Problem with redirecting traffic on AT&T BGW320-500 devices
For reference, I own an AT&Ts fiber router and have added the ports to make it accessible. Despite this, the port remains closed regardless of my actions. After restarting the router and frequently adjusting my firewall settings, it still doesn’t appear as open. On the AT&T website configurator, using the router’s IP address, it is listed as available—but the port isn’t actually open.
Which ports are involved? Where should they be sent? Make sure the internal IP is accurate. Verify if something is listening on that port on the destination machine. Test connectivity to that port from another device in your network. Ensure your router's WAN address is a public IP, avoiding private ranges like 100.64.0.0–100.127.255.255.
AT&T doesn't apply CGNAT to their residential fiber internet packages, which I've verified through my own experience. It's likely the issue lies elsewhere—perhaps the device itself isn't responding or a firewall is preventing the connection.
To set up port forwarding, you require several components. The target device’s IP address must be static or reserved on the router’s DHCP server to remain consistent. It’s important to identify which ports need forwarding. You also need the protocol—such as TCP, UDP, or both—and confirmation that the desired service is active. Additionally, be aware that certain ports may be restricted by ISPs due to security concerns.
The port is set to use the device name or router label. I chose the relevant PC and confirmed both UDP and TCP are enabled, but the Minecraft server still can't open the port.
