Oh come on, now its just bad faith. It's not like all ports are being blocked by default, its only a few well known ones either for security, or because your service is not compatible with having a reverse DNS one your IP.
Understand that on a network of billions of devices, some limitations are to be put in place ...
You wanting to do what is being done with those port is
a) bad pratice
b) unsafe
c) not the right way to do it, whatever it is.
USE . A . GODDAMN . VPN ! 
YOU DONT GET TO BE A SERVICE PROVIDER ON A RESIDENTIAL SERVICE !
