I made a Server via Sockets with the port 5902. The client can connect, but only if I forward the port on the router. Is there a (simple) way (with a library?) to create a tunnel through port 80? Because somebody told me I should do this but I don't know how to.
P.S. I don't want that a library creates the 5902 socket and for example writes all recieved data in a file or in the console, I want (if it's possible) that I have my Socket and get all data there.
