How to Port Forward Without Router Access | 2021!

This is an updated video of one I did a while ago. This process uses third-party software, so I am not responsible for any damage or crashes that could occur to your router or modem. I'm also not responsible for any fines your ISP may give you for using this method (this isn't likely though).

Download Port Mapper 2.1.1 (the only working version for me):

If this worked for you, be sure to subscribe and like the video!

Check out my new website that features my latest action top-down shooter, Breaking and Entering:

I got it connected, but when i used the port checker using a website it says its still closed, so i checked it on my routers panel, and I did all saw the UPnP mapper ports in it and active, but its still close using a port checker. So im guessing my ISP blocks it, 'cause i found some article for my ISP and peoples theory they say that it depends on your plan you picked in that ISP, if you bought the Home/Personal one, you won't be able to access more features(but ISP did not mention anything in their plan brochure) and if you bought the business one, you will be able to access features, and Business plan is much more expensive. In that case i can't port forward.

I'm getting an error stating I have to enter localhost manually, and now another error stating that it failed because it couldn't receive a response from the UPnP device. Why is this happening?
I have a eero router with eero secure enabled.
UPnP is on.

Edit: I realized it was because I typed in a remote host instead of leaving it blank.

This video ommits the super duper big IF that is if UPnP is enabled in the router. Normally ISPs that don't want to give router access, also don't leave UPnP enabled by default.
