I am using a ZTE wi-fi router. My laptop's private IP is 192.168.1.2 where Apache server is running on port 8080. I added the NAT rule to forward http traffic to my laptop.
Protocol - all
Starting port - 8080
End port - 8080
Local IP - 193.168.1.2
However when I browse [public_ip]:8080 shows nothing. when I browse [public_ip]:80 I can log into the router.
How to be sure that ISP is blocking or router is not forwarding?
I tried disabling dhcp, still the same result. I port scanned using nmap, fallowing is the result.
