Changing ports isn’t a terrible thing, also not the perfect “fix” either, as you can still recognize open ports and scan the service on them.
Some ports are reserved in networking, so should stay away from those.
Some ISPs don’t allow you open ports on 80/443 as those are web hosting ports and they provide a service to consumers to download content from the internet, not for their consumer to be a web hosting provider as well. That’s at the residential level, if you have a business plan that might change, but it might be hard to convince and ISP otherwise.
Still love the GameCube and games. This is what we introduced the kids too and it’s been fun watching them play the games that brought me a lot of fun too.
Mario Kart
Super smash brothers
Crazy Taxi
Could find the RCA connections on tvs now, but the Wii was great in the backward compatibility! Dolphin worked great for some games too, and a controller USB adapter and we’re in business!
