Aztech Router DSL7002GRV(S) firewall setup for bitcomet

To whoever able to help, a big thank you. I have been issued the subject Aztech router DSL7002GRV(S) when I upgraded to fibre broadband recently to replace the existing 2wire router. In the firewall section, I have opened up ports forwarding for bitcomet. Thereafter I ran bitcomet and my port was blocked as per yellow signal. Subsequently, I called the tech support from Aztech (very difficult to get through). I got through the tech support guy as was told no action is needed, just install bitcomet and it will go through the firewall automatically. Hence, I got no joy from the tech guy. So for those that have a solution to my problem, my kind appreciation if you can share on this thread. Thank you
