Unable to receive connections to my hosted games unless I use Hamachi

To all/any that can help...

I have tried everything I could find on the internet to see if I could get FG to work without Hamachi. The reason being is that Hamachi was messing up a friend's computer connection to the internet so he had to uninstall it. I would rather not have him use a detrimental program to his computer in order to play, so I'm turning to the FG community in hopes you can assist me in my issue.

I have so far:
Port forwarded 1802 on my cable modem to the router I use to distribute wifi.
Port forwarded 1802 on my router to the computer on wifi that needs it open

I have so far tested:
Canyouseeme.org with just the ports forwarded - fail
Same with Windows Firewall off and Avast Free AV off - fail

Somehow, as I think that I've forwarded everything to the correct internal IPs, I cannot see my machine on the internet through port 1802. And no, I cannot connect straight to the router or cable modem as I'm upstairs and cannot run a line to it (so please don't suggest). If there's not a way to host via wifi then I guess I just wasted money, because I really want my friend to play, but I really hope that's not the case (because I bought a lot).

I am fairly computer savvy but I'm at a loss at this point. Any help is appreciated.

Thanks.

Send me a PM.
It looks like you are on the right path but just missing something small.

This was a small misconfiguration on the NAT of the incoming router - it ha 3 wan interfaces so just needed to get the right one setup with the NAT and everything else was all set already.
