Need to do port forwarding!

I have a laptop and my YU Yureka with internet access.

I need to use internet on my laptop from my phone.

Now, there are a few applications on my laptop that need port forwarding to work.

How can I forward some ports so that my applications work using mobile internet only?

Please do keep in mind that I do not have access to a modem or a router, just my phone.

Thanks in advance.
