ISP change now affects port forwarding for specific games.
ISP change now affects port forwarding for specific games.
Initially I connected the server straight to the ISP modem/router while the Asus router managed the rest of the house. I reset both devices and set up port forwarding through the ISP modem, disabled Wi-Fi, and tested various games—Port Forwarding worked fine for Valheim, Minecraft, and Project Zomboid, but not for Nephews. It seems the ISP modem doesn’t support bridge mode port forwarding. I’ll check for any overlooked settings or possible double NAT issues. I’m confident this is resolved now; everything functions as expected. I’ll continue improving it and share more solutions later. Thanks for your advice!
