Set up port forwarding for your new router.
Set up port forwarding for your new router.
Hey everyone, I've been running a Minecraft server for a few years with friends, but after my family installed a new router, I'm having trouble getting port forwarding to function. My router is an Asus RT-AX92U. I've tried several approaches: using the "Open NAT" settings on the router, configuring it via the "WAN" settings, setting a static IP and enabling UPNP, applying Windows Defender rules, updating the router, and even switching from Ethernet to WiFi. I ran tracert and checked if ports like 5000:5001 are open. This is how I set up the forwarding on the new device. Before you ask, I know these aren't my public IPs—I've been using canyouseeme.org to verify the ports work and confirm with ipconfig.
Configure a single port forward rule linking 192.168.1.22 and 192.168.1.222. Assign one static IP to each device and disable the forwarding for the other. Verify whether the new router is replacing the old one or simply adding functionality. Ensure no double NAT is applied and that both protocols remain compatible.
I usually connect via Ethernet, but I only configured the second rule for testing on WiFi. When I tried using 0.0.0.0 as the source IP, it didn’t work either. The new router has completely replaced the old one, and the modem remains unchanged.
LAN operates correctly, and I can access the server without delay. It doesn’t appear to be the 25565 port that’s preventing connections, as all other ports I’ve tested also fail to open.
You mentioned concerns about Java and firewall settings. It seems you're trying to allow specific ports like 25565 and 8080 without blocking them. Also, you noted a server was previously on your PC, which might affect the setup.
