For port forwarding to work, you must make sure that:
- Router has public IP address;
- Router can reach the end device;
- End device has correct gateway set;
- Port numbers are all working

Hi,
I am using this from more then 5 month but there is this causing this problem several time port open and close so there is no any issue so for i find with
- Router do not have a public IP (I have public ip) - LAN devices which you are trying to reach, do not have a correct gateway ( i have correct gateway so far i am using this from year) - Bad external/internal port numbers. (it is same port number external and internal port connection 80 8000 554)
Best regards
