I am attempting to use my Windows 10 desktop to play peer to peer games (p2p) like Borderlands 2 and Pit People. However, there is some setting causing my desktop to not be able to play p2p games without using hamachi or similar software. I know that it's a setting on this computer alone and not router/modem/ISP as my laptop works fine. I have tried disabling the firewall completely (didn't work), tried specifically opening ports in the firewall (didn't work), and tried restoring the default firewall rules as well. I have also undone the "Shut UP Windows 10" settings.
Let me know if any additional information is needed.
