It would be very strange for something like that to exist. The ISP would prefer that nobody have any form of port forwarding because corrupted machines cause issues for everyone. Many even block port 80 and 443 to prevent people from running web servers in their house.
Port forwarding is pretty stupid so it is also easy to break it. All you really have to do is change the ip on your pc to something else. Port forwarding is a fixed rule that send the traffic to a particular IP address so all you do is chose a different one.
