That’s a key issue now. You need to determine whether your public IP comes from your ISP. Since you’re not comfortable with your router, look for internet details there. The WAN address is set by your ISP—if it begins with 10.x.x.x, 172.16.x.x or 192.168.x.x, you’re using a carrier-grade NAT. Anything else indicates a public IP. Avoid sharing your WAN address; verify it on the router, not your computer, as the router displays only the private IP assigned to your device.
It would be unusual to encounter a double native in a combo I haven’t seen before. What’s the WAN address? 184.53.32.210, IDC. Keep it as Auto.
Double NAT occurs when you link a router to a combo device. As mentioned earlier, most ISPs offer combo units. Many users then purchase a router and face issues with port forwarding or strict NAT settings. In this scenario, the person has a regular cable modem and a separate router—this setup simplifies things.
It might just be the right setup. I used an old Dlink router that required a restart even with a sneeze near a switch. It was a really bad design. Don’t try that. Also, ensure your portforwarding device has a fixed IP address or the DHCP server has reserved the IP. This applies when you lose power and your equipment restarts with new IPs from the router. Additionally, confirm that the service you’re running actually needs portforwarding to be active—ports only open when there’s real traffic requiring them. For instance, if you’re hosting a Minecraft server, the server must be up before ports can respond.
If the issue persists, switch the computer to a DMZ setting just to test functionality—don’t keep it there long-term. If it works then the problem is likely with the router; if not, the ISP may be blocking your connection and you should reach out to them for assistance.
