Connect via a double NAT setup for remote access to your Raspberry Pi.
If the "Modem" supports WiFi and multiple Ethernet ports, it functions as a gateway—either a modem or router. In this scenario, you likely have two routers. Most US ISPs provide gateway services for a monthly charge. Still, I’d guess you might be using AT&T Fiber; hope you’re okay with that. Their gateway seems terrible according to what I’ve heard, and switching it to bridge mode could be tricky.
I'm using a modem (or whatever the fiber setup is) linked to my own router. Metronet seems to operate its own fiber network, which is limited to certain states.
Check if your router's WAN IP falls within the private address range. That would mean you're using double NAT. I checked the ISP's website but found limited details—likely because they're a smaller provider compared to companies like Comcast.
I think they’re a relatively new ISP...our former governor advocated for ISP choices in KY since Spectrum isn’t doing well. I’m not entirely sure, but I believe Metronet operates its own network rather than using a leased one. I don’t have much background on networking overall, but I’m managing my own router. I checked my public IP address—it begins with 184.x.x.x. My local router’s address is 192.168.1.1... Do you mean that?
That’s a standard public announcement. It seems they’re handling things on their side, or your port configuration might be incorrect. For reference, most ISPs won’t assist with setting up your own gear. If you received the router from them, they should support you, but with your own device you’ll need to troubleshoot it yourself.
I thought so... A neighbor who knows more about networking told me they use a double NAT. It might just be a configuration they can adjust for a cost.
Like I said, Your IP address does not fall in the range for CGNAT NAT. So they are not double NATing. Most likely something is not configured on your end right. Also keep in mind that switching ISP's means new IP address. Also most ISP's provide a Dynamic address. Meaning it changes periodicly. Services like No-IP can be used to help with this issue, OR you pay for the static IP. Also I would highly suggest using a VPN to connect remotly to devices on your network. Just for the sake of security. The only thing that sucks, is each router does port forwarding a bit diffrently. They really dont have a standardized interfrace. So it can be a challenge setting stuff up. https://en.wikipedia.org/wiki/List_of_as...ess_blocks That shows the reserved IP address which are not used on the Internet and the internet routable ones. Your IP is with in the Internet routable address. That would not happen if you had two layers of NAT.
Sure, I get it now. When we had the Spectrum coax ISP, we received a dynamic IP address, and I didn’t face any issues connecting from home. I’m still using the same router, and all the port forwarding configurations remain unchanged compared to when I was on Spectrum.
As mentioned before, IP addresses can change and are often specific to an ISP. I’ve heard Comcast customers reuse the same IP for years, while others get a new one each day. The situation is quite varied. Consider NO-IP, which handles dynamic IP challenges. More importantly, you may want to configure a VPN server to ensure a secure connection to your network over the internet. A VPN establishes a protected pathway across the web between locations. Large companies use them so employees can safely access their systems. Don’t confuse this with a standard VPN service like PIA, which operates differently by routing traffic through its servers to obscure your activity and reduce ISP throttling based on traffic type.
