Q-See QT52X DVR User Manual


 
If for some a port or ports that you forwarded are not listed in the Router, and if you look on
the SCRIPTS on left side and you see a message that the port already exists (Red box in image below),
then you want to change the Port 80 to 85 in DVR and start over again.
Once you get the DONE message that the ports have been forwarded, test if the Ports are working
by clicking on number 7 in the image below.
