Functionality limited to the local network
Functionality limited to the local network
Hello, I installed cameras at your friend's business and needed to enable port forwarding so he could view them. The issue is that it only functions on the local network. It seems my router's IP differs from the IPv4 shown in my public IP address, which might mean contacting the ISP is necessary. He decided to set a static public IP address. Additionally, there are no other routers on the network, and I also configured the same settings on a different TP-LINK TL-WR841N router previously, which worked perfectly. Any suggestions or assistance would be greatly appreciated.
The different IP addresses are related to CGNAT (Carrier-Grade NAT). Some internet service providers use this method since there are very few available IPv4 addresses. You might want to contact your ISP to see if it's possible to open the ports. In Brazil, some ISPs employ CGNAT, and my cousin had difficulty opening just one port—she reached out to her provider, who then allowed it. It seems only a single port was accessible.
