The port forwarding issue isn't resolving. Please let me know.
I own an ASUS RT-AC56R router. I followed every guide from portforward.com to open game ports for my PS4. I'm checking various sites that claim to show forwarded ports, but all of them say "closed." It's confusing—I think I did it right, but I'm not sure. I have the port range, local IP, and protocol set correctly.
It might not be you or your modem; the ISP could have those ports disabled.
There might be a way to check. You can see if the modem is being blocked by looking at the error messages or logs. If you have access, opening the modem might help you identify the issue directly. It sounds like ISPs could be blocking many ports, which is definitely unusual.
If the modem includes a web interface, you may be able to access it directly. If uncertain, perform a trace route (using "tracert" in Windows Command Prompt) to any public IP address. The second IP listed in the route often reveals the modem’s location, allowing you to open it in your browser and test connectivity.
I discovered through this site's tool that all my ports are set to "stealth," indicating either your ISP or the router's firewall is preventing them. When I disable the firewall, the tool shows them as "closed." This suggests a mix of issues: my forwarding settings might be incorrect, plus the firewall is blocking them.
Most internet service providers supply a gateway device (modem and router combined). Plugging in a router into the gateway gives you double NAT and double firewalls, which can complicate port forwarding. Determine whether your setup uses a standard modem or a gateway by checking if the ISP box offers Wi-Fi access. You can connect a gateway to link your modem, effectively turning it into a standard modem. This adjustment may need to be made in the gateway’s settings or handled by your ISP. Another concern is Carrier Grade NAT, where your ISP has exhausted its available IPv4 addresses, causing shared IPs with neighbors. In such cases, your ISP would need to forward traffic for you, which they are unlikely to do. VPNs might offer a workaround but typically come with costs. To confirm your NAT type, check if your WAN IP falls within the 192.168.x.x or 10.x.x.x range, which often indicates carrier-grade NAT.
According to what I mentioned, it might be a selection menu. They integrate modems and routers into one unit. About 90% of ISPs offer these combined devices. In the US, you usually receive a single combo box, but if you need separate parts you’ll have to purchase them individually. What is the model number of the ISP’s box?
