Prevents direct peer-to-peer interactions between devices
The VPN won’t fix the core issue of opening ports to the Internet correctly—it might even complicate things further. I chose to leave PIA behind since it only permits one port, which is rarely practical for most situations. Games tend to select multiple ports, often requiring different ones.
In summary, the best approach would be to turn off UPnP, remove all ports you created, and set up a DMZ. Since your device is a Technicolor TC7200 router, let me know if this helps. Thank you for your assistance!
Avoid setting up a DMZ on your home network. Use another router on the same network if possible; if that resolves the issue, your current router might be faulty. If the problem persists with another router, it could indicate an issue with your local ISP or a higher-level blockage.
