[ALUG] SSH tunnelling

I need to access the web server on a VM in my office, from my laptop. I have SSH access to an intermediate PC and from there to the VM. Ie: Laptop -> PC -> VM How do I set up a tunnel from laptop through PC to VM to give me access to port 80 on the VM? If relevant: Each of the two SSh connections will require (different) user/password.
