Http tunneling can be used to bypass port routing or uPnP?

Question

I am currently working on an application and I would like to know if http tunneling can be used to bypass port routing or uPnP? If so, how can this be done and do I need an external server to transfer information to it?

I am coding in C ++, so I would appreciate it if the answers concerned this working language. If not, this is normal, because I can redo the C ++ code if possible.

Thanks.

Here you will get an explanation of how it works. Then you will find a lot of code and libraries on punching holes in firewalls . See below.
