I’m using an old program that doesn’t automatically forward ports. I’ve experimented with using the same ports as another program, but it didn’t yield the desired results. Manually opening the ports directly in the router did not resolve the issue. I also tried a port forwarder, and it works but only intermittently.

If you have any recommendations for programs or tools that can reliably forward TCP and UDP ports via UPnP, please share them with me. I’m looking for a solution that is user-friendly, and works consistently.
