I am using TP Link router and local internet provider GTPL. I have server on which I am hosting my website but not able to access it using public ip. I am able to access in same lan with local ip like
**But not with below**

Please see my router configurations in following screen shot.

The public IP address is not yours; it's shared between multiple customers. In other words, you're behind CGNAT (Carrier-grade NAT) and your network is not reachable from the outside.

Several results on Google confirm that GTPL has been using CGNAT for the last several years.

(If the address were really yours, generally it would show up in the router's "Status" page – you wouldn't be seeing a second "private" address there!)
