Setting up port forwarding can disrupt your internet connection.
Setting up port forwarding can disrupt your internet connection.
ISP may add extra fees for static IP and port forwarding... Check if the ports you're attempting to use are open. https://ping.eu/port-chk/
I consulted my ISP who confirmed there are no restrictions on any ports, everything seems fine from their side. I have two SSIDS—one using 5G and the other 2.4G. Since I don’t have guest networks, my router is configured with Google DNS servers (8.8.8.8). There are no QOS optimizations applied. I have an IP reservation for my PC (which hosts Sven Coop) and my phone, and IPv6 is enabled. I just realized my router might be set to the wrong timezone, which could be the issue.
I've observed that computers often react negatively when they're not synchronized with nearby devices. You can try resolving that issue. Have you confirmed the IP reservation?
You're looking for reasons why Internet access might be interrupted when using port forwarding. It could depend on which ports are open or blocked, so checking those is key.
Absolutely, this situation should never occur. Even when you restrict all ports to one device, NAT for the rest of the LAN remains unaffected. The only scenario where it might fail is with advanced forwarding techniques that capture all traffic from the LAN to a port and reroute it—though I’m not aware of consumer routers that handle this.
