Wanted to forward a custom port for which I first assigned static local IP to the device and added port forwarding rule for that local IP address, But the port is not being forwarded. I check port forwarding with GRC | ShieldsUP! — Internet Vulnerability Profiling and it keep showing "STEALTH" instead of "OPEN!" and I AM running the application (for which the port has to be forwarded) before checking the port. Am I missing something? UPnP, DNZ, etc are those options should be enabled? (Tried enabling DNZ but It was still not working). I was able to forward a port easily with my old ZTE router but its just not working with this router. Please help.
