home/abc/xyz/pk.ppk?
How is my command line looks like?
