You only have one router at home with a private WAN IP address. Your online games are using strict NAT, and it's a double NAT setup. The second router you're connecting to is blocking the required ports. Your ISP isn't helping with calls. You can still reach that second router's admin panel by its IP (like 192.168.0.1) if you need to enable bridge mode or similar features.
Do you have LTE mobile internet? If yes, there’s nothing they can do since it’s the current setup. Consider switching to another provider if possible.
It's referred to as carrier-grade NAT. The best solution would involve your ISP's assistance. They'll need to handle port forwarding on their side, which they might or might not do. Another option is checking if they can provide you with a public IP address. Otherwise, it seems there might be a way to use a VPN service or a VPS that you can connect to for bypassing Carrier Grade NAT.
Thank you for your message. I explored alternatives to ProtonVPN and found other options that might help with a stricter NAT. Regarding VPS, it’s a virtual private server service that offers more control over your network connection. Would you like details on how it works?
A VPS is a virtual private server that you lease. It connects to a VPN tunnel linking your home network with the server. This setup functions similarly to a VPN service, but the connection remains exclusive to you. Consider checking if your ISP provides a public IP address—some offer it for a fee.
Your current setup remains secure, but switching to a public IP could affect privacy and security depending on the provider's policies.
In Murica technically it's possible. However, residential setups here rarely use carrier-grade NAT unless you're on LTE. My Comcast service provides both IPv4 and IPv6 public IP addresses. Usually these dynamic IPs change regularly, while static ones stay constant. Problems usually arise when someone attempts a DDoS attack. Your provider likely switches to carrier-grade NAT because they’re running out of available IPs or trying to save addresses. We’re currently limited to IPv4, though all providers can assign IPv6. IPv6 will eventually resolve this shortage. There are plenty of IPv6 addresses available—about 18 billion for each user. Most ISPs haven’t adopted IPv6 yet; they’ve only had it for about two decades.
